American standard steel pipe is a kind of long steel with hollow section and no joint around. The steel pipe has hollow cross-section and is widely used for conveying fluid. American standard seamless steel pipe standard is such as pipeline for transporting oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when its bending and torsion strength is the same. It is a kind of economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. The use of steel pipe to make annular parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and working hours. For example, rolling bearing rings and Jack sleeves have been widely used in steel pipe manufacturing. Steel pipe is also an indispensable material for all kinds of conventional weapons. Gun barrel and barrel should be made of steel pipe. Steel pipe can be divided into round pipe and special-shaped pipe according to different cross-sectional area. Because the area of the circle is the largest under the condition of the same circumference, more fluid can be transported by the circular pipe. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform, so most steel pipes are round pipes.
Among American standard steel pipes, ASTM A53 gr. B General Purpose seamless steel pipe, ASTM A106 gr. B chamfered chamfered chamfered steel pipe, ASTM A333 - 40 ℃ - 101 ℃ low temperature seamless steel pipe, ASTM A179 seamless steel pipe for heat exchanger and condenser Length of steel pipe: 5.8m, 6m, 12m and up to 12m can be determined, and the length can be determined according to the needs of users.
The outer diameter of the product is 1 / 2 "- 28", 21.3-711.2mm, and the wall thickness is sch30, sch40, STD, XS, sch80, sch160, XXS, etc. the surface of seamless pipe can be treated with anti-corrosion treatment according to the requirements, with plastic pipe cap at both ends, chamfering as required, and commodity inspection can be conducted.
