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: 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: Are FRP pipes still developing?
- Although high-end composites have all sorts of benefits, glass tubes can replace traditional plumbing materials, at least far away.
- Q: How to install FRP pipe correctly
- And glass fiber reinforced plastic parts (three, elbow, etc.) in general, the best way is on-site bonding, quality stability and convenience.
- Q: Glass fiber reinforced plastic pipeline to do anti-corrosion?
- Glass steel pipe does not need to do anti-corrosion treatment, the material itself is the biggest advantage of corrosion resistance
- Q: What are the differences between FRP pipes and sand pipes in their uses?
- Pressure more than 10 kg, generally do not clamp sand tube. Process tubes are mainly used in highly corrosive workplaces such as acids, alkalis, salt solutions, or high pressure pipes.
- Q: Who knows, how is the glass reinforced septic tank connected with the municipal pipe?
- Septic tank (Hu, F, NCH) is the treatment of nightsoil and to filter precipitation equipment. The principle is that the cured material decomposes at the bottom of the tank, and the upper hydration object flows into the pipeline to prevent the pipe from clogging and has enough time to hydrolyze the solidified object (such as excrement and urine). Tank (septic) refers to the division of living sewage sludge, and anaerobic digestion of sludge structure of small structures.
- Q: How many times can the temperature withstand of FRP winding pipes? What are the factors?!
- FRP coil pipe:(1) corrosion resistance: chemically inert material, excellent corrosion resistance, and can choose different corrosion resistant pipes according to the transmission medium.(2) strong mechanical strength: good water pressure resistance, good resistance to external pressure and impact strength, and piping and fittings can be designed according to the required pressure.(3) temperature adaptability: the use of temperature range: greater than -70 degrees Celsius, less than 250 degrees Celsius, under the freezing medium, the pipe is not split. (4) the resistance of the fluid is small: the pipe wall is smooth, the roughness coefficient is 0.0084, and the pipe diameter can be reduced under the same flow rate.(5) light weight, long life: light quality, convenient transportation, low construction cost, no maintenance, and the service life of more than 50 years.(6) maintain the water quality: non-toxic, conveying drinking water, can maintain long-term water quality sanitation.
- 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: What is the elastic modulus of glass fiber reinforced plastic?
- Glass fiber reinforced plastic is another name for glass fiber reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. Depending on the fiber used, glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastic (CFRP), boron fiber reinforced composite plastics and so on are classified. It is a kind of composite material made of glass fiber and its products (glass cloth, band, felt, yarn, etc.) as reinforcing material and synthetic resin as base material. Fiber reinforced composites are composed of reinforced fibers and matrix. Fiber (or whisker) diameter is very small, generally below 10 mu m, less defects and smaller, fracture strain of about 30/1000, is brittle material, easy to damage, fracture and corrosion. The matrix is much lower in strength and modulus than fiber, but it can withstand large strains, often with viscoelasticity and elasticity, and is a ductile material.
- Q: What are the posts of glass fiber reinforced plastic sand pipe and the corresponding occupational hazards and protection?
- Glass reinforced plastic underground sand pipe has long service life without operation and maintenance, which is the biggest advantage of this product. Since pipe jacking is an underground concealed project, its service life is undoubtedly the very important consideration of decision-makers. The service life of glass fiber reinforced plastic sand pipe jacking is more than 50 years, which is incomparable to the products such as steel pipe, concrete pipe and so on.
