HDPE hollow wall winding pipe production equipment

1, HDPE hollow wall winding pipe to adapt to the wide temperature range. At minus 80 degrees to zero on 60 DEG C environmental conditions, the pipe can not freeze damaged or leaking expansion. Superior wear resistance. Than the steel pipe, cement pipe wear using long life, up to 50 years.

2, stable chemical properties. Acid and alkali, salt ability strong, resistant to sewage, wastewater and chemical corrosion, soil rot material corrosion resistance, no rust. Light weight. Weight cement pipe 1 / 8, convenient transportation, convenient construction without large construction equipment.

3, HDPE hollow wall winding pipe water. Drain liquidity is superior, smooth inner wall, wall roughness rate n value of about 0.001. Therefore, the transmission fluid when compared to the frictional resistance is small, relative to the same diameter cement pipe in the same operating conditions, the water quantity can be increased 4 mediated attack. Therefore available with smaller diameter winding pipe to replace large diameter cement pipe.

4, HDPE hollow wall winding pipe impact. "H-shaped" structure is adopted in the pipe wall. Impact resistance, pressure, large elastic deformation and not easy to damage, for any foundation has good adaptability. Aging, pipe, usually black, can withstand storage and in the construction process of the sun Zhishai. Pipe can be first in the ditch outside the connection, used excavators to ditch. In urban drainage engineering construction, reduce the construction time and the cost of the project.
