The operation points of PVC water supply pipe production

 The operation points of PVC water supply pipe production

Our xing yin plastic manufacturing plant has a good reputation all over the world in terms of the quality of the PVC water supply pipes produced by our xing yin plastic manufacturing plant. Because we treat it with a rigorous attitude and careful operation during production, let me introduce you to pay attention to the production and operation of water pipes. 

Operating instructions for the production of PVC water supply pipes

 In order to ensure that the quality of the PVC water supply pipe fittings produced has no problems and can also improve the production efficiency, it is required that the extruder must be used correctly.

Because of the characteristics of the conical screw of the extruder, the feeding section has a larger diameter, and the heat transfer area and sheer speed of the material are relatively large, which is conducive to the plasticization of pipes and pipes. The small diameter of the screw in the metering section reduces the heat transfer area and The sheer speed of the melt enables the melt to be extruded at a lower temperature.

When the screw rotates in the barrel, it plasticizes the mixture of PVC-U water supply pipe fittings and faces the machine head, so as to achieve compaction, melting, mixing, and homogenization; and the purpose of exhausting and dewatering is completed. Feeding equipment and screw drive equipment adopt frequency conversion speed regulation, which can complete synchronous speed regulation;

The extrusion die head part is the key part of the molding of PVC water supply pipe fittings. It takes the compacted, melted and kneaded and homogenized PVC and the follow-up materials are passed through the screw to face the die, and the product is shaped and quality controlled.

How to construct PVC pipes in summer

 How to construct PVC pipes in summer

PVC pipe is a kind of pipe that is very commonly used in construction now. Due to the weather, the current climate is warming, especially during summer construction. There are more high temperatures and rainy weather. If the construction is improperly operated, it is easy to cause deformation of the pipe. The pipe will be broken during the pressure test. The following editor summarizes a few precautions for pipeline construction in summer.

Precautions for summer construction of PVC pipes

1. During the construction of PVC live casing in summer, because the PVC pipe has the characteristics of thermal expansion and contraction, there must be a certain amount of space reserved during the connection of the live casing. Please refer to the following table for details

pvc pipe	Leave a gap
Below 63mm	10mm
75mm-110mm	15mm
140mm-160mm	20mm
Above 200mm	25mm

2. There are mostly small animals in summer, especially when installing irrigation pipes in farmland. When the PVC pipe is installed, pay special attention to the cover of the pipe mouth to prevent small animals from entering the pipeline and affecting the pressure of the pipe and normal water flow in the future.

pvc pipe construction

3. If construction is not carried out for a short period of time, in order to prevent long-term sunlight exposure to the pipe body and aging of the PVC pipe body, the height of the pipe should not exceed 1.5 meters, and the sockets should be staggered, and the pipe body should be covered with shading nets.

PVC pipe storage

4. During the pressure test of the PVC pipe, the pressure must be maintained for 1 hour before the pressure can be relieved. If the pressure changes between 0.05 MPa during the maintenance time, it is proved that the pipeline has no water leakage or rupture. If the pressure changes greatly, the pipeline can be proved In the event of water leakage or rupture, the pressure test should be stopped in time and the pressure test should be carried out again after the repair is completed.

PVC pipe pressure test

5. Due to a lot of rain in summer, when the pressure test of the PVC water pipe is completed, it should be backfilled in time to prevent the collapse of the pipe ditch from affecting the normal construction and damaging the pipe body, causing unnecessary trouble. Since rainwater is more frequent, it must be compacted during the backfilling process to prevent the occurrence of cavities in the pipe trench, causing uneven force on the pipe body during the pressure-bearing process, which affects the pressure resistance of the pipe.

How to distinguish TYPES OF PLASTIC PIPES, DIFFERENCES, AND THEIR USES

 How to distinguish TYPES OF PLASTIC PIPES, DIFFERENCES, AND THEIR USES

TYPES OF PLASTIC PIPES, DIFFERENCES, AND THEIR USES

Not sure what type of pipe to install? In this article we analyze the different types of plastic pipes, we explain their differences and uses to know in what type of installations to use them.

PVC drainage pipe

ADVANTAGES OF PLASTIC PIPES

The introduction of plastic in the construction sector was a revolution never seen before. It made it possible to change elements that weighed a lot for simpler and lighter versions, which allowed them to be used by a single operator instead of needing the force of several, also lowering the cost. For example, by its nature, plastic has very good properties when it comes to transporting fluids. In addition, there are as many varieties as projects you can have in hand. Each version adapts to the type of fluid and structure you need to work with.

And it is precise because of this last advantage that you should know the different types of plastic pipes, as well as their unique differences and characteristics.

PVC PIPES

PVC is the type of plastic most used in the manufacture of plastic pipes. PVC is also known as polyvinyl chloride due to its components. It is mainly used in plastic pipes for drains and water supply and similar aqueous fluids, its physical and mechanical characteristics make it the ideal material for this purpose. There are PVC pipes both colored and in gray tones. We can also find varieties of oriented PVC improving its resistance

And although it is common to find it in standardized measurements, PVC pipes have the advantage that they are easily cut with a conventional saw, which allows us to adapt the length to the place where we want to pass the tube. It is not necessary to have specific cutting tools as in the case of other materials of much higher hardness.

As a detail, to join the PVC pipes together we will use couplings of the same material, it is only necessary to use a specific adhesive for PVC that acts as a chemical weld for a perfect and durable finish.

We are a professional PVC pipes manufacturer. We can make PVC pipes according to customers’ requirements. We can produce expanded PVC pipes, special-shaped PVC pipes and so on

 

POLYETHYLENE PIPES

Polyethylene (PE) is the second most used type of plastic in pipes. Its main difference compared to PVC is that polyethylene is more flexible. For this reason, we tend to use it for underfloor heating, household waste disposers, or irrigation systems.

The lightness and low weight of polyethylene speed installation and lower cost. The process of installing polyethylene pipes is simpler and lighter than that of other materials. In fact, polyethylene pipes are cut using a pipe cutter, a sturdy cutter, or professional scissors. As an interesting detail, to proceed with the union we use toothed male accessories and small pliers that press the joint to seal.

ABS PLASTIC PIPES

No, when we talk about ABS we are not talking about the braking system of cars. Well, at least not in this case. In fact, in this case, when we talk about types of plastic pipes, the abbreviations ABS refer to acrylonitrile butadiene styrene, a type of plastic that is harder than PVC and polyethylene, and which is usually marketed in black and is the more common, for example, in sewage systems.

When buying ABS plastic pipes we will find the same standardized measurements as in PVC pipes.

To proceed with the union we must use couplings of the same type of ABS plastic and seal with cement to ensure complete hermetic closure.
A very important point of ABS plastic pipes is that it will be the local regulations that decide whether we can install ABS or PVC plastic pipes. Under no circumstances is it allowed to combine both in the same installation.

CPVC PIPING

CPVC is a more rigid version of PVC plastic. This extra stiffness is achieved with a small variation in its composition and is used mainly in potable water piping systems. Its resistance allows the passage of both hot and cold water and carries an additional level of safety for a product as sensitive as the water our families drink.

To make the joint we will need special couplings of the same CPVC material, to fix the joint we use primer and conventional PVC cement. We can easily cut it using a tube cutter.

Its main characteristic and the reason why the CPVC type of plastic is perfect for the passage of hot water and heating elements is that it perfectly resists temperatures of up to 80º continuously, and even occasionally boiling water when we have to unclog.

CPVC pipes and fittings are very flame retardant, they are very suitable for fire protection system.

CPVC FIRE SPRINKLER FITTING

CPVC FIRE SPRINKLER FITTING has excellent bacteriostasis, heat resistance, corrosion resistance, blocking resistance, high pressure resistance, chlorine resistance and other superior performance. It is very suitable for fire protection piping system all over the world. At the same time, it has high rigidity and flame retardancy.

MULTILAYER PLASTIC PIPING (MC)

The plastic known as multilayer combines thermoplastic and aluminum at different concentric levels. The most widely used thermoplastics in this type of pipe are PERT (high thermal resistance polyethylene) and PEX (cross-linked polyethylene). Both are extruded with a natural resin to create a first layer that determines the diameter. Subsequently, the first layer is joined with an aluminum tube to which a second outer thermoplastic film is added.

Due to its versatility, this type of pipe is used mainly in the installation of hot and cold water, and for the medical supply of oxygen.

POLYBUTYLENE PIPES

Their characteristic is that no special tools are needed for joining them or any type of adhesive, their installation is very simple thanks to their flexibility and low wall thickness. In addition, due to its ease of cutting, it is possible to carry out the installation without having precise measurements.

On the other hand, this type of pipe presents a low heat diffusion, which implies that the pipe will remain colder for hot water installations and will better resist low temperatures, together with its flexibility make it a pipe with good resistance to freezing.

POLYPROPYLENE TUBES(ppr pipe and fitting)

Polypropylene pipes(ppr pipe and fitting).Polypropylene can be used for drinking water and heating systems. To install it we need professional tools since the complete union requires a heat fusion seal. By not having mechanical joints, we reduce the risk of leaks that do occur with other joint materials, due to the contraction and expansion of their components.

PLASTIC PEX PIPING

Cross-linked polyethylene or PEX plastic tubing is commonly used in gas and water supplies. This type of plastic pipe is one of the most flexible models, in addition to providing high resistance to lime and chlorine, so it does not corrode.
We can find PEX pipe in a wide variety of different sizes and cut easily with a pipe cutter.
When making the union between two or more PEX plastic pipes, we will use brass or plastic accessories.

In short, broadly speaking, these are the main types of plastic pipes and their differences, each model has different characteristics that indicate the type of installation and fluids where we should use it. Make sure of the use you want to give to the pipe since depending on the material you will have an ideal pipe for one or other uses and spaces.

pvc pipe joint type

 pvc pipe joint type

There are many types of PVC pipe joints. They connect every part of the piping system together so that the piping helps to transport water from the water supply system to the sink. Without pipe connectors, the entire city’s pipe system would be unusable.

What is a PVC connector?

pvc pipe joint

Pvc joint is to connect PVC piping system together to change the direction of water flow.
It is mainly divided into two aspects,Plumbing connectors PVC joint, and Furniture grade connectors PVC joint.

Plumbing connectors
Plumbing connectors are often used in pipeline drainage systems, house water supply systems, and sewer systems. They connect every corner of the city and are used in people’s houses, office buildings, and urban plumbing systems.
Plumbing connectors are not beautiful, but very practical.
If you are a wholesaler of PVC pipes or a wholesaler of PVC pipe fittings, you can buy them in our factory.
If you are an individual, you can buy them from our worldwide PVC pipe wholesalers or PVC pipe fitting wholesalers.
Furniture grade connectors
Furniture grade connectors show you the other functions of PVC pipe fittings. They are not limited to the basic idea of ​​connectors. They are often used in supermarkets, shopping malls, and some special customized products.
Furniture-grade connectors can be connected with PVC pipes to make shopping racks, display racks, or other commodities. Similarly, if you are a wholesaler of PVC pipes or a wholesaler of PVC pipe fittings, you can buy them in our factory.
If you are an individual, you can buy them from our worldwide PVC pipe wholesalers or PVC pipe fitting wholesalers.

Whether it is Plumbing connectors or Furniture grade connectors, you can DIY PVC products.

Most Common Types of PVC Pipe Connectors

Just like there are several types of PVC pipes, there are many types of PVC pipe connectors.

• Adapters
• Bushings
• Caps and plugs
• Couplings
• Elbows
• Flanges
• Nipples
• Tees
• Crosses
• Saddle Tees
• Unions
• 3 way elbow
• 4 way elbow
• 5 way elbow

Adapters

The adapter is generally a threaded joint, and the adapter for garden hoses is unique，garden hose adapters provide an easy way to connect your home garden hose to a PVC pipe line. We carry a full selection of durable fittings for connecting to male and female hose ends to suit your unique needs.

Adapters come in most standard materials, including brass, copper, malleable, ABS, PVC, and steel.

Bushing

Bushings help you join pipes that have different sizes.

Bushing is divided into socket type and thread type.People make bushings from all sorts of piping materials, such as ABS, brass, copper, malleable, stainless steel, and PVC.

What is PVC bushing,This article can let you know more about it.

Caps and plugs

pvc fitting end cap for water supply has a socket opening for connecting to a pvc pipe or fitting, and is suitable for closing or terminating the end of a pipe or fitting.

Plugs have the same purpose, but you put them inside the fitting. They are threaded, so you can continue using the same pipe.

Plug is used to plug off a fitting in PVC systems. Plug is only designed to work with threaded fittings.Plug is made with a threaded end so that they will work with any fitting in the PVC system.  plugs are pressure tested to meet all industry standard and can handle heat up to 140 degrees Fahrenheit.

Other than PVC, caps, and plugs are available in brass, copper, ABS, malleable, and steel.

Coupling

A coupling extends the pipe’s run.Coupling is divided into normal connection and Compression connection. Coupling can connect two PVC pipes of different sizes.

Couplings usually have female threads, but sometimes they can be unthreaded. You can take unthreaded pipes and either glue them or solder them with copper.

Apart from PVC, they come in ABS, copper, brass, malleable, and steel.

Elbow

The elbow is a joint that connects two PVC pipes and changes the direction of liquid flow. They are usually 45-degree elbows and 90-degree elbows. Of course, there is also a reducing elbow, which is used to connect two different size PVC pipes. Elbows with sockets also have threaded elbows. Divided into internal thread elbow, external thread elbow.

what is pvc elbow? This article can let you know more about it.

Elbows are one of the most crucial connectors in most plumbing projects. They come in PVC, but also in brass, copper, ABS, steel, and malleable.

Flanges

Flanges connect pipes. This is a great idea in case fixing PVC leaks is necessary. Pipes that you use with flanges end up either welded or threaded to the flanges.

Then, you seal them together with bolts. Professionals typically use flanges in industrial applications, especially when there is high pressure involved.

People use them for residential pump systems, as well, usually in the bathroom. These are the connectors that mount the toilet to the floor and extend to the drain.

Flanges come in PVC, copper, brass, and malleable. PVC flanges are the ones that you can find in toilets.

Nipples

Nipples look like short pipes that remind of stubs. They have male threads on both ends. Nipples connect two different straight pipe runs. Short nipples have a unique look, as they have threads from one end all the way to the other one. In other words, the threading goes throughout the length of the pipe. This helps them ensure very tight connections.

Nipples come in brass, copper, steel, malleable, and, of course, PVC.

Tees

Tees resemble the shape of a Latin letter “T.” They help you connect three or more pipes to ensure good water flow.

Essentially, it looks like a fairly long coupling that has an outlet on one side. This outlet comes at a 90-degree angle from the body of the connector. Its size depends on the size of the pipe.

The side outlet is usually referred to as the ‘top,’ and the straight-through part of the fitting is the ‘run.’ If the tee’s run is smaller than the top, this is called a ‘bull head’ connector.

Tees come in PVC, ABS, CPVC, brass, steel, and copper.

Crosses

Crosses are essentially tees with two tops. With them, you can connect four PVC pipes.

They are more limited compared to tees, and they come in less materials. Because of this, many professionals opt to use several tees instead of a cross connector.

Other than PVC, crosses come in malleable and brass.

Saddle tees

If you need to add a pipe or tee to an existing pipe quickly, saddle tees are the way to go. You can also find them under the name ‘snap-tee.’ They are a great way to add a new pipeline without cutting an existing PVC pipe. Commonly, people use saddle tees on irrigation systems. This way, you will easily add another sprinkler line. To complete this task, you need to take a saddle tee and glue it to the pipe. After everything is set, you have to drill another hole, and everything is good to go.

Saddle tees come in PVC only.

Unions

Unions are more or less the same as couplings. If couplings are inconvenient or impractical, professionals use unions. Unsoldered couplings require you to thread pipes into them.

Unions, opposite to that, have their own nut that creates a seal that connects two pipes. For example, this is a great choice if you have two fixed pipes that you can’t thread into couplings.

This way, any future repairs will be much easier and straightforward. There are even dielectric unions that professionals use to join pipes made from different metal materials.

This is enabled thanks to their anti-corrosion properties. However, unions come with a few downsides. The main one is that you can’t use them with LP or natural gas.

Unions come in PVC, brass, CPVC, malleable, brass, and steel.

3 way elbow、4 way elbow、5 way elbow

This is a special connection tool. We have two products: furniture level and pipe level.
Our customers buy these three products for display racks, clothes racks, and the like.
They can connect PVC pipes in three directions or multiple directions

Are there different standards for PVC pipe joints?

There are many standards for PVC pipe joints produced by our factory, Schedule 40 PVC fitting, Schedule 80 PVC fitting，BSP, ASTM, GB, and so on.
It can meet the needs of different countries and regions.

Are there different sizes of PVC pipe joints?

Just like there are many standards for PVC pipe joints, there are also many sizes. This can be done so that you can better connect to PVC tubes of different sizes.
Different standard PVC pipe joints have different size standards.

A good side of PVC connectors is that you can use them with pipes made from non-PVC materials. Suppose this is the case; the nominal size is not as important anymore.

Now you don’t need to look at the outside diameter of everything. Instead, the pipe’s outer diameter needs to be compatible with the inner diameter or the connector.

However, a 2″ pipe of copper, for example, might not fit a 2″ PVC pipe connector.

A nominal size only matters if both the pipe and the connector are PVC.

This is why it’s important to know all existing types of PVC pipe connectors. Different connectors are made in different ways.

Understanding them and understanding how manufacturers make them is crucial to finding a pipe that fits.

We are a professional manufacturer of PVC joints. We can wholesale PVC pipes, wholesale PVC pipe fittings, wholesale PVC joints.
