Seamless Steel Pipe Widely Used In The Manufacture Of Structural Parts And Mechanical Parts

Seamless steel pipe is a hollow section, the surrounding no seam of the long steel. Is made of steel ingot or solid tube through the perforated tube, and then by hot rolling, cold or cold made. Steel pipes have hollow sections, which are used as pipelines for conveying fluids, such as pipelines for the transportation of oil, natural gas, gas, water and certain solid materials.

Seamless steel pipe seamless steel pipe with a hollow section, a large number of pipes used for conveying fluid, such as the transmission of oil, natural gas, gas, water and some solid materials such as pipeline. Steel pipe and round steel and other solid steel compared to the same bending strength, the weight is light, is an economic section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle Such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel, steel and other steel scaffolding and other steel parts used in the construction of ring parts can improve the utilization of materials, simplify the manufacturing process, saving materials and processing time, such as rolling bearing rings. Steel pipe or a variety of conventional weapons indispensable materials, barrels, barrels and so on to steel to manufacture. Steel pipe by cross-sectional area of the shape can be divided into tube and shaped tube. As the circumference of the same conditions, the largest circular area, with a circular tube can transport more fluid. In addition, the ring cross section in the internal or external radial pressure, the force is more uniform, so the vast majority of steel pipe is a tube.

However, the tube also has some limitations, such as in the plane under the conditions of bending, the tube is not as good as the square tube bending strength, some agricultural machinery skeleton, steel and wood furniture on the commonly used side, rectangular tube. According to different purposes also need to have other cross-shaped shaped steel pipe.

Seamless steel pipe is widely used. General use of seamless steel pipe from the ordinary carbon structural steel, low alloy structural steel or alloy structural steel rolling, the largest output, mainly used for conveying fluid pipe or structural parts. .2, according to the use of different sub-three supply: a, according to chemical composition and mechanical properties of supply; b, according to the mechanical performance supply; c, according to the hydraulic test supply. According to a, b class supply of steel, such as for the use of liquid pressure, but also for water pressure test. 3, the special purpose of the seamless pipe with a seamless pipe, geological seamless steel pipe and seamless steel pipe and so on.
