mental pipe Factory outlet hollow Grouting steel pipe for Construction

The inner and outer plastic-coated steel pipe is a steel-plastic composite pipe formed by melting a layer of organic matter with a thickness of 0.5 ~ 1.0mm on the inner wall of the steel pipe. It not only has the advantages of high strength, easy connection, and resistance to water impact of steel pipes. It also overcomes the shortcomings of corrosion, pollution, fouling of steel pipes, low strength of plastic pipes, and poor fire-fighting performance when exposed to water. The design life can reach 50 years. National standards and industry standards: GB/T5130-2010 and CJ/T120-2008, etc. Applicable environment: -40℃~300℃ Plastic coated steel pipes inside and outside are widely used in water supply and drainage systems in the construction industry, HVAC circulating water systems, petroleum and chemical pipelines, fire sprinkler systems, natural gas and gas transportation and other fields.
