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

The seamless tube is a round, square, rectangular steel with a hollow section and no seams around it. Seamless steel pipe is made of steel ingot or solid tube through the perforated tube, and then made by hot rolling, cold or cold. Seamless steel pipe with a hollow section, a large number of pipes used for conveying fluid, steel and round steel and other solid steel compared to the same flexural strength, the weight is light, is an economic section of steel, widely used in manufacturing structure Pieces and mechanical parts, such as oil drill pipe, car drive shaft, bicycle frame and steel scaffold for construction.

1. Seamless steel pipe for the manufacture of various low and medium pressure boilers, superheated steam pipes, boiling water pipes, water wall pipe and locomotive boiler with superheated steam pipe, large smoke pipe, small smoke pipe and arch brick. Hot-rolled or cold-rolled (welded) seamless steel tubes with high quality carbon structural steels. Mainly made with 10,20 steel, in addition to ensuring the chemical composition and mechanical properties to do water pressure test, curling, flaring, flattening and other tests. Hot-rolled to hot-rolled delivery, cold-rolled (dial) to heat treatment delivery. The inner diameter of the pipe is determined by the length of the outer diameter of the drill bit.

2. Seamless steel pipe by the sizing, into the cooling tower, through the water cooling, steel pipe after cooling, it is necessary to straighten. Steel pipe straightened by the conveyor belt sent to the metal testing machine (or water pressure test) for internal testing. If the steel pipe cracks, bubbles and other issues, will be detected. Shaanxi Huichuan sales of steel are from Laiwu Steel, Shougang, Baotou Steel, Handan Iron and Steel, smelting steel, Tangshan Iron and Steel, Jiuquan Iron and Steel, Laiwu Steel, Anyang Iron and Steel, Longgang Maanshan Iron and Steel and other quality assurance of steel, are in line with national standard The

3. Steel quality inspection, with paint spray on the number, specifications, production batch number. And hanging from the crane into the warehouse. In the same cross-sectional area under the conditions of structural steel pipe than the side, flat steel and what type of steel all-round bending ability, good rigidity, because the side, flat steel and various types of steel bending ability are very strong Direction, but the bending performance of steel pipe is not only no direction, and the unit quality of the strongest bending resistance.
