Description of Seamless Steel Pipe

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:Galvanized steel sheet and inorganic glass fibre reinforced plastic pipe are calculated according to this norm or norm
According to the project of quota valuation mode, input the actual quantity according to the quota item number, the following materials will automatically adjust the quota quota project, has been considering material wastage, when engineering calculation does not need additional.
Q:What qualifications do FRP pipes need to export to Australia?
Need to comply with the local certification standards or international certification standards certification system
Q:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?
This depends on the size of the pipe diameter, the greater the diameter, the thicker the wall.
Q:Why FRP pipes for outdoor waste gas treatment equipment are selected?
Therefore, the outdoor waste gas treatment equipment is usually made of glass fiber reinforced plastic.
Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?
Both have their merits, but it depends on their choice!
Q:What are the standards for FRP pipes?
To install FRP pipes, first check the radial deflection of the GRP pipe. In accordance with the requirements of the specification, the FRP pipe shall be tested within 24 hours after the completion of the installation to test whether the initial radial deflection of the pipe installed is deformed and whether the pipe has occurred in the case of bulge, flat and other mutations.
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:What kind of material is the pipe of the pipe that installs the pressure transmitter of GRP conduit? Is it fiberglass or carbon steel?
This depends on what your medium is, the general food industry requires stainless steel, but the medium contains acidic substances, stainless steel is better than FRP corrosion resistance
Q:Can FRP pipes be used in heating pipes?
Glass steel pipe road does not belong to common heating pipe material.Heating pipe requirements are solid, high temperature, pressure, easy connection, convenient construction.Usually, heating pipes are made of steel and materials are more common.
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.
