What is the installation specification of PPR water supply pipes, and what is the process?

The first thing you need to pay attention to when installing PPR water pipes is to prohibit smashing water pipes, especially in winter, because PPR water pipes are cold and brittle.

PPR water pipes are installed by hot melt welding, connecting pipes and fittings together. Before welding, clean the welding part of the water pipe and check whether the water pipe has cracks at the port.

The hot melt temperature of PPR water pipe is generally 260 -270, which will lead to poor welding or water leakage if it is lower or higher than this temperature. According to the PPR welding specification, the welding depth, heating time, operation time and cooling time of PPR water pipe are different according to the different pipe diameters

pipe outside diameter(mm): pipe diameter (mm);

welding depth(mm):welding depth(mm);

heating-up time（sec.): heating time (seconds);

processing time（sec.): operating time (seconds);

cooling-down time（min.): cooldown time (min);

In addition, it should be noted that after the installation of the water pipe, a pressure test is required, and the installation of the water pipe is completed after the pressure test.

No, you don't. The expansion joint will be used for the drainage and water supply of PVC, which is a quick connection.

Although renovation workers are often used for decoration, we don't need to operate directly, but we still need to understand the installation process of PPR water pipes, so let Tuba Rabbit bring you some PPR water pipe installation today. I hope it will be helpful to you in terms of relevant process knowledge.

Home improvement PPR water pipe installation process.

Once the pipes and fittings are functional, they will be inspected by the owners and workers of the industry. Water pipes should try to choose brand materials, such as Zhongcai, Pilsa, Baidie, etc., but beware of counterfeit products. If you have an anti-counterfeiting mark, you can view it through **.

Don't forget the certificate of acceptance of the product.

The installation of hot and cold water pipes should be kept hot and cold, cool, and the spacing should not be less than 30mm. Use a pencil to set the position of the upper and lower metal pipe clamps. The distance between the two points is not less than 800mm, and then the hole is drilled at the positioning point with an electric hammer.

Screws for metal pipe clamps. After the wooden wedge is driven into the hole and the metal pipe clamp is nailed to the wooden wedge, the screws must be tightened into the wooden wedge to prevent loosening.

Hot melt according to the measured dimensions. The temperature is controlled at 260 °C. If the temperature is too high, the pipe wall will be deformed due to thermal deformation. After hot melting, the water pipe and pipe head will be quickly connected for 5-7 seconds to ensure the tight binding of the splice ring.

Place the connected hoses on the rack, tighten the pipe clamps one by one with a screwdriver, paying attention to the corners and corners and the nozzles must be tightened firmly. The valve installation position or tease should be accurate and flat (calculate the thickness of the tile), easy to use and easy to maintain.

All plugs are sealed. Use a pressure test pump to measure the water pressure 8-10MPa. Half an hour later, look at the pressure gauge. The normal condition is that the water pressure drops, which is qualified. If it fails, there may be a problem with the pipe or a leak in the pipe connection.

Wrap the raw tape around the plug to prevent water leakage, then tighten the plug. Pipes embedded in walls and floors should be treated with anti-corrosion treatment and protected with cement mortar.

Finally, the owner or supervisor will accept the laying of the entire water pipe, which should be laid horizontally and vertically. Whether the spacing between the hot water pipe and the cold water pipe is up to standard and there are no leaks.

Home renovation must know the PPR water pipe installation process.

Now many friends like to choose to use PPR water pipes, I hope the above preparation for you PPR water pipe installation process information can help you. You can also log in to Tuba Rabbit to view more related content and information.

What should I pay attention to when installing PPR water pipes? Installation precautions

PPR pipe is a commonly used material for household water pipes, but many people may not know the installation method of PPR water pipes, so what should be paid attention to when installing PPR water pipes? Below we will bring the precautions for the installation of PPR water pipes, let's take a look.

PPR Water Pipe Installation Precautions:

1. The pipes should be stacked horizontally on the flat ground to prevent twists and turns, and the stacking height should not be exceeded, and the pipe fittings should be stacked layer by layer, and should not be stacked too high.

2. When transferring pipes and fittings, you should be careful to prevent oil pollution, and it is forbidden to hit violently, touch with sharp objects, throw, fall, roll and drag.

3. PPR water pipe device shall not hit the pipe and pipe fittings with hard objects, especially at lower temperatures. It is necessary to cut the pipe in a straight direction axially with the pipe, and insist that the cut is clean and flat.

4. The hot-melt connection should be made in strict accordance with the welding depth of the rules.

5. The hot melt connection should be carried out strictly in accordance with the welding time of the rules.

6. When the hot melt connection, the maximum violation point of view between the pipe and the pipe fitting shall not exceed 5 degrees.

7. When the pipe is twisted, the radius of the twist shall not be less than eight times the diameter of the pipe, and it is forbidden to heat the twist with an open flame.

8. The metal thread is designed with a tapered thread, which can be sealed with hemp or plastic bag when connecting, and cannot be overtightened. Grandiose.

9. When two pipes are interspersed and stacked, it is necessary to use winding pipes.

10. After the directly buried hidden pipe is sealed, the direction of the pipeline should be marked on the wall or on the ground, and the bridge and direction of the pipeline should be marked, and it is forbidden to impact or nail sharp objects such as metal on the pipeline.

11. When the water pipe is hot-melt connected, if the operating environment temperature is less than 5, the heating time should be extended by one-half, and it is necessary to prevent the pipe fittings and pipes from facing the direction of the vent when they are connected.

Summary:When installing PPR water pipes, the installation personnel will carry out strict pressure test tests under the supervision of the superintendent, so when the node is accepted, we only need to pay attention to the problem that the PPR water pipes and pipe fittings valves are installed firmly, the position is correct, and there is no leakage at the connection. Then observe whether the position of the pipeline is hot on the left and cold on the right, and then check whether the installation position of the faucet and valve is flat, flexible, normal operation, and smooth water outflow.

That's itWhat should I pay attention to when installing PPR water pipes? Installation precautionsAll of it.

In the process of home decoration, hydropower engineering is an indispensable decoration process, in the choice of water pipes, the most common is PPR water pipes, because waterway engineering is a hidden project, in the process of home decoration, if you are not careful, there will be problems that affect the future residence to repair will be very troublesome. Today, Home Improvement Network will introduce you how to install PPR water pipes and the PPR water pipe installation process.

1. After the water pipes and fittings enter the site, they will be accepted by the owner and the workers together. Try to choose brand materials for water pipes, but beware of counterfeit products, with anti-counterfeiting marks can be inquired, don't forget to check the product's certificate.

2. The installation of hot and cold water pipes should be hot on the left and cold on the right, and the spacing should not be less than 30mm. Use a pencil to determine the position of the upper and lower metal pipe clamps, and the spacing between the two points is not less than 800mm, and then use an electric hammer to punch holes in the positioning points.

3. Nail the screws of the metal pipe clamp. After nailing the wooden wedge in the eyelet, and then nailing the screws of the metal pipe clamp on the wooden wedge, be sure to drive the screws tightly into the wooden wedge to prevent loosening.

4. Hot melt according to the measured size. The temperature is controlled at 260, the temperature is too high and the pipe wall is easy to be scalded and deformed, and the water pipe and the pipe head are quickly connected in 5-7 seconds after hot melting, so as to ensure that the fusion ring is tightly combined.

5. Put the connected water pipes on the shelf, tighten the pipe clamps with a screwdriver one by one, pay attention to the stress point at the corner, and the nozzle must be tightened firmly. The valve installation position should be correct and flat (calculate the thickness of the tile paving), which is easy to use and repair.

6. All plugs are sealed, the water pressure is measured by the pressure test pump 8-10MPa, and the pressure gauge is seen after half an hour, and the normal situation is that the water pressure falls, which is qualified. If it is not qualified, it is likely that there is a problem with the pipe, or there is a leak in the pipe connection.

7. Wrap the raw material tape around the plug wire to prevent water leakage, and then tighten the plug. Pipes embedded in walls and floors should be treated with anti-corrosion treatment and protected with cement mortar.

8. Finally, the owner or supervisor shall accept the laying of the entire water pipe, and the laying of the water pipe should be horizontal and vertical, and firm. Whether the interval between hot and cold water pipes is up to standard, and there is no leakage.
