Question:

Spiral drain pipe fittings are not special pipe fittings

Spiral drain pipe fittings are not special pipe fittings

Answer:

NoThe drainage tube is made of high density polyethylene (HDPE) and other additives the exterior is a new drainage plastic pipe corrugated, corrugated pipe is through holes in the permeable groove tube around the outside of the outsourcing geotextile acupuncture and processing. According to the types of bellows, they can be divided into single wall permeable bellows and double wall permeable bellows.

Because the product of the tube holes in the trough, and elongated, effectively overcomes the planar circular hole is easy to block defects affect product drainage effect, according to the requirements of different drainage tube hole size is 10mm * 1MM-30MM * 3mm, and at 360 degrees, 270 degrees, 180 degrees, 90 degrees. Within the scope of the uniform distribution, widely used in highway, railway subgrade, subway engineering, waste landfill, tunnel, greening slope protection drainage belt, athletic field and high water content caused by agriculture, gardening, and underground irrigation and drainage system. It has become the three main products of civil engineering construction (water seepage, drainage) with soft permeable pipe and plastic blind ditch. According to the drainage pressure of municipal drainage network, double arm bellows and straight wall pipe can be used. The pressure of the straight wall pipe is stronger, and it can be used in the special pipe of large-scale drainage and sewage pipe network.

1 vertical compression to the outer diameter of 40%, immediate unloading, the specimen does not rupture, not stratified.2, the temperature at 0 degrees, high 1M conditions, with a weight of 1Kg heavy hammer, impact 10 times, should be more than nine times without cracking.3. The inner wall is even and smooth. The water permeable holes are evenly distributed below 1/2 in the height of the trough. The number of holes at the height of the trough is not more than 10% of the total number of 1/2.4, water area is larger than 45cm2/M
