Description of Seamless Steel Pipe
ASTM A519 4140
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
Application of Seamless Steel Pipe
Screw drill tool

- Q: Mending method for glass fiber reinforced plastic pipe
- The method for mending and mending the glass fiber reinforced plastic pipe is hand paste, and the repairing steps are as follows:The stones must be taken away so that the pipes are restored to their original shape.Into the pipe, grinding first and lining the lining. If you can't get into the pipe, polish it from the outside, polish it to the lining, and then make a new lining.Reinforce the structure with a cloth.
- Q: The difference between GRP cable duct and PVC cable pipe
- Glass fiber reinforced plastic cable pipe is a kind of pipe made of resin as matrix, with continuous glass fiber and fabric as reinforcing material, and controlled by computer, winding process or pultrusion process.
- Q: What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe? What kind of material is good?
- Sand tube is more brittle, gfrpmp is relative to the glass tube can be called pure glass tube, glass tube is not with quartz sand, the two pipes generally used in different areas, the pure glass pipe can be used in most areas, but the sand tube is generally only used in the political field, especially is the large diameter sand tube.
- Q: What are the materials used in smoke exhaust pipes?
- In the production of the coal mine exhaust pipe is indispensable, in underground work, because from the ground, the air is not easy to reach, easy to accumulate large amounts of methane gas, these gases will need ventilation pipe timely transferred to the ground to prevent the explosion in the coal mine ventilation pipe, the material is generally iron and plastic.
- Q: What is the difference between glass tube, sand pipe and glass tube?
- The pipeline in the design according to the use of pressure, stiffness and other conditions to determine the need for sand, if the thickness of the pipe can satisfy the pressure requirements and can meet the requirement of stiffness, is generally not the sand.
- Q: What is the standard of flange coefficient for FRP ducts?
- Can be explained in this way, the flange width is generally 50, on both sides that is 100, flange thickness is calculated as two times the thickness of the pipe, or 200. The duct length is 2000 knots, and 200 is 2000 of the 10%
- 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!
- Plastic lined steel pipe of strong corrosion resistance, heavy quality, need to be made, on-site installation, if the size deviation cannot be installed. The price is more than 5 times more expensive than that of FRP
- Q: Why more and more people choose FRP pipe?
- And the price ratio of FRP pipe is not much cheaper, and although the hardness of concrete pipe although FRP pipe to be hard, but the toughness and tensile strength is poor, the pressure is not good, and the cost is expensive, because more and more people use glass steel, and the price is expensive, with longer life.
- Q: Is it possible to touch the water when the glass fiber reinforced plastic pipe is polished?
- Because the resin curing mechanism of FRP products is resin, resin agent, resin curing agent together to react, and release a lot of heat, this process does not affect the curing process because of a small amount of water and at the same time, if you have a little bit of water molecules would because of the large amount of heat emitted by evaporate, so does not affect the bonding of glass and steel that will not affect the glass steel pipe interface
- 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.
