Polyvinyl chloride PVC pipes

What is a Polyvinyl chloride (PVC) pipes?

Polyvinyl chloride (PVC) pipes are widely used for different applications in several industries. PVC pipes are highly durable and can resist a lot of pressures and temperatures. However, the PVC pipes also require special techniques to ensure that they do not break down. In addition to breaking down, the PVC pipes are also more vulnerable to external damages.

PVC pipes are mostly used in water pipes system. The PVC pipe is also widely used in sewer pipeline in both large and small scale systems. PVC pipes can resist a large pressure of water and are very resistant against any external damages.

Does PVC pipe bend easily?

Polyvinyl chloride PVCPVC pipes are highly flexible and can stretch significantly. They can easily accommodate bends with no problems. It can resist any pressure applied on it and can extend its life span considerably. However, PVC pipes are prone to breaking down if they are exposed to various stress factors such as heat, cold, static electricity, alkalis, acids etc.

Apart from its resistance to pressures and temperature, PVC pipes are also resistant to corrosion. However, the PVC material tends to corrode when exposed to salt spray and chlorides. A chloride spill can easily dissolve the PVC lining and cause a leak. This may eventually result in freezing and loss of cool water. Apart from PVC-M, PVC pipes are also vulnerable to external damages due to corrosion and heat.

Are PVC pipes expensive?

These PVC pipes are comparatively more expensive than other PVC pipes. The PVC material used in PVC pipes contains numerous impurities. Therefore, it is necessary to treat the PVC pipes with a special water treatment agent, otherwise it may block the air circulation within the piping system. If the PVC pipelines are laid outdoors, it is necessary to lay the PVC pipes horizontally.

One of the main PVC pipe fittings that are prone to corrosion is the T-bar, which holds the PVC pipe together. If the T-bar is not maintained, the PVC pipe may split. Split ends may also occur due to improper PVC pipe handling. PVC pipes may become rusty if they are not maintained properly. It is important to keep the PVC pipe joints clean and they should be made using a stainless steel cutter. When they are made using steel cutting tools, the PVC pipe joints will remain unaffected from rusting.

What would cause a PVC pipe to crack?

A PVC pipe can experience stress cracking at various pressure levels. Stress cracking is known as hydrostatic pressure. In case of PVC pipes that are installed outdoors, a PVC-M joint can encounter hydrostatic pressure, which may crack or break the PVC pipe. The high pressure may lead to failure of the PVC pipes leading to major water problems.

For proper and long-term usage, PVC pipes should be properly maintained. Proper PVC pipe care ensures that the PVC pipes do not break down easily due to exposure to weather. Improper PVC pipe maintenance can also lead to health problems for the people living nearby. A PVC pipe can also be damaged by heavy metals such as copper, iron, lead or mercury. In case of any damage to PVC pipes, you should contact a good plumbing contractor who will solve the problem in the timely manner.

Should PVC pipes be replaced?

In case of any damage to PVC pipes, you should remove the old PVC pipe and expose the new pipe. The old PVC pipe is then marked with a black line. This mark tells you how much PVC pipe is exposed. If you find more than three quarters of the PVC pipe exposed then you should use a high pressure air machine to blast away the old PVC pipe. It is very important to remove the old PVC pipe because otherwise you will have to incur additional expenses of repair.

After the blasting process, you should clean the surface of the pipe. For this purpose, you require a pipe cleaning brush or a rag. You should dip the brush in the sealant and scrub the surface of the pipe thoroughly. Make sure you choose a nozzle that matches the diameter of the PVC pipe and the flow rate.

How do you clean a PVC pipe?

Thereafter, you should clean the inside of the PVC pipe. For this task, you need a vacuum cleaner hose. With the help of the vacuum cleaner hose, you should clean the interior of the polyvinyl chloride pipe. Cleaning of PVC pipes is very essential before starting the sealing process.

Once the surface of the PVC pipe is clean and free of debris, you should add the sealant. Add the sealant in even coats one after the other. Let the sealant dry completely for at least 24 hours. If you feel that the sealant has dried up and is no longer effective, you can reapply it. This process will ensure that you do not face any PVC leakage issues in the future.
