The double-walled corrugated hdpe drainage pipes
Standard applied: GB/T19472.1-2004
The double-walled corrugated hdpe drainage pipes are formed via extrusion using the raw material of the HDPE, which has the hollow corrugated rings perpendicular to the axis and smooth inner wall.
Its quality is assured, and meets and even surpasses the relative requirements.
Combined toughness and flexibility: The double-walled corrugated hdpe drainage pipes has sufficient mechanical performance and toughness, combined with excellent flexibility; and it also has strong compressive strength and good anti-impact performance as well as strong adaptivity to the bad environment on-ground and underground.
Strong adaptivity: The corrugated shape on exterior wall can enforce the load capacity of the pipe in earth, easy for the continuity of installation on uneven floor.
Strong low-temperature resistance: The double-walled corrugated hdpe drainage pipes would not crack and leak under freezing level in the environment of the temperature at -60�C .
Excellent anti-abrasion performance: The double-walled corrugated hdpe drainage pipes has low friction coefficient and small resistance so that it can convey medium, water drainage and sewage fast.
Environment protection: PE is non-toxic and has no chemical effects and no heavy metal additives. It uses recyclable materials, low-carbon, environment-friendly and healthy.
Strong chemical-erosion resistance and anti-aging performance: HDPE molecules have no polarity and therefore the stability of the fittings is excellent with strong resistance to chemical erosion. The product can bear the effect of acid and alkali in earth and be applicable in special circumstances. The double-walled corrugated hdpe drainage pipes could have a lifespan of over 50 years when used under normal conditions, thus significantly lowering the expenses generated in maintenance and replacement.
Of light materials: The double-walled corrugated hdpe drainage pipes are easy to load, unload and transport. The installation of the product is easy and reliable. No large-scale engineering equipments are needed in the construction of urban drainage projects. Meanwhile the installation period is shortened to effectively lower the expenses generated in installation and maintenance.
The product is applicable for PE double-walled corrugated pipes for underground drainage and communication casing in which the medium temperature is no more than 45C , as well as for industry drainage and sewage pipes, which.
Municipal domain: underground rain and sewage drainage for municipal projects and residential communities;
Agriculture domain: Irrigation water supply and flood drainage; Industry domain: sewage transportation in sewage treatment factories and garbage processing plants, vent ducts in chemical industry, and he fluid transportation for chemical industry and mining.
Other domain: protection casing pipe for telecommunication cable.
