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.
Product features
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.
Applicable fields
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.
