FAQ
Plastic coated water pipe is especially suitable for the following environments:
Compared with the traditional metal water pipe, plastic coated water pipe has the following significant advantages:
Superior anti-corrosion performance: the plastic-coated layer can effectively isolate the metal from contact with water and air, prevent corrosion and rust, and extend the service life.
Water quality guarantee: the plastic coated layer is made of food-grade materials, non-toxic and harmless, will not pollute the water quality, to protect the safety of water.
Light weight: Compared with metal water pipe, plastic coated water pipe is lighter in weight, which is easy to carry and install, and reduces the construction difficulty and cost.
Strong impact resistance: plastic coated water pipe has good toughness and impact resistance when impacted by external forces, not easy to rupture.
The quality inspection of plastic coated water pipe includes appearance quality inspection, coating thickness measurement, EDM leakage detection, adhesion test, bending test, flattening test, impact test and so on. These tests can ensure that the plastic coated water pipe meets the relevant standards and requirements in the manufacturing and use process.
Plastic coated water pipes can be selected in colors according to customers' requirements, and common colors include red, white, blue and gray. Its wide range of specifications, from Φ15 to Φ300 (or even larger, such as DN15-DN2200), can meet the needs of different application scenarios.
The design life of plastic coated water pipe can reach 50 years, which is mainly due to its excellent corrosion resistance and stable physical properties.
When installing the plastic coated water pipe, bending, thermal processing and welding cutting and other operations should be avoided. If cutting is required, the cutting surface should be painted with non-toxic room temperature curing adhesive equipped by the manufacturer. In addition, plastic coated water pipe should not be buried in the reinforced concrete structure layer, and welding is prohibited during installation.
There are various connection methods for plastic coated water pipe, including screw connection (applicable to DN15-DN100), groove connection (applicable to DN65-DN400), bimetallic welded connection (applicable to DN100-DN800), flange connection (applicable to any caliber) and welded connection (applicable to any caliber).
Plastic coated water pipe is widely used in fire sprinkler system and life water supply and drainage, coal mine field of gas extraction, slurry transportation, ventilation system, chemical anti-corrosion pipeline (can be buried in the ground to transport corrosive media containing acids and alkalis, etc.), the protection of communication cables (in the urban and rural cable renovation), the central air conditioning HVAC circulating water system and so on.
Plastic coated water pipe combines the advantages of steel pipe such as high strength, easy to connect, water impact resistance, etc., and at the same time overcomes the shortcomings of steel pipe in contact with water, easy to corrode, pollution, scaling, as well as the plastic pipe is not high strength, poor fire performance and so on. It also has good corrosion resistance, sealing properties, thermal expansion properties, as well as light weight and excellent plasticity, easy to constru
Plastic-coated water pipe is coated with a layer of plastic in the inner wall or outer wall of the steel pipe (or even inside and outside), such as polyethylene (PE), ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC), and other organic substances and the composition of the steel-plastic composite pipe.
