Many people often confuse t about the plastic covered pipes and also 3PE anti-corrosive pipelines because they are extremely similar to their look. Layered plastic pipe, additionally known as below ground layered steel pipe or steel-plastic composite steel pipeline, is the steel pipe which is thawed an organic layer with a density of 0.5 ~ 1.0 mm on the inner as well as external wall such as modified polyethylene (PE), ethylene-acrylic copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC). This underground coated steel pipe combines the benefits of steel as well as plastics. It not only has the advantages of high stamina, simple connection, water impact resistance and so on yet likewise cancels the disadvantages such as simple deterioration, air pollution, scaling, low toughness of the plastic pipe and poor fire-fighting efficiency of steel pipe in water. It offers a long life expectancy as well as even more financially with design life can reach 50 years.
Firefighting layered steel pipe is one of the most frequently utilized plastic coated steel pipe, with a steel pipe as the base pipeline, the outer wall covering high adhesion, effect resistance, deterioration resistance weather resistance kind of thermosetting powder layer and the inner wall coating food quality sanitary thermoplastic powder coating, and afterwards made by sandblasting and chemical treatment, preheating, inner paint, outside paint, curing and other post-treatment.
The functions of below ground layered steel pipe
The pipeline wall is smooth as well as burr-free, suitable for the below ground or another humid atmosphere, can stand up to very high or low temperatures.
It have a strong ability to hold up against stress, even can endure the pressure of 6Mpa.
With excellent anti-interference capacity, it can properly screen the signal interference from the exterior.
The layer itself also has great electric insulation and also does not cause deterioration.
The Spec of underground covered steel pipeline
Color: black, gray, blue, red, white, green;
Coating density: PE( customized polyethylene) finish thickness is 400um-- 1000um, EP( epoxy resin) is 100um-- 400um;
1. The plastic-coated pipe can be made use of in all sort of circulating water supply (civil distributing water and wldsteel.com industrial distributing water), fire supply of water system, building supply of water and drainage transport, city sewage pipeline;.
2. Gas discharge, mud conveying, drainage as well as air flow system in the coal mine;.
3. The chemical anticorrosive pipeline transportations various chemical liquids, such as acid, alkali as well as other corrosive media.
4. Utilized for the defense of hidden pipelines and interaction cords of electric cords as well as wires.
5. It can ensure the normal procedure of the water flow system of central air in the HVAC flow system of central air conditioning.
