How to Determine the Quality of Coating Pipe?
Manufacturers of plastic-coated steel pipes are abundant. How do we select the right plastic-coated steel pipe among so many options, ensuring it meets standards in both the steel pipe and the plastic coating? Today, we'll introduce three aspects to help you judge the quality of plastic-coated steel pipes.
1. Steel Pipes:
(1) Seamless, verifiable in well-lit areas.
(2) Excellent pressure resistance, not prone to deformation.
(3) Strong mechanical properties; will not break during the expansion test.
(4) Warranty certificates and inspection reports for fittings are provided.
(5) Free of burrs and other foreign matter; interior wall is clean and smooth.
(6) Steel pipes utilize high-quality carbon steel free of impurities, ensuring good hygiene.
2. Plastic Coating:
(1) Smooth finish with meticulous craftsmanship, free of burrs.
(2) The internal electrostatic coating process uses electrostatic attraction to adhere epoxy resin powder to the inner and outer walls of steel pipes, ensuring strength, high sanitation level, and being non-toxic and pollution-free.
(3) The exterior plastic coating with polyethylene layer features a shiny appearance, excellent adhesion, hardness, wear resistance, and smoothness. It is capable of withstanding low temperatures and preventing corrosion.
(4) Odorless, free of刺激性 odors.
3. Compliance Level:
(1) No warnings issued during eddy current testing.
(2) High-pressure resistance, no signs of detachment.
(3) Remains tightly attached after years.
