FRP Square Pipe (fiberglass reinforced plastic square pipe)

FRP Square Pipe (fiberglass reinforced plastic square pipe)

AWWA C950 requires the test to be carried out, with the resulting 50-year predicted value used in the pipes’ design. Lianzhong pipe is tested using the guidelines of ASTM D5365 “Long-Term Ring Bending Strain of Fiberglass Pipe” and meets both requirements.

    Product installation:

    Above ground GRP pipe installation:The support of GRP piping system is completely different from that of any other pipes and requires considerable attention. The modulus of elasticity of GRP pipe is low, in order to minimize the deflection, the proper spacing between racks must be selected. In order to minimize localized stress, the wide-band support should be used. In order to avoid the localized stress near the joint, the supporting point should be near the connection, all valves should be supported independently. Make sure the pipe standing support is firm to ensure the position of pipe standing from moving and to minimize the vibration of the vibrant part of pipe standing. The function of pipe standing or lift-standing should not be clip but conductivity to the pipes. For long pipeline, proper disposition of support spots is crucial to watch out for twisting moment in FRP pipe caused by the deformation of pipes which might result the break of pipes. Generally, for FRP pipeline, expansion joints may be unnecessary.


    We have been constantly improving the quality of our FRP Square Pipe (fiberglass reinforced plastic square pipe), thereby enhancing the brand image and the company's reputation. Our company provides a systematic education and training system for our employees, as well as a platform for career development.
