Double flat-wall steel-plastic composite drainage pipes are made of strips wound around a pipe forming machine and welded into pipes. The welding technology adopts internationally advanced double-layer welding and staggered seam welding technology to overcome the unreliability of single-layer welding. At the same time, it more effectively avoids the possibility of simultaneous radial cracking of the weld.
Double flat-wall steel-plastic composite drainage pipes can be green and environmentally friendly during the manufacturing, use and recycling processes. First of all, no waste water, gas and waste materials are generated during its production and manufacturing process, and there is no pollution to the environment required for manufacturing cement pipes. The production process of cement materials and the manufacturing process of cement pipes themselves seriously pollute the environment and have become the focus of environmental protection departments. Secondly, waste plastic pipes can be recycled and reused. When it is burned, only carbon dioxide and water vapor are produced, and no other harmful gases are emitted.
