Compare Chinese FRP and GRP pipe factories for filament-wound, centrifugal-cast and custom piping systems by pressure, stiffness, liner and standards.
| Field | Typical range | Sourcing note |
|---|---|---|
| Service | Water / sewer / chemical / seawater / FGD | Provide fluid, concentration and temperature. |
| Design class | Pressure, stiffness, vacuum and burial case | State transient loads and design life. |
| Construction | Liner + structural wall + exterior layer | Request laminate sequence and resin system. |
| Joint | Bell-spigot / butt-wrap / flange / mechanical | Include site method and gasket requirements. |
| Standards | ASTM / ISO / EN / GB / project code | Define the governing edition and hierarchy. |
| Testing | Hydrostatic / stiffness / hardness / visual / dimensions | Agree witness points before production. |
Chinese FRP pipe manufacturers cover water transmission, sewer, chemical process, seawater, flue-gas and industrial duct applications. Filament winding is common for pressure and chemical systems, while other processes serve drainage and special geometries. Diameter alone is not a sufficient buying specification: pressure class, ring stiffness, vacuum, temperature, chemical media, liner, burial condition, joint type and design life must be considered together.
Relevant standards may include ASTM D2992 and D2996, ISO 10928, EN 1796, EN 14364, GB/T 21238 and project-specific piping codes. These documents are not automatically equivalent. A supplier should state the design basis, regression data, laminate sequence and safety factors behind a proposed class. Chemical service also requires confirmation of the corrosion barrier, resin manufacturer guidance and any temperature derating.
GetFRP screens the public network for process, diameter range, winding control, joint capability, testing equipment and documented export experience. Buyers can inspect company profiles first and use a controlled RFQ once the engineering scope is coherent. For orders, inspection can cover dimensions, hardness, visual condition, hydrostatic testing where applicable, laminate records, fittings, trial assembly, packing saddles and marking so that pipe arriving at site can be traced to the accepted design.
Every card is an explicit supplier-product relationship. Verification applies to the recorded capability and evidence state, not a blanket certification of every specification.
