- Specifications
Introduction
Standard:ISO 4427-2,EN 12201-2,AS/NZS 4130,BS 6920,GB/T 13663.
The end: Plain end
Length:6meter,or customization.≤63mm coiled pipe.
Color：black inside and out side,other color customization accepted.
Characteristics
1.Has a density of 0.95-0.97,lighter than PVC,and does not require heavy machinery for installation and transportation.
2.Good cold resistance,seismic resistance,impact resistance,and toughness.
3.Good acid and alkali resistance,no scaling,and good chemical resistance,and can be used for chemical and seawater transfer.
4.Good elongation and bending flexibility,and small size pipes can be curled to reduce fittings and leakage.
5.Meets food grade requirements and can be used for milk and edible oil transfer.
Applications
1.Pressure pipes:
·Drinking water pipes
·Seawater pipes for aquaculture
