How much is a glass fiber reinforced plastic sand pipe socket pipe fitting?
Compared with the traditional pipe, it has excellent chemical resistance. It can resist acid, alkali, salt, oxidant, organic solvent, various kinds of grease, sewage and so on. Its lining is made of corrosion resistant and excellent resin as raw material, so no corrosion protection is needed. And after long-term use, no fouling, will not be contaminated by micro-organisms and debris deposition in the sewage, so as to increase the roughness rate and reduce the water cross section or plug the pipeline. Because the damage rate of glass fiber reinforced sand pipe is more than 4 times the working pressure, the safety factor is designed with enough safety factor.
Glass reinforced plastic sand pipe can increase rigidity by adding sand layer to the middle layer of pipe wall, which can meet any reasonable rigidity requirement of users. Another advantage of gfrpmp stiffness is bending deformation ability is very strong, for example, glass steel 5000Pa stiffness of sand in deformation of 20% cases, no delamination damage, and after unloading can restore the concrete pipe due to large deformation may be unable to bear have broken gfrpmp ring 150MPa ~ to the apparent flexural strength 450MPa, tensile and compressive and flexural strength of the concrete pipe were borne by steel and concrete, the apparent flexural strength is still far below the gfrpmp, only 8.5% ~ gfrpmp 26%. Generally, the service life of the drained glass fiber reinforced plastic sand pipe can be more than 50 years, and it is more than 2 times that of reinforced concrete pipes and other drainage pipes.
Gfrpmp light material, with the diameter of the pipe with pressure gfrpmp weight is 1/15 ~ 1/10 concrete pipe, resulting in transportation, lifting and lightweight, easy to install, laying pipes in drainage construction rectification, ensure the reliability of the pipeline axis and elevation positioning accuracy and construction. The drainage pipe interface with socket type "O" - type double seal ring connection, flexible joint tensile performance is better than that of concrete, so the soft mud foundation adaptability. The cost of pipe foundation treatment is greatly reduced compared with that of concrete pipe, so it is not necessary to install steel mould, lashing steel bar and pouring concrete as the concrete pipe, thus reducing the construction labor intensity and shortening the construction period [2].
