insulating tube
The glass flake wrapped epoxy anticorrosive steel pipe adopts a two-component normal temperature curable coating and is made of glass flake cloth as reinforcing coating on the surface of the steel pipe. The glass flake wrapped epoxy anticorrosive steel pipe can be used for anticorrosion of the outer wall of buried or underwater oil, gas, water and heat pipelines, as well as anticorrosion of various steel structures, docks, ships, sluices, gas storage tanks, petrochemical equipment and leakage prevention of sewage tanks, roof waterproof layers and basement concrete layers. Glass flake wrapped epoxy anticorrosive steel pipe is used together with glass fiber cloth to form a reinforced or extra-reinforced coating with excellent anticorrosive performance. * Glass fiber reinforced plastic insulation pipes are glass fiber reinforced plastic products with many uses. With the continuous development of FRP composite molding technology, FRP products have been widely used in various fields. FRP products have the advantages of light weight, high strength, corrosion resistance, long service life, flame retardance, high temperature resistance and various product forms. Therefore, various industries have gradually increased the use of FRP products, which puts forward higher requirements on the mechanical properties and molding process of FRP products. The molding process of FRP determines the shape, performance and application prospect of its products. The mechanical properties of FRP determine whether its products can have wider application space in industries with higher mechanical properties. Glass fiber reinforced plastic square pipes can replace some metal pipes used in industrial and civil fields such as central air conditioners and chemical plants.
insulating tube
The winding thin-wall steel yarn insulation pipe can effectively prevent the corrosion of the working steel pipe and prolong its service life. The pipe port shall be sealed with polyethylene film or three layers of PE cold tape to prevent moisture from entering before installation or water from entering during construction. Under 350 ℃, centrifugal glass wool is an excellent thermal insulation material with light weight and stable geometry. It adopts multi-layer staggered wrapping, effectively reduces heat loss, and controls the surface measures of the jacket to prevent the generation of cold bridges, thus ensuring the temperature control of the anticorrosion coating of the jacket.

The difference between the two outer sheaths is one wrapped glass cloth and one wrapped yarn. One hand and one machine. This is also a kind of progressive mechanical winding, which uses the process of making glass steel pipe on the outer sheath of polyurethane insulation pipe. Although the cost has increased, its process and product performance are relatively easy to control, eliminating the unstable performance of the previous manual products and backward process. It is worth learning from.
