FAQ

Can FRP pipes be used in heating pipes?
FRP pipes are generally not used in heating pipes, because the use temperature of FRP pipes is limited, as detailed below:1. universal unsaturated polyester FRP can only be used for less than or equal to 60 degrees (HG/T20696-1999)2. bisphenol A unsaturated polyester FRP can only be used for less than or equal to 100 degrees HG/T20696-1999)3. vinyl unsaturated polyester glass fiber can only be used for less than or equal to 120 degrees HG/T20696-1999)4. epoxy FRP can be used for less than or equal to 90 degrees HG/T20696-1999)5. glass fiber reinforced plastic sand holding pipes can only be used for less than or equal to 50 degrees (GB/T21238-2007)
FRP pipe price
Glass fiber reinforced plastic pipeline is a kind of light, high strength and corrosion resistant nonmetal pipe. It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer. The pipe wall structure reasonable and advanced, can give full play to the role of material, to meet the premise of use strength, improve the rigidity, ensure the stability and reliability of the product. Gfrpmp for its excellent chemical corrosion resistance, high strength and light weight, no scaling, strong shock resistance, and ordinary steel compared with long service life, low cost, quick installation, safe and reliable, accepted by the majority of users.
What kind of material does glass steel ship honeycomb board use?
Is an aluminum honeycomb core, with hexagonal type 3003 aluminum honeycomb core, aluminum foil thickness 0.04~0.06mm, length 5~6mm, the roll forming technology to complete the front and back skin forming, automatic folding machine, front and back skin in the mounting side tightly bite.
What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe? What kind of material is good?
Sand tube is more brittle, gfrpmp is relative to the glass tube can be called pure glass tube, glass tube is not with quartz sand, the two pipes generally used in different areas, the pure glass pipe can be used in most areas, but the sand tube is generally only used in the political field, especially is the large diameter sand tube.
What are the advantages of FRP pipes?
The relative density is between 1.5~2.0 and only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, while the specific strength can be compared with that of advanced alloy steel.
Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
When the length and width of glass fiber mesh are not enough, the method of lap joint must be adopted to improve the tangential bearing capacity of the joint, so as to effectively overcome the radial tensile stress, bending force and bending shear stress. The lap length of the glass fiber cloth at the joint is generally 50 to 100mm, and the joint of each glass fiber cloth should be at a certain distance from the adjacent joint. The longitudinal and transverse joints between adjacent layers shall be greater than 300mm, and the distance from the same seam shall not be less than 500mm.5) paste made of circular duct, glass cloth along the radial 45 degree angle to the direction of cut cloth; conical paste products, according to the fan-shaped cloth.
Uneven settlement of the foundation, can lead to glass fiber reinforced plastic underground water pipes burst, what is the principle?
Dislocation will cause the pipe to burst. The pressure is different, and the pipe will burst
Are FRP pipes still developing?
Glass steel complex (or perhaps not, but not absolutely continuous production mishap) manufacturing process, and China quality is not strictly controlled, low cost of pipeline as well as PVC and other engineering plastics, the high demand of the field of steel as reliable, is now used for chemical terminal treatment, city drainage etc..
