Fire-resistant coated steel pipe

Plastic-coated steel pipes exhibit excellent corrosion resistance and relatively low frictional resistance. Epoxy resin-coated steel pipes are suitable for conveying media such as water supply and drainage, seawater, warm water, oil, and gas; PVC-coated steel pipes are suitable for conveying media such as drainage water, seawater, oil, and gas. Connection options include: threaded connection (DN15–DN100), grooved connection (DN65–DN400), flange connection (applicable to any pipe diameter), welding, bimetallic connection, socket connection, pipe joint connection, and sealed connection.

 Product Features:

 Plastic-coated steel pipes are manufactured using PE (modified polyethylene) via hot-dip coating or EP (epoxy resin) for both inner and outer coatings, offering excellent corrosion resistance. The coatings themselves also exhibit superior electrical insulation properties, preventing electrochemical corrosion. These pipes feature low water absorption, high mechanical strength, and a low coefficient of friction, making them suitable for long-term service applications. Additionally, they effectively protect against damage caused by plant root systems and soil environmental stresses. Connection and maintenance are straightforward. Compliance standards: CJT120-2008 "Plastic-coated composite steel pipes for water supply"; GBT 5135.20—2010 "Plastic-coated steel pipes for fire protection".
