Selection criteria for large-diameter non-metallic pipes
Thread Content
For non-metallic pipes, the standards for pipes and fittings have not been updated for many years. What standards are currently being used for non-metallic pipes with large diameters of DN700 and above?
Currently, the selection criteria for non-metallic pipes with a large diameter of DN700 or more are primarily based on standards such as GB/T 21238-2007 \"Glass Fiber Reinforced Plastic Sand-Lined Pipes\" and CJ/T 114-2000 \"Continuous Fiber-Wound Glass Fiber Reinforced Plastic Pipes for Underground Use\", as well as other relevant industry standards. The specific standard to be chosen depends on the operating environment and requirements of the pipeline. .
Can FRP/PVC pipes and fittings now be made in sizes over DN600? The current standard is still version HG/T21636-1987, and it remains the current edition
