Large diameter hdpe pipe

HTB1bWRfKpXXXXaMXVXXq6xXFXXXM

Large diameter hdpe pipe

Product description

HDPE has very good electrical properties, especially the high dielectric strength, so it is very suitable for wire and cable. Medium to high molecular weight class has excellent impact resistance, even at -40F low temperature.

Characteristics

1. Chemical stability, thanks to the non-anode/cathode characteristic of the HDPE molecule, it has very excellent chemical stability. Except few extreme oxidizers, it is free from harm of most chemical medium, it is a environment friendly producing no bacteria and dirt, so that its flux area will never reduce with time.
2 .Easy connection operation (nainly connected through hot nelting ):fewer fittings and zero leaks
3 .Easy installation : Moving and connecting is easy for HDPE thanks to its lightweight. That means a fast and easy installation and simple maintenance. The advan-tage is especially outstanding when the time is limited and the working condition is bad.
4 .Small resistance and big flux. Bigger flux is espected for HDPE pipes than other pipes with the sane diamete. That means that a smaller HDPE can work fie the same requirements.
5 .Good flexibility (22.50). HDPE pipes are a little vertically flexible, free from badinfluence of uneven ground precipitation in some situation. It can be installed in ditch kind things without help of fittings.
6 .Excellent resistance to low temperature: its impact resistant embrittling temperature is -70, which means a protection free operation in common low temperature: 30. this is especially good fir winter installation . HDPE pipes also have outstanding impact resistance, beyond harm from water hammers 2.5 times of the metric pressure.
7 .Excellent abrasion resistance. German experiments improve that HDPE abrasion resistance is times an higher ad steel pipes.
8 .Durable use. It can be used fir more than 50 years with direct exposure to sunlight V-R.
