Product Introduction
D3848 low temperature fiberglass reinforced plastic
low temperature fiberglass reinforced plastic is a special low-temperature insulation epoxy glass steel pipe material for -196℃. It is made of electrician's alkali-free glass fiber cloth impregnated with epoxy resin and baked by hot rolling.
Application
The mechanical strength is high, and the heat resistance grade is F grade, which is suitable for demanding low-temperature equipment, air separation equipment and tank trucks.
Instructions
1) The properties of laminated pipes are different from those of metal, so they should be processed according to JB/Z 141.
2) Due to the low thermal conductivity of the laminated tube, a small feed rate and high cutting speed should be used during machining.
3) After the laminated pipe is processed, it is easy to absorb moisture. It is best to dip-coated insulating paint for moisture-proof treatment.
4) Dust and odor are easily generated during mechanical processing of laminated pipes, so ventilation and dust removal and labor protection of workers should be strengthened.
5) It is best to use dry processing for laminated pipes, because the wet method (cooling with water) can easily change its dielectric properties and affect its use.
6) Store in the original package in a dry, cool, ventilated room or under a shed that is strictly forbidden to smoke or fire. The storage period is twelve months from the date of leaving the factory.
