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:What are the differences between inorganic FRP pipes and plexiglass pipes, what are the advantages and disadvantages?
Fiberglass pipeacid: organic resin and glass fiber cloth hand pasting a small proportion of strength and long life advantages
Q:Glass fiber reinforced plastic sand pipe backfill 5m, how much kg pressure?
In general, glass steel pressure refers to the internal pressure, the conveying pressure of water, and you said the backfill produces is the external pressure, often say that the stiffness parameter.
Q:How can I replace the valve on the water supply pipe?
Steel flanges, three way pipe fittings and single disk connector is connected, immediately install three branch pipe valve, and will be closed fittings and valves at the bottom with concrete pier support, in order to timely restoration of water supply.
Q:What is the thickness of all types of FRP pipes?
DN200, DN150, DN100, DN80 pipe, polyurethane foam pad, 50mm thick shell, glass steel, thickness 3mm.
Q:How to open a DN300 port on the DN600 GRP pipe and install the DN300 gate?!
Do not know the road of glass steel flange have, if any to buy different materials of cast iron flanges or PVCU flange on the same material, the three way behind the pipeline branch, so that the material market has purchased (ABS buy buy in the small town is not easy), the construction is convenient. If it is a glass steel pipe, pipe end cannot change, can only be used to bond the glass steel material, the pipe bonded on the flange is an arc for a plane is bonded with a cast iron pipe flange suggestions. Because the FRP material and most of the plastic are not bonded.
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 kind of material are the flanges and valves on the GRP pipe?
Construction: glass fiber reinforced plastic can be threaded joints, easy to install, better quality, PVC generally glue adhesive, due to temperature problems, quality is difficult to ensure;
Q:Pipe installation of glass fibre reinforced plastic pipe
The slope of the pipeline shall be adjusted according to the requirements of the drawing. The adjustment method can be achieved by using the support to reach the slope requirement. The weld shall be located where it is convenient for inspection and observation.
Q:What's the price of fiberglass reinforced sand pipes?
This depends on the specific size of the caliber you want, how much thickness, specifically for you to quote. If you have any questions, you can talk to me privately.
Q:How long is the service life of glass fiber reinforced plastic pipes?
The glass fiber reinforced concrete grille is made of three kinds of polypropylene, polyvinyl chloride and ethylene propylene copolymer. The FRP grille is only half the size of the glass, saving transportation, unloading, mounting, and supporting the cost of the frame.
