FRP sewage pipe
FRP sewage pipes have the following characteristics:
1. It has excellent anti-corrosion performance, no need for cathode anti-corrosion protection and other anti-corrosion measures, and it will not cause secondary pollution to water or other media. The product has a long service life.
2. Light weight pipelines occupy only 1/4 of ductile iron pipes of the same specification and length, and 1/10 of cement pipes. Convenient transportation and installation, easy installation.
3, the length of a single pipeline is reduced to reduce pipeline joints, speed up the installation speed, and improve the quality of the entire pipeline.
4. The inner wall of the pipeline is smooth to reduce flow resistance, increase flow velocity and reduce energy consumption. Use the more advanced pipeline to transport the fluid with the same flow rate, which can increase the flow rate by about 10% compared with the same size steel pipe; it does not scale and does not reduce the flow rate for long-term use.
5. Corrosion-resistant quick joint is adopted. The joint adopts double "O" type rubber sealing ring for socket connection. Convenient installation, sealing, and corrosion resistance. The joint can arbitrarily adjust the characteristics of the glass fiber reinforced plastic sewage pipe within the range of 3 °.

| Brief introduction: FRP pipeline process detailed description and its basic characteristics I. FRP pipeline process detailed description: 1. FRP pipeline preparation process (1) Equipment commissioning. First, carefully check whether the equipment is running and the working part is normal, especially check whether the resin-curing agent two-component pump is clogged, and whether the ratio between them meets the design requirements; ensure that the equipment such as lining, winding, trimming, demoulding, etc. (2) Clean the mold. It is required that the surface of the mold is free of pits, dust, sundries and other attachments. The surface of the mold should be smooth, and if there is a problem, it should be repaired and maintained in a timely manner; (3) polyester film. In order to facilitate the demoulding of the pipeline, the surface of the mold should be covered with a layer of polyester film, the overlap width of the film is 1 to 2㎝, and the thickness is between 40um. It is required that the film is not broken, no wrinkles, and both sides are smooth and clean. The quality of the film products meets the requirements of GB13950-1992. 2. Lining process (1) Preparation of lining resin. Press ... [ detailed ] |
