Description of Seamless Steel Pipe
P91
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.
Features of Seamless Steel Pipe
High strength
High toughness
High hardenability
The cold deformation

- Q: Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
- 1) FRP reinforcement, length of rectangular duct is greater than 900mm, and the pipe length is more than 1250mm, should be strengthened. The reinforcement shall be made of bulk material (fiber reinforced plastic) and reinforced plate at the maximum stress, so as to increase the modulus of the section and increase the overall strength of the tube. FRP reinforcement can also be in the wind pipe production is completed, the treated metal or other corrosion resistant material for reinforcement, reinforcement and FRP as a whole, and with the same pipeline body cementitious material sealing gap2) hobas pipe surface thickness of the slurry to flatten the glass fiber mesh cloth texture is appropriate (see:). No dense air holes and grout leaks are allowed on the wall of the pipe to avoid the stress concentration under the bending tensile stress (positive air pressure) and the bending compressive stress (negative wind pressure).3) FRP pipe and flange corner should transition arc, transition radius to wall thickness of 0.8 ~ 1.2 times, improve the bearing capacity and the cantilever flange to avoid stress concentration. Fiberglass mesh shall be extended to the duct at the flange of the duct.
- Q: 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.
- Q: Is the installation of FRP pipes required qualification?
- Generally speaking, the glass steel pipe manufacturers will be installed for shipyard workers training, but if the shipyard did not ask, the training goal is to allow workers to master the skills to install, but they do not grant workers qualification certificate, but some shipyard will require workers engaged in installation with the installation qualification, so manufacturers will end in training workers to master confirmation the installation skills of workers, awarded the class approved qualification certificate. I don't know. Are you clear about that?.
- Q: CGCT what's the meaning of the GRP sand pipe?
- Glass reinforced plastic sand pipe is actually in the production of glass fiber reinforced plastic pipe, in the middle to increase a layer of sand layer, the purpose is to increase the rigidity of the pipeline.
- Q: What can be done to solve the leakage of FRP pipe?
- DN1800 FRP pipe pressure of 9 kilograms, the pressure is very high, crushed by stones, not repaired will certainly leak, the pressure pipe leakage is very bad, will be washed away the soil, spewing a few meters high water column.
- Q: What are the main materials used for steel pipes?
- General: steel duct (ordinary steel), galvanized plate (Bai Tie) wind pipe, stainless steel pipe, glass steel ventilation ventilation pipe, plastic pipe, composite pipe ventilation ventilation, ventilation pipe, sandwich insulation board rubberized cloth ventilation tube (such as mine, mine ventilation duct) plastic pipe; ventilation pipe by use of points: General: purification system air supply pipe, central air conditioning and ventilation pipe, industrial ventilation ventilation pipe, suction duct, environmental protection system for mine gas drainage pipe, mine ventilation pipe coating cloth duct; according to the shape: General: round, rectangular, spiral etc.;
- Q: How to install FRP pipe correctly
- Field bonding process is usually provided by glass fiber reinforced plastic manufacturers, if there is no way, I can provide some experience for reference, there is little information, experience only.
- Q: Would like to ask about the plastic lined steel pipe, steel pipe, glass steel skeleton, the advantages and disadvantages of each ceramic pipe, to know a friend told, very grateful!
- Steel skeleton pipe is not corrosion resistant, often used in drainage, easy to install, the price is almost the same as fiberglass, cheap inside there is no steel skeleton
- Q: The role of glass fiber reinforced plastic cooling towers
- Thermal power plants usually have cooling towers. Water heating, high pressure gas generated by promoting the steam turbine power generation, and the remaining gas cooling.
- Q: What is the elastic modulus of glass fiber reinforced plastic?
- If so, the modulus of elasticity is 72000MPa, and the glass is isotropic, so the modulus of elasticity in the three directions is the value.
