Description of Seamless Steel Pipe
AISI/SAE 4330VMOD
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: 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
- The price range of raw material resin is about 10000/ tons to 60000/ tons.
- Q: FRP acceptance standard
- Perform hydrostatic test. In order to comprehensively check the installation quality of pipes, the pressure test shall be carried out according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipe works, and the allowable seepage water quantity shall be carried out according to the standards of the steel pipe.
- Q: Is there any ventilation duct made of glass fibre reinforced plastic in Baotou?
- Fiberglass pipeacid and organic glass steel fan shell with acid and alkali corrosion resistance, long service life, is mainly used in chemical, textile, printing, metallurgy, underground facilities for discharging corrosive gas places.
- Q: How is FRP ventilation pipe made?
- Coating moldingOn the surface of the mold, a transparent glass paper is fixed on the surface of the bread. When it is fixed, it is coated with a resin coating which has been adjusted. It should be even and not exposed. Then apply a layer of glass cloth and then coat with a resin coating. Each coated with a layer of resin is deposited a layer of glass cloth. The cloth lap to stagger and scraping, the outermost layer of ruibu glass surface should be coated with a layer of resin coating. After reaching the required thickness, and then deposited on the outer surface of the glass paper flatten the light pressure.
- Q: There is a gap between the new glass fiber reinforced plastic pipe and its through wall. How can the plug be prevented from leaking through the cracks around the pipe?
- Through wall holes, made of other materials, wall fittings, ship wall fittings and glass fibre reinforced plastic pipes, flanges or other forms of connections are used, which may be referred to the application of the components of the ship piping;
- 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: Who knows, how is the glass reinforced septic tank connected with the municipal pipe?
- If a glass fiber reinforced plastic outlet pipe is reserved, a new sewage inspection well is installed at the pipe end, and then a sewage pipe is installed to connect the reserved manhole of the municipal sewage pipe.
- Q: Slurry circulation glass fiber reinforced plastic pipe
- Slurry circulation glass fiber reinforced plastic pipe anti fouling and anti boring. Unsaturated polyester resin pipe surface clean and smooth, the special media will not be defiled rot fungi and other organisms have, for example, steel, cast iron or steel reinforced concrete pipes, the surface is easily attached and difficult to remove microbial decay, resulting in increased roughness, reduce cross section. The glass fiber reinforced plastic pipeline will not produce microorganisms in the case of light avoidance, so it is pollution-free and long-term clean.
- Q: What is the compressive strength of all kinds of FRP materials?
- Anti fouling and anti moth: unsaturated polyester resin surface clean and smooth, will not be ocean or sewage in the shellfish, fungi and other microorganisms stained, moth, so as to increase roughness, reduce water cross section, increase maintenance costs. FRP pipes are free from these pollution and are clean for a long time. At the same time, because of its smooth inner wall and excellent corrosion resistance, it will not cause scale and microbial growth, effectively guarantee water quality and maintain the stability of water resistance. But the traditional pipe still exist after water resistance increases and the surface fouling phenomenon.
