The flexible socket-type coated steel pipe is made by a special expansion process, using high-quality steel pipes as the base material. It adopts advanced epoxy resin or polyethylene anti-corrosion coatings to meet pipeline corrosion prevention requirements. The anti-corrosion coating has a good inhibitory effect on microbial corrosion and bacterial acid corrosion within the drainage pipe under alternating conditions of full flow and low flow. Our company is a standard participant in the China Iron and Steel Industry Association for the design of socket-type anti-corrosion steel pipes for water transportation. The structural performance uses a double rubber ring seal, ensuring the pressure-bearing capacity and testing requirements at the pipe ends. The single water pressure can reach over 30 kgf/cm².

Production specifications: φ426mm-φ1620mm.
