How to deal with the burst of PVC pipe fittings

 

How to deal with the burst of PVC pipe fittings

PVC pipes can be seen everywhere in life, mainly because they are relatively light and easy to install and repair. Even if the household pipe is broken, you can repair it yourself. So what should I do if the PVC pipe fittings burst?

Treatment method after bursting of PVC pipe fittings:

1. The number of leaks after the water pipe bursts is generally directly related to the water pressure in the pipe. Regardless of whether the water is dripping or gushing out, what you should do at this time is to immediately close the valve of the water supply pipe and report to the local property department for repair.

2. Bundle the damaged part of the water pipe with the special tape for repairing the water pipe.

3. In addition, it is also possible to repair cracks in water pipes with glass fiber tape or ring air resin adhesive.

4. If the water pipe burst is serious, you can wrap the broken part of the water pipe with a towel, which can prevent the water from radiating everywhere, and can also introduce the water into the placed bucket, so that the PVC pipe manufacturer will avoid huge waste. At the same time, the valve of the main water pipe in the household can be closed, and the tap water supply in the house can be completely intercepted.

5. If the cause of the pipe burst is that the pipe is too old, you should find a plumber to stop the inspection and repair it in time.

Causes of PVC pipe burst

1. The purchased PVC pipes are inferior quality pipes and contain recycled materials. This kind of pipe is prone to bursting after being used for a period of time.

2. The PVC pipe cannot meet the design pressure requirement. When the water supply pressure is too high, the pipe burst, the drum breaks, and the bag pick up.

3. The PVC pipe is too long and the expansion joint is not used, resulting in excessive thermal expansion, pipe bursting, drum braking, and bag lifting.

When purchasing PVC pipes, you must purchase qualified products according to the purpose of use, and install them in strict accordance with the procedures during installation, so that there will be no pipe bursts, drums, and packages.

In plumbing engineering, these ppr fittings are indispensable

 In plumbing engineering, these ppr accessories are indispensable.

When using PPR pipes in plumbing engineering, what accessories are needed?

1. ppr elbow

In plumbing engineering, PPR pipes need to be used when the direction of the pipe needs to be changed. The size of the ppr elbow should be matched with the PPR pipe. If it does not match, the welding will definitely not be firm. As soon as water flows, it leaks. However, for PPR pipelines in pipeline engineering, the fewer joints the better. The more joints, the greater the risk of water leakage.

2. ppr tee

In plumbing engineering, PPR pipes also use three links. The function of the ppr tee is to divert the water flow. For example, one water flow needs to be divided into two directions, and three PPR pipes are connected by ppr tee fittings. When welding, the technical requirements of the water master are high, and the three outlets of the tee must be tightly welded.

3. ppr coupling

In pipeline engineering, when the length of PPR pipe is not enough, PPR can be used for direct connection. However, the direct quantity should not be too much, otherwise, it will be troublesome to repair and even need to be replaced with new pipes. However, it is also not possible to blindly save pipes and directly weld a lot of PPR coupling, which not only troubles construction, wastes time, but also increases the hidden danger of water leakage.

4. ppr pipe clamp

ppr fitting clamp

PPR pipes in plumbing engineering should be fixed by pipe clamps. The distance to fix thePPR pipe clamp is related to many factors, such as the diameter of the pipe, the water pressure, and so on. However, the more pipe clamps are not the better. Too many pipe clamps waste materials, and it is unnecessary. Too few pipe clamps make the pipes easy to fall off the slope, and they are easy to be damaged in windy weather.

5. ppr ball valve

 

In landscaping PPR pipelines, various ppr ball valves and ppr stop valves are also needed. For example, the main valve, check valve, etc. of a section of pipeline. In each place, the corresponding valve must be used to control the pipeline in the entire pipeline project.

What are the interface methods of PVC water supply pipe and fittings

 

What are the interface methods of PVC water supply pipe and fittings?

pvc pipe and fitting connection

The interface methods of PVC pipes and fittings are based on different environments, and the interface methods are different. Today we will learn about the interface methods of PVC water supply pipes and fittings.

  1. There are usually three methods for the connection of PVC water supply pipes: rubber ring connection, glue connection, and flange connection.

   (1) The rubber ring interface method is to expand one end of the PVC pipe into a socket with a groove through an active flaring machine, put a flexible rubber sealing ring, and insert the unflared end of the other PVC pipe into the sealed enclosure Convergence is completed in the socket.

   (2) The flange connection method is to connect the PVC pipe with traditional PVC pipes, butterfly valves, gate valves, flow meters, etc., and the connected end of the pipe is connected with the PVC-U flange and then fastened with screws.

   (3) The glue sticking method is to expand one end of the PVC pipe into a smooth socket and apply special glue on the surface of the other end of the unflared pipe and the inner and outer surfaces of the expanded socket, and then insert them into each other. Finish convergence.

   2. There are usually two ways to connect PVC water supply pipe fitting: glue interfaceand flexible interface method.

   (1) The flexible interface method is the pvc pipe fitting method to mold a socket with a groove, and an additional compression screw cap is equipped, and a compression rubber sealing ring is placed. When the corresponding pipe is inserted, the screw cap is tightened to complete the connection.

   (2) The glue connection method is to inject the socket of the pipe fitting into a smooth socket and apply special glue to the pipe at the same time to complete the connection.

Advantages of PPR PIPE

 

Advantages of PPR PIPE

PPR pipe is a new type of energy-saving pipeline product, which mainly has the following characteristics:

(1) Lightweight: density is 0.91g/cm3, ppr tube is only one-ninth of steel pipe, and one-tenth of copper pipe. Due to its lightweight, it can greatly reduce the transportation cost and the construction intensity of installation.

(2) Hygienic and non-toxic green building materials: PPR pipes are polyolefin thermoplastics, whose molecules are only composed of carbon and hydrogen, without harmful and toxic elements, and have reliable hygienic performance. The whole process of raw material synthesis, molding processing, product use, and disposal will not cause adverse effects on the human body and the environment and is called green building materials. PPR pipes can be used not only in cold and hot water systems but also indirect drinking water systems.

(3) Heat-resistance and heat preservation are energy-saving products: PPR pipe Vicat heat-resistant temperature is 131.3℃. Under certain working pressure and 70℃ working temperature, it can be used for a long time (more than 50 years), and the maximum working temperature is 95℃. Fully meet the requirements of the hot water system specified in the building water supply and drainage design code.

(4) Good heat preservation performance: The thermal conductivity of the PPR pipe is 0.23w/m℃, which is only one-twentieth of that of steel pipe (43-52w/m℃). It has better heat preservation performance. Compared with metal pipes, Used in hot water and heating systems, it can save a lot of insulation materials and energy.

(5) Hot-melt connection, safe and reliable: PPR pipe has good heat-welding performance. The hot-melt connection between pipes and fittings made of the same PPR material is the fusion of molecules and molecules, and there is no obvious interface. The entire pipeline system The connection becomes a whole, so the hot-melt connection of this method is more reliable than other pipes’ solvent bonding, mechanical connection, an elastic sealing socket connection, and the operation is simple, the speed is fast, and it is especially suitable for direct buried and hidden applications. During construction, there is no need to consider whether there will be leakage at the connection part during long-term use.

(6) Good corrosion resistance: Except for a few oxidants, it can withstand the erosion of a variety of chemical media, will not rust, will not corrode, will not breed bacteria, and will not have electrochemical corrosion.

(7) Water flow resistance is small: the inner wall of the ppr pipe is smooth, will not scale, and the wear resistance system is only 0.007, which is much lower than that of the metal pipe, and the water flow capacity is 30% higher than that of the metal pipe of the same specification
(8) The ppr tube has no pollution to the environment during production, construction, and use, and will not cause white pollution problems, and is a green product.

best pipe for water supply

 

water supply pipe

Drinking water pipes are totally basic facilities for any sanitation system in homes, premises, or offices. Choosing the right type of material for your drinking water connections is a key factor for its proper functioning. Therefore, in this post, we will teach you the types of drinking water pipes and which is the best option.

Plastic Water Pipes

They are used in all types of installations, there is even some heat-resistant plastic pipe that can be used in heating installations (hot water), although it is not highly recommended, better copper.

PVC pipes and CPVC pipes are probably the most widely used pipes today.

CPVC is a more rigid version of PVC.

Polyethylene (PE) would follow in the ranking of most used pipes.

hdpe water supply pipe

The main difference compared to PVC is that PE is more flexible.
Plastic pipes called PER (cross-linked polyethylene) are also widely used since it is an extremely robust and durable plastic.

They are stronger than normal PVC pipes and contain more chlorine, making them safer and less likely to affect water quality.

We are going to list some of its advantages:

They are resistant to corrosion.
The plastic tubes are flexible and easy to fit.
They are cheaper than other materials.
The systems for joining the plastic pipes make the installation of water easy and time-consuming.
Cleaning plastic water pipes is also straightforward because most of the time it is just unscrewing. Plastic is also suitable for all kinds of water hardness.
In addition, the plastic water pipes remain rust-free.
The smooth surface of the tubes prevents the accumulation of lime and dirt. They are also resistant to acids (water alkalinity) and lime.

Copper Water Pipes

Copper water pipes are particularly strong, robust, and durable, but they are more expensive than plastic ones.
It is used in gas, heating, and plumbing installations.

Copper pipe welding requires some manual experience, so installation is more expensive and should only be done by professionals (plumbers)
The components that connect pipe sections to each other today are often press fittings (straights, deviations, or branches)

In the past, pipes used to be bent at a high cost, but today, thanks to pressure fittings, they offer a cost-effective alternative in money and time.

However, copper water pipes are not recommended if the pH value of the drinking water is too low (less than 7), that is, acidic water as it carries health risks.

Therefore, regular inspection of these types of water pipes is particularly important.

Galvanized Steel Pipes

The great disadvantage of steel is its low resistance to corrosion since in contact with air and humidity it rusts easily and can be completely destroyed.

Thus, steel pipes need surface protection, which is usually galvanized.

Galvanizing is coating one metal with another.

This is the best type of pipe for your hot water supply.

They also tend to last longer than all other types of pipes.

Galvanized steel is a traditional pipe material.

Modern versions of galvanized pipes are considered a relatively safe medium for drinking water.

However, there are potential health problems if the water supply is corrosive due to low pH.

It is mainly used for outdoor pipes, as these pipes are usually larger in diameter.

PPR pipe

Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes, and other pipes, PPR pipes have the advantages of energy saving, material saving, environmental protection, lightweight, high strength, corrosion resistance, smooth inner walls, simple construction and maintenance, and long service life. It is widely used in construction, municipal, industrial, and agricultural fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid transportation, agricultural irrigation, etc.

Drinking-Water Pipes

Drinking water pipes and fittings must be made of materials resistant to materials, gases, and metals normally dissolved in water and therefore resistant to corrosion.

The material used in each case depends mainly on the hardness of the water.

Very hard water produces limestone, very soft water causes corrosion.

The basic rule is that the materials must not impermissibly impair the quality of drinking water in terms of its food quality.

copper and PVC pipes are the most used for drinking water.

PVC pipe used only for cold water, and CPVC pipe used for cold and hot water have been around for years, and both are approved for use with potable water.

But the truth, neither of them can be described as environmentally friendly from a production or recycling point of view.

Copper pipes are the best option for water pipes.

They are durable and do not leach chemicals into drinking water.

However, copper pipes are generally more expensive and the intensive process of extraction and manufacture of copper presents some environmental imbalances.

Also, if the water has a pH value of less than 7, you will need to install a system to balance the acidity of the water, so that it does not corrode the copper.

 

what is PPR FITTING DOUBLE FEMALE THREADED BRASS ELBOW

 

what is PPR FITTING DOUBLE FEMALE THREADED BRASS ELBOW

What is the name of the pipe that connects the two elbows (tee) of the PPR pipe together? We usually call it PPR FITTING DOUBLE FEMALE THREADED BRASS ELBOW.

It is used to replace the original two ppr female elbows or ppr female tee, so why do you want this?

The place where PPR FITTING DOUBLE FEMALE THREADED BRASS ELBOW replaces ordinary elbows is usually shower mixing valve, wash basin hot and cold faucet, water heater inlet and outlet, vegetable washing tank mixing valve, and so on. Generally, the center hole distance between the shower faucet and the mixing valve is relatively fixed in an interval (13.5cm-16.5cm).

center hole distance

Because the connection between the shower faucet and the mixing valve requires the center hole distance of the ppr female pipe fittings of the two water outlet PPR pipes to be about 15cm, and not to be crooked, the two pipes are on the same level. Due to the high technical requirements, some installation masters who are not skilled in welding PPR pipes can easily install poorly. PPR FITTING DOUBLE FEMALE THREADED BRASS ELBOW and tee can solve this problem well, not only can be installed in a place like a master, And can greatly speed up the installation speed, so it is deeply loved by the water masters.

PE pipe storage and maintenance

 

PE pipe storage and maintenance

PE pipe is a widely used building material, but PE pipe has a service life, how to maintain it?

1. PE pipes should be stacked according to different specifications. The pipes below DN25 can be bundled. The coiled pipes should have the same length and the weight should not exceed 50Kg; the pipe fittings should be packed according to different varieties and specifications; products from production to The storage period between uses should not exceed one year, and the principle of “first in, first out” must be adhered to when distributing materials. When using a forklift, soft grass or foam can be placed on the forklift to avoid loss during handling.

2. PE pipes should be stacked horizontally on a flat mat. The width of the mat should not be less than 75mm, the spacing should not be greater than 1m~1.5m, the overhang of the two ends of the pipe should not exceed 0.5m, and the stacking height should not exceed 1.5m. The pipe fittings are stacked layer by layer, and should not be stacked too high.

As for the maintenance of PE pipes, it is probably the following aspects:

1. Pay attention to anti-blocking. It is common for the drainage and sewage pipes to be blocked, and one of the reasons for the blockage is that a certain section of the water pipe is stuck with a foreign body. Blocked water pipes not only trouble our lives but also cause excessive local pressure on the water pipes, which affects the life of the water pipes. To avoid clogging, we can add a floor drain at the outlet of the drainage pipe to prevent excessive foreign matter from entering the water pipe.

2. Prevent the PE pipe from being exposed to the sun or too cold for a long time. Try not to lay exposed water pipes or wrap the exposed areas with insulation materials. The water in the water pipes should be drained at night in the cold winter. If it is a gas PE pipe, it must be covered underground, because the underground temperature is relatively stable, and it will not cause unnecessary loss of PE pipe fittings due to weather.
