Fluid Steel Pipe

GB/T8163 Fluid Seamless Pipe 1020 Fluid Seamless Pipe ASTM Fluid Seamless Pipe DIN Fluid Seamless Pipe

Fluid seamless steel pipe is a kind of steel pipe used for fluid transportation.

Differences between structural seamless steel pipe and fluid seamless steel pipe. This standard is applicable to seamless steel pipe for general structure and mechanical structure, and the fluid seamless steel pipe standard is applicable to general seamless steel pipe for fluid transportation. Its main difference from the structural seamless steel pipe is that the fluid seamless steel pipe is subject to hydraulic test one by one or ultrasonic, eddy current and magnetic flux leakage testing. Therefore, the fluid seamless steel pipe should be used in the standard selection of penstock steel pipe.

Fluid seamless steel pipe is a kind of pipe with hollow section and no weld from beginning to end. The steel pipe has a hollow section, which is widely used as a pipe to transport oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter when its bending and torsional strength is the same. It is a kind of economic section steel, widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Manufacturing annular parts with steel pipes can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing rings, jack sleeves, etc., which have been widely manufactured with steel pipes. Steel pipe is also an indispensable material for various conventional weapons. Gun barrel and barrel should be made of steel pipe. The steel pipe can be divided into round pipe and special-shaped pipe according to the shape of cross section area. Since the circle area is the largest under the condition of equal circumference, more fluid can be transported with circular tubes. 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.

① Generally, the temperature of boiler tubes is below 450 ℃, and domestic tubes are mainly made of No. 10 and No. 20 carbon bonded steel hot-rolled tubes or cold drawn tubes.

② High pressure boiler tubes are often used in high temperature and high pressure conditions. Under the action of high-temperature flue gas and water vapor, the tubes will be oxidized and corroded. The steel pipe is required to have high lasting strength, high oxidation and corrosion resistance, and good organizational stability.

(2) Purpose:

① General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes, arch brick tubes, etc.

② High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam pipes, etc. of high pressure and ultra-high pressure boilers.
