Product features:
Designable materials:Because FRP products can be designed and made according to different use environment and special performance requirements, so as long as the selection of appropriate raw materials, basically can meet the performance requirements of different uses for the use of products.Therefore, FRP material is a kind of materials that can be designed.
Product advantages:
FRP pipes are light weight and high strength:The relative density is between 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even more than that of carbon steel, and the specific strength can be compared with that of advanced alloy steel. Therefore, in aviation, rockets, space vehicles, high pressure vessels and other products that need to reduce the weight of the application, have excellent results.The tensile, bending and compressive strength of some epoxy FRP can reach more than 400 MPa.
Product application:
Seawater desalination industry:GRP pipes due to its good corrosion resistance, is very suitable for use in the desalination industry.

Manufacturing Process:

Winding process:The designed parameters were input into the microcomputer, and after the lining solidified, The reciprocating winding of alkali - free twisted glass fiber was controlled by microcomputer until the layer thickness was reached.The outer protective layer with 100% resin content shall be applied according to the specified thickness.The resin content of the wound layer is generally around 35%, and its thickness depends on the combination of the strength and stiffness of the pipeline design.
Performance Standards:
AWWA:AWWA C950 is one of the most comprehensive product standards in existence for fiberglass pipe. This standard for pressure water applications has extensive require¬ments for pipe and joints, concentrating on quality control and
prototype qualification testing. Like ASTM standards, this is a product performance standard.Lianzhong pipe is designed to meet the performance requirements of this standard. AWWA has recently issued a new standards manual, M-45, which includes several chapters on the design and fabricate of GRP pipe for buried and aboveground installations.
