Is there any problem with the PPR water pipe?

If the PPR water pipe is crooked when docking, it may lead to water leakage, and it will also cause the space on the inner wall of the water pipe to become smaller or even blocked.

The joint is crooked during the installation of the PPR pipe, you can check it according to the following steps:

1. Whether there will be water leakage can be straight first, generally speaking, it is not in line with the specification, it is best to cut off and reinstall, especially the buried pipeline, which can easily cause potential safety hazards.

2. If it is not too obvious, or the construction is difficult and inconvenient for secondary installation, you can use the pressurizer to pressurize the test for 24 hours, and it can be put into use if it meets the requirements.

The laying of PPR pipelines is divided into two forms: direct burial and non-direct burial. The direct burial form includes embedded wall laying and floor surface layer laying. The non-direct buried form includes pipe wells, ceilings, laying behind decorative panels, and laying of overhead layers on the floor.

Notes:1After the water pipes and fittings enter the site, they will be inspected 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 dimensions. 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 one by one with a screwdriver, 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 maintain.

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, 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 PPR water pipe laying 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.

It depends on what part of the area, and the impact is different. As long as the operation sequence and time of heating are well grasped, the deviation is not too large, and there is no appearance problem if it is concealed. If the inner tooth elbow is welded crooked, hehe, it can only be reworked.

There is no problem with the fusion in place, as long as it is not too crooked, the interior will not have any effect, and the appearance may not be beautiful but it will not affect the use.

As long as it doesn't leak, it's fine, and remember to correct it as much as possible in the future, so that it will not only not leak but also be beautiful.

If it is crooked, it will only damage the aesthetics, but it will not affect the use.

Nowadays, as people's quality of life has improved a lot, there are more requirements for home decoration materials. The TPR pipe is the decoration material that most decorators will choose, but most people have little understanding of it. So, can PPR water pipes be bent?

What are the advantages and disadvantages of PPR water pipes? Let's explore the answer together!

1. Can PPR water pipes be bent?

PPR water pipes cannot be bent. It should be noted that when installing PPR water pipes, it must be tested by Kaimeng.

Because as long as the PPR water pipe passes the pressure test, there will be absolutely no water leakage. In addition, when installing PPR pipes, if you find that the corners or intervals are too long, you should use joints to connect them, but do not bend the pipes.

2. What are the advantages and disadvantages of PPR water pipes?

1. Advantages. PPR water pipe is a very environmentally friendly material, so it can be used directly as a tool for drinking water transportation. In addition, the joints of the PPR water pipe are connected by hot melt, so there is no leakage 100%.

At the same time, the other materials of the PPR pipe are connected by wires, although the impermeability function is weaker, but it does not contain any toxicity. In addition, the ** of PPR water pipes is also relatively affordable, and the service life is also amazing, generally up to 50 years.

2. Disadvantages. There is a good side and a bad side to any item, and PPR plumbing is no exception. It is understood that the pressure resistance and high temperature resistance of PPR water pipes are inferior.

If it is used regularly, then the temperature of the construction should not exceed 70 degrees Celsius. In addition, the length of the PPR tube is also limited, and it cannot be bent when used. In the process of construction, it is often necessary to use joints, although the pipe is low, but the joints are more expensive.

The PPR water pipe can be bent, but it needs to be bent by using a special pipe bender or heat gun to soften the sail of the excited beam and hot cover sail, and then bend it with lead hail. Care should be taken not to bend excessively when bending, so as not to affect the flow rate and service life of the pipeline.

It is made of hot melt material, as long as it is carefully bonded. It doesn't matter if it's a little slanted. It's just that it's more troublesome when installing sanitary ware. If you haven't tiled yet, it is recommended to buy a joint for two dollars to cut and correct.

It doesn't matter if it's crooked, as long as it's dissolved, it won't leak.

It won't leak, as long as the gaps inside are well fused when connected. It is possible to change the tube again.

PP-R (Polypropylene Random) pipe, also known as type III polypropylene pipe and random copolymer polypropylene pipe or PPR pipe, has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, long service life, etc., and is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheath, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. PP-R pipes are made of random copolymer polypropylene by extrusion into pipes, and injection molded into pipe fittings.

Nowadays, there are many fakes of PPR water pipes, and it is recommended to buy PPR water pipes of big brands when buying, such as Weixing, Rifeng, Jinde Pipe, etc. 1. Before inspecting the water heater, check whether the water pressure is low due to water leakage, which causes the water heater to not work properly. In the case of a water leak, turn on the other faucet to see the pressure of the water (compared to normal).

If there is no change, it means that the water leak is not affecting the normal water pressure. 2. When the water pressure is normal, the failure of the water heater should be checked. Drains are treated after the fault has been rectified.

3. The best way is to disassemble the leak and re-weld the water pipe. The second method is to bond with marble glue. Use marble glue to close the main switch in the room, drain the water at the leaking pipe, wipe off the water on the surface, and then apply it with glue.

This glue is a catalyst that only adds 1 30 when it is used, and it should be used for no less than 8 hours. After induration, it is as hard as a stone.

Answer pro 1, the safest solution is to replace the fitting pipe at the leaking location. Close the main valve, discharge the water, use PPR scissors to cut off the leaking pipe, use the PPR hot soup machine, and add a section directly. The process is not complicated, and it can be solved in 30 minutes by skilled workers.

2. Wipe the leaky part and buy it with plugging king (waterproof cement). Add a little less water, and if it is very thick, you can paste it under the large surface at the leakage position. Cast iron sewer pipes are also often remedied in this way.

3. Use polyurethane waterproof powder (generally used in the bathroom waterproof) to transfer water and brush it on the leakage.

4. Use weatherproof glue to hit the water leakage.

PPR Pipe Fitting Leakage Solution:

First of all, it is wrapped with hemp silk and then installed, and the same is true for winding it with raw meal tape. If it is a glue or welding joint, it is more difficult to solve the water leakage, and it is more difficult to solve it by yourself.

1. If it is a PVC water pipe, you can buy a PVC water pipe to connect it yourself, first cut the broken pipe, and put the interface into one end of the pipe first, so that the cutting position of the other end is just flush with the other opening of the interface, so that it.

Just enough to straighten it, then send it directly to this end so that both ends have a certain crossover distance (length) and then remove it and apply PVC glue to the inside of the two ends and the outside of the two sewer pipes.

2. Then buy waterproof tape to repair the sewer pipe, wrap it up, or use sandpaper to gently polish the newly exposed port, not too much. You can also use mortar waterproofing agent and cement to plaster it.

3. Wipe the port clean with a clean cloth. If you can't handle it yourself. It's better to find a professional company. Apply to the port with special glue and let it dry for a while; At this time, glue is applied to the inside of the "bamboo" joint.

4. Connect the port with the "bamboo" and rotate it repeatedly until it is firm. The same way to connect the other end.

5. If there is a problem with the connector, replace the connector part. If there is a water leakage in the pipe body, grind off the embroidery of the original pipe body, and pay attention to the need to inlay an iron plate that is tightly attached to the water pipe at the repair position for reinforcement treatment.

Cut off the leaking section, replace it with a new section of pipe, heat it directly and reconnect it. Leaking PPR joints are not easy to repair, so it is better to replace them directly.

The reason for the water leakage at the interface of the PPR heating pipe is that the heating pipe is not tightened at the structure, and the user only needs to tighten the interface gently.

PPR hot water pipes are generally used as heating connection pipes, and can also be used for hot water pipes of water heaters, and are often used as home improvement pipes because of their high temperature resistance and high pressure; PPR is a random copolymer of propylene and ethylene, and PP-R pipes are extruded from PP-R resin. Quality control issues of PPR pipe raw materials.

Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, long service life, etc., and are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

Answer 2: If the water leakage is serious, then it is best to replace the hot melt tube directly. Close the water valve, use pliers or wrench to remove the hot melt pipe, replace it with a new one, and then use the hot melt method to melt the joint into one to prevent water leakage.

It needs to be cut and reconnected.

Because this connector is a disposable connector, if there is a water leakage, it can only be reconnected.

The joints of PPR pipes need to be hot-melted joints, that is, they are formed at one time, and directly bonded together after being heated and melted by a hot melter.

If this is the case, the joint is leaking, it proves that the hot melt connection was not operated properly, and the joint must be cut and the hot melter must be used again for hot melt connection.

Now the joints are leaking a lot. I had to change it. It's not long enough to make a straight through.

If it is to be buried in the wall, it is better to cut it out and do it again

There is a PPR combination glue that can.

It can be welded with a welding torch that welds plastic.

If you can know where the water is leaking, try scalding the area with an electric soldering iron and letting it melt to plug the leak.

Only cut it off and replaced it again. There is no other remedy.

Check what the reason is, if it is not the right size, you can change the joint, if it is a broken water pipe, you need to change the water pipe.

At present, PPR water pipes are more common in the application of home decoration, if there is a water leak, you can try to use the following methods to solve the solution:

Step 1: Use a saw to see off the location of the PPR pipe leakage, and pay attention to the fact that the mouth must be flat.

Step 2: Then use sandpaper to polish the fracture of the pipe, but not too severe.

Step 3: Use a clean cloth to clean the port of the pipe to clean the impurities and other contaminants on it.

Step 4: Select the appropriate PPR pipe fittings and intercept the appropriate length of PPR pipe.

Step 5: first melt the pipe fittings and the intercepted PPR pipe together, and then heat melt this part together with the intercepted and fixed PPR pipe; Do not rotate when melting, just insert the link slowly.
