  HDPE double-wall corrugated pipeIts main material high density polyethylene (HDPE) has excellent chemical stability, aging resistance and environmental stress crack resistance. And at the time of production, HDPE double-wall corrugated pipe, which is mainly made of raw materials, is a flexible pipe. The following is a detailed introduction for your friends.

HDPE double-wall corrugated pipe is light in weight, convenient in handling and connection, fast in construction and simple in maintenance. When the construction period is very tight and the conditions are not good, its advantages will be more obvious. It is also favored by everyone because of its small coefficient of friction and large flow. Mainly HDPE as the material made of corrugated pipe, can be larger than (651~254) with the caliber of other pipes. In other words, under the same flow requirements, HDPE double-wall corrugated pipes with relatively small pipe diameters can be used. It is resistant to low temperature impact because its embrittlement temperature is -70 degrees Celsius. In general low temperature conditions (-30 degrees Celsius) construction, no need to take special protection measures, convenient construction in winter, and HDPE double-wall corrugated pipe has good impact resistance. Good chemical stability Except for a few strong oxidants, many chemical media have no destructive effect on it. The soil, electricity, acid and alkali elements of the general environment will not damage the pipeline, will not breed bacteria, will not scale, and its circulation area will not decrease with the increase of operating time. And it has a long life. Under the condition of not being exposed to the sun's ultraviolet rays, the service life of HDPE double-wall corrugated pipe can reach more than 50 years.

HDPE double wall corrugated pipe also has excellent wear resistance. It has been proved that the wear resistance of HDPE is several times higher than that of steel pipe. It can be slightly bent along the axial direction and is not affected by a certain degree of uneven settlement of the ground. It can be directly laid in a less straight groove without pipe fittings. It has the advantages of light weight, small drainage resistance, strong compression resistance, corrosion resistance, and convenient construction. It is an ideal material to replace cast iron pipe and cement concrete pipe. And its construction is more convenient, because of light weight, easy transfer and connection, convenient construction, simple protection and operation. In the case of tight construction period and poor construction conditions, other advantages are becoming more and more obvious. HDPE double-wall corrugated pipe can pass a larger flow rate than other pipes of the same diameter. That is to say, under the same flow requirements, the double-wall corrugated pipe with a smaller diameter can be selected. In addition, it also has excellent low temperature resistance and impact resistance. The embrittlement temperature of HDPE double-wall corrugated pipe is -70 ℃. Under normal circumstances, there is no need to take special protective measures during low temperature (above 30 ℃) construction, and winter construction is more convenient.

The above article introduces the relevant information about HDPE double wall corrugated pipe. If you don't know before, you can read it. Well, that's all for today's knowledge point. I hope it can bring help to relevant people.
