Cleaning of IPS (PPH) pipes and fittings

Cleaning of IPS (PPH) pipes and fittings

1. Check cleaning objects of IPS (PPH) pipes and fittings

Before cleaning IPS (PPH) pipes and pipe fittings, first of all, the distribution of pipes should be made clear, and the service life, service condition, blockage, buried and exposed parts of buildings should be understood for damage. Before dredging, pay attention to understand the material. In addition to cast iron and ceramics, there are other materials in the system, such as equipment and pipes with structural materials such as cement.

2. Subsection cleaning

In order to facilitate the cleaning of IPS (PPH) pipes and pipe fittings, it is generally divided into several small cleaning sections. The method of segmentation is mainly based on the volume of pipes, the height of floors, the convenience of cleaning, and the possibility of segmentation. Generally, three or four floors in a unit is a better section.

3. Acceptance

After the cleaning of IPS (PPH) pipes and pipe fittings, the acceptance shall be carried out to check whether the pipes are dredged, cleaned and unblocked to meet the customer’s requirements.

Introduction PVC tee

Introduction PVC tee

PVC tee is also called pvc fitting tee or tee pvc pipe fitting. pvc Tee joint is used at the branch pipe of main pipe. It has three openings, that is, one import and two exports, or two imports and one export.

PVC tee is a kind of PVC chemical pipe fitting, which is used to change the direction of fluid. There are T-shaped and Y-shaped pipes, equal diameter pipe orifices and reducing orifices. It can be used for water transmission pipeline, oil transmission pipeline and various liquid chemical material transmission pipelines. It is mainly used in medicine, water conservancy (water-saving irrigation, water supply and drainage), energy (oil, natural gas, nuclear industry), construction and other engineering fields.

Tee can be divided into metal material and non-metal material according to material. The metal tees are carbon steel, stainless steel, alloy steel, etc., and the screw tees; the non-metal tees are PVC, UPVC, CPVC,IPS,PPR,PP etc. According to the connection mode, it can be divided into two types: snap type and threaded connection. According to the shape, it can be divided into T type and herringbone type.

        

Tee is classified according to pipe diameter:

1. Tee with the same diameter: tee with the same diameter of main pipe and branch pipe

2. Reducing tee: tee with branch pipe diameter smaller than main pipe diameter

The tee is classified according to the docking form:

1. Butt welded tee: refers to the tee pipe fittings welded after butt joint with the connecting pipe fittings.

2. Socket tee: it is a tee pipe that is welded or welded after the connecting pipe is inserted into each end of the tee.

3. Ferrule tee: it is a tee fitting with ferrule connector at each end, which is inserted and then tightened.

4. Threaded tee: a tee fitting that is threaded to a fitting.

Tee is classified by material and branch type:

It can be divided into stainless steel tee, carbon steel tee, copper tee, PVC tee, etc.

1. Straight tee: it is the tee fitting of vertical main pipe of branch pipe.

2. Inclined tee: it is a tee fitting with a certain angle between the branch pipe and the main pipe.

Precautions when purchasing tee

The renovation of waterways is the most important part, which should not be neglected at all. To do a good job in waterway reconstruction, the selection of waterway decoration materials is very important. Many owners may think it’s better to buy a good water pipe. In fact, in addition to the water pipe, various water pipe fittings are also needed during the water transformation. Although these fittings are not impressive, they are indispensable.

(1) First, determine whether the controlled medium is oil or water.

(2) Calculate the flow of controlled medium m3 / h.

(3) According to the controlled medium and its design flow, choose the diameter of three-way temperature regulating valve.

(4) According to the valve body material (cast copper or t cast iron), connection type (f flange, G pipe thread, ZG taper pipe thread), valve structure type (Z rotary valve type, H slide valve type), temperature regulating range and installation type, determine the model of three-way regulating valve.

(5) According to the different flow directions of the three valve ports, the three-way temperature regulating valve can be used in the confluence or shunt control occasions.

(6) The function of the combined three-way temperature regulating valve is to mix two different temperature fluids through the valve into the third temperature fluid whose temperature is between the first two. The valve has two inlets (B is the high temperature inlet, C is the low temperature inlet) and one outlet (a). The temperature sensing element is installed at the outlet (a). The function of the shunt type three-way temperature regulating valve is to divide a kind of fluid into two ways in proportion after passing through the valve. When the valve closes one outlet, it opens another outlet. This valve has one inlet (a) and two outlets (B is the bypass return port, C is the shunt cooling port).

(7) The three-way temperature regulating valve can replace a two-way valve and a three-way connecting pipe.

(8) There are six installation types of rotary valve type three-way temperature regulating valve, which are suitable for any pipe connection. The installation type is selected according to the actual pipe connection of the system.

(9) The three-way temperature regulating valve can be installed at any position, but the emergency manual device surface shall be installed at the position convenient for operation.

(10) In order to prevent the impurities in the medium from jamming or blocking, a filter should be set in front of the three-way temperature regulating valve.

5 points for attention in PVCU pipe production process

5 points for attention in PVCU pipe production process

PVC-U pipe is one of the most widely used pipes. It is also relatively frequently used in building decoration. Therefore, the requirements on the quality of pipe are very strict, and there are many precautions in the production process.

There are five specific points:

In the production process, because PVC is a heat sensitive material, even adding heat stabilizer can only increase the decomposition temperature and extend the stability time without decomposition, which requires that the molding and processing temperature of PVC should be strictly controlled. Especially RPVC, because its processing temperature and decomposition temperature are very close, often due to improper temperature control caused decomposition phenomenon. Therefore, the extrusion temperature should be determined according to the formula, extruder characteristics, head structure, screw speed, position of temperature measuring point, error of temperature measuring instrument and depth of temperature measuring point.

1. Temperature control

Temperature control is an important control factor in extrusion operation. The temperature of the control factors needed for extrusion is barrel temperature, diameter temperature and die temperature. The temperature is too low, the plasticization is not good, the appearance of the pipe is not glossy, the mechanical property is poor, and the product quality cannot meet the requirements: the temperature is too high, the material will decompose, the product will change color and so on.

2. Screw speed

With the increase of screw rotation speed, the extrusion volume will increase, so the output can be increased, but it is easy to produce the phenomenon of poor plasticization, resulting in the roughness of the inner wall of the pipe and the decrease of the strength. At this time, the head pressure should be adjusted to achieve the best output and quality. The temperature control of screw affects the conveying rate, plasticization and melting quality of materials. The extrusion pipe needs cooling water to reduce the screw temperature, which is conducive to improving the plasticizing quality. The screw cooling water temperature is about 50 ~ 70.

3. Traction speed

In the re extrusion operation, it is very important to adjust the traction speed. After extrusion, melting and plasticizing, the material is drawn after continuous extrusion from the head, thus entering the setting device, cooling device, traction device, etc. the traction speed should match the extrusion speed. Generally, in normal production, the pulling speed should be about 1% ~ 10% faster than the extrusion speed of pipe.

4. Compressed air and pressure

Compressed air can blow the pipe and keep the pipe roundness. It is required that the pressure should be appropriate. The pressure is too small, the pipe is not round, the pressure is too large, the core mold is cooled, the inner wall of the pipe cracks, is not smooth, and the quality of the pipe decreases. At the same time, the pressure is required to be stable. For example, the pressure varies from big to small, and the pipe is prone to produce the status quo of slub.

5. Temperature of sizing device and cooling device

Different sizing methods and cooling methods are used to extrude different plastic products. The cooling medium can be air, water or other liquids, and the temperature needs to be controlled, which is mainly related to production efficiency, product internal stress, etc.

The above five points are the points that general manufacturers need to pay attention to when producing PVC pipes. As long as the above five points are well done, we believe that the PVC pipes made will surely ensure better quality.

What to do if PVC pipe is frozen?

What to do if PVC pipe is frozen?

For the PVC water pipes, faucets or water meters that have been frozen, do not bake them with fire or knock them with hard objects. Only use hot towel, warm water and other methods to defrost them. Do not pour boiling water, or bake them with open fire or knock them with metal instruments.

After the PVC water pipe is frozen, the valves in front of the meter and in the room shall be closed, and the faucet shall be slightly unscrewed, so as to eliminate the pressure in the pipe caused by the expansion of the frozen volume of water and avoid the cracking of the PVC water supply pipe or PVC pipe fittings.

Method 1: Sprinkle PVC water pipe with hot water

First, wrap the frozen place with cotton and linen fabric, then sprinkle it with hot water to thaw it slowly. In the process of watering, it is best to use the method of interval watering, so as to make full use of the heat of hot water to melt the frozen PVC pipe.

Method 2: blow PVC pipe with electric blower

If the PVC water pipe you use is slightly frozen, you can use a hair blowing hair dryer. When you blow it, you should not blow it to a place, but blow it up and down, so as to defrost the water pipe.

Method 3: cover PVC pipe with hot towel

If your PVC water pipe is frozen in a small area, you can try to heat the towel with hot water and cover the water pipe. Use the heat of the towel to make the ice in the water pipe melt.

Method 4: increase indoor temperature

If only part of the PVC water pipe is frozen in the room, a furnace can be placed in the room to raise the indoor temperature; or a blowtorch can be used to heat the wall with water pipe to raise the temperature of the wall.

Adhesion method of PVC pipe fittings

Adhesion method of PVC pipe fittings

When installing PVC pipes, they are often used together with PVC pipe fittings. However, some users may have water leakage or pipe fittings damaged in the installation process. The first reaction is that it is caused by material problems, but the most frequent problem is due to problems when PVC pipe fittings are glued.

1. Bonding method of PVC pipe fittings

A. Before bonding, PVC pipes and PVC pipe fittings should be used for trial insertion once. Under normal circumstances, when the trial insertion reaches 1 / 2-1 / 3 of the specified depth, the fitting clearance is ideal. The proper fitting clearance of PVC pipes and PVC pipe fittings is the premise to ensure the bonding effect.

B. The connection between PVC riser and horizontal branch pipe shall be installed with inclined tee or four-way pipe. Two PVC fitting 45 ° elbows or one PVC fitting 45 ° elbow and one PVC fitting 45 ° tee shall be used for connection between the outlet horizontal pipe and the riser

These two methods can not only reduce the chance of pipe blockage, but also reduce the formation of water tongue at the joint.

2. Key points for adhesion of PVC pipe fittings

The size of PVC pipe fittings and pipes shall conform to the corresponding standards and specifications; if the fit gap is too small, it is quite difficult to insert them to the specified depth due to too much resistance after the application of adhesive, especially for the pipe fittings with large caliber. The operator may have the following possibilities:

A. When the PVC pipe fittings are inserted in half, they can no longer be pushed in place. At this time, they can neither enter nor exit

B. Although it is not inserted in place, it can make good use of it. As a result, it is out of joint and leaking during the shallow pressure test.

C. A sledgehammer is used to pad the board and smash it forcibly. Although this method can be inserted to the specified depth, the method is improper. Especially in high temperature weather, the adhesive will solidify quickly after brushing. When the bonding surface is being solidified, it is still forced to insert with the help of external force, resulting in the decrease of bonding strength, leaving a hidden danger to the normal operation of the pipeline;

I’ve read the relevant knowledge about the bonding method of PVC pipe fittings and the precautions for PVC pipe fittings. I hope to help the major users when the PVC pipe and pipe fittings are bonded.

Problems in PPH(IPS) pipeline installation

Problems in PPH(IPS) pipeline installation

As there is no national code for design and construction acceptance of IPS(PPH) pipes and fittings, problems are easy to occur in use. According to the experience in construction supervision, the following problems should be paid attention to in construction supervision of IPS(PPH) pipes and fittings:

1. Selection of IPS(PPH) pipes and fittings: IPS(PPH) pipes and fittings (homopolymer polypropylene pipes), whose raw materials are β modified, have uniform and fine beta crystal structure, have high chemical stability and high temperature resistance, and are widely used in steel plants (acid pickling, acid regeneration, acid mist), flue gas desulfurization, process cooling water and corrosion-resistant medium transportation in chemical industry.

2. Supervision of the construction process: as IPS(PPH) pipes and fittings are still in the promotion stage, the construction personnel do not grasp the construction process in place, and the new type of pipe requires high technical level of the construction personnel, making the construction difficult. Therefore, the pre job training for construction personnel is particularly important. The supervisor shall pay special attention to the pipeline connection in the field inspection. The place where IPS(PPH) pipeline is most likely to leak and burst is the pipeline connection. The main connection methods of IPS(PPH) pipe and fittings are hot-melt connection and flange connection. The precautions are as follows: the special fusion tools provided by the manufacturer shall be used. Before connection, the pipe interface position and pipe fittings shall be cleaned to ensure that they are clean, dry and oil-free, and the pipes and pipe fittings shall be marked. The fusion temperature shall be checked regularly to ensure that they are at the correct value. During fusion, the pipe fittings and pipes shall be prevented from sliding outwards and shall not rotate after heating, Strictly observe the holding time and cooling time. IPS(PPH) pipeline pressure test shall be conducted in strict accordance with the specification requirements, only in this way can the normal and reliable operation of the system be ensured.
