The excellent characteristics of PE water supply pipes […]

The excellent characteristics of PE water supply pipes are widely used in all walks of life. They not only have the rigidity of high-density polyethylene, but also have good flexibility, non-moisture absorption, non-toxic and odorless, excellent electrical insulation and excellent acid resistance at room temperature. Alkali, salt, organic solvent, good cold resistance, and remarkable advantages in creep resistance.

The application of PE water supply pipe has long life and corrosion resistance, and the buried pipe has been reliably used for more than 50 years in the temperature range of -60℃-60℃. The pipe wall is smooth, which can develop the medium water flow and expand the total flow. Compared with the same metal pipe, the PE water supply pipe can transport a higher total flow and save the driving force consumption. Low cost, less project investment, compared with metal pipelines, can reduce project budgets. It is light in quality, with a density of only 1/8 of that of steel pipes. It is easy to migrate, easy to bumps, simple welding method, less earthwork backfill, no anti-corrosion treatment, and convenient construction speed. PE water supply pipes have better resistance to ground stress than steel pipes, and can greatly reduce pipeline leakage and pipe burst probability in engineering project applications, plus the safety factor of gas transportation. Polyethylene pipe has excellent flexibility. When the foundation subsides or earthquake occurs, it is likely to deform and not crack.

How to refit PE pipe

During the renewal and transformation of the PE pipe circuit, there must be no connectors in the pipe. Only then can it be used and used in the subsequent process to not easily cause damage due to safety accidents such as power failure. Below we have a grasp of common PE pipe modifications. What are the problems?

Circuit routing should master the "short-term spacing between the two ends", and no endless winding is not allowed. This will not only lead to dead lines, but also continue to expand the capital investment for power reform. The turning of PE pipes with a diameter of less than 25 uses a pipe bender. It is not allowed to turn with an elbow. Right-angled bends usually lead to dead lines. Of course, the most important thing is to use the method of embedding to carry out the renewal and transformation, because that is the safest. If there is a connector, it is necessary to leave the cassette buckle panel at the joint, which will be convenient for disassembly and maintenance in the future. There is no need to run too many threads in a PE pipe. You should pull it after threading to see if it can be easily pulled. The operation must be carried out strictly in accordance with the operating requirements to prevent unnecessary inconvenience.
