Product Introduction:

Hollow winding pipe is a kind of pipe made of high-density HDPE, which is formed by extrusion and then winding. It is an ideal wellbore for inspection wells. Holes can be opened at any position of the wellbore to install the manifold. During construction, the length of the wellbore can be determined according to the buried depth of the inspection well seat.
Features:
◆Anti-chemical corrosion: Not affected by acid, alkali, or salt, and will not rust or scale.
◆Long service life: Material aging takes about 110 years, and the design life of the pipe is 50 years.
◆Strong impact resistance: It still has good impact resistance below freezing point, which is better than UPVC, PP and other materials.
◆Light weight: The density of polyethylene is less than 1g/cm3, which makes loading, unloading, transportation and installation easy.
◆Low water resistance coefficient: n-0.008-0.009, generally designed to be 0.001, while the concrete pipe n-0.013-0.014, compared with the same diameter pipe, improves the flow rate and speed.
◆Good wear resistance: The wear resistance is much better than concrete pipes, and better than UPVC, PP and other pipes.
◆Easy to connect: It adopts two-way socket connection, which is convenient and fast.
◆Environmentally friendly products: The products are 100% recyclable and do not pollute the environment.
◆Smoothness: The smooth pipe wall is easy to backfill, the construction is fast and the quality is stable.
◆Low overall cost: small water resistance, large flow, can reduce size, use small diameter pipes, low engineering costs, and low daily maintenance costs.
