Description of Seamless Steel Pipe

Small spiral seam submerged arc welding pipe

Seamless steel pipe is a hollow section, no seams of strip steel. Is made from solid tube ingot or the perforation capillary, then through hot rolling and cold rolling or cold dial. Steel pipe has a hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines

Q:Where are the advantages of FRP pipes? Long life?
Heat resistant and frost resistantAt the temperature of -30 DEG C, it still has good toughness and high strength. It can be used for a long time in the range of -50, -80 degrees Celsius, and the resin with special formula can work at the temperature above 110 DEG C.
Q:Why more and more people choose FRP pipe?
The cost performance of FRP pipes is higher than that of PP, PVC, PE or concrete, and the strength, hardness and toughness of PP, PE and PVC are not as good as those of FRP pipes
Q:How to connect glass fiber reinforced plastic sand pipe?
Socket connection is one of the main connecting type of underground pipelines, the use of double "O" type sealing ring connection, the two sealing rings, the socket has pressure test mouth, the installation must be made up and mouth pressure test in the two ring between each interface can be arranged near side pressure test the test pressure, by design, water consumption is very small, the duration is 3 ~ 5min, with no leakage for qualified, ensure that each of the seal effect to ensure that the entire pipeline system overall pressure test success.
Q:Slurry circulation glass fiber reinforced plastic pipe
Slurry circulation glass fiber reinforced plastic pipeline has good corrosion resistance. FRP pipes are resistant to acid, alkaline, and non fluid erosion. In general, the service life of the steel pipe is 15 years, the cast iron pipe is 5 - 10 years, and the glass tube can be used for 50 years.
Q:What is the standard of flange coefficient for FRP ducts?
Negotiations did not consider, people reported flange you have to consider, 15% below have been used to see your negotiating skills, there is no standard specification! The above said I have used, and now I generally talk about n yuan / square meter, including the wind pipe, pipe fittings, flanges and valve components to connect the flange are included in
Q:How much is a glass fiber reinforced plastic sand pipe socket pipe fitting?
Glass reinforced plastic sand pipe can increase rigidity by adding sand layer to the middle layer of pipe wall, which can meet any reasonable rigidity requirement of users. Another advantage of gfrpmp stiffness is bending deformation ability is very strong, for example, glass steel 5000Pa stiffness of sand in deformation of 20% cases, no delamination damage, and after unloading can restore the concrete pipe due to large deformation may be unable to bear have broken gfrpmp ring 150MPa ~ to the apparent flexural strength 450MPa, tensile and compressive and flexural strength of the concrete pipe were borne by steel and concrete, the apparent flexural strength is still far below the gfrpmp, only 8.5% ~ gfrpmp 26%. Generally, the service life of the drained glass fiber reinforced plastic sand pipe can be more than 50 years, and it is more than 2 times that of reinforced concrete pipes and other drainage pipes.
Q:Glass fiber reinforced plastic GRE pipe broken hole how to repair and repair?
Resin selection of good points, the general also line, as well as accelerators, curing agents, high-quality glass fiber cloth.
Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe?
If the thickness of the pipe can meet the requirements of pressure, but can not meet the stiffness requirement, will choose to increase the thickness of sand to meet the stiffness (of course can not directly increase the sand thickness to meet the requirement of stiffness, but the cost is too high).
Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe? What kind of material is good?
Other fields such as chemical industry, the product is relatively high, generally aerial or ground, even if there is high pressure, bad high risk, so even high stiffness is thicker instead of sand, in general, not afraid of high investment, the use of pure glass tube, don't use the sand tube.
Q:What are the specifications of glass fibre reinforced plastic cable pipes? What are they?
FRP cable pipe is a new type of composite material, it mainly resin as adhesive, glass fiber as reinforcing agent, quartz sand as the supplementary material, formed by microcomputer control winding machine manufacturing, it has the strength of resistance to high pressure, weight, easy installation, safe and reliable, strong performance of insulation, corrosion can be anti corrosive the items, the anti parameter Water Leakage ability, but also has the advantages of long service life, can reach more than 50 years, because the FRP cable protection pipe set has various advantages of the industry, the performance has exceeded the same industry plastic pipe performance, it becomes popular industry engineering personnel.
