Seamless steel pipe plays an extremely important role in some fields. Due to the particularity of material selection, the production material needs to have greater density. The greater the density, the better the quality, seamless steel pipe after high pressure pressing, will make the whole with higher safety.
Hollow section, can be a large amount of fluid transport, compared with the round pipe and other solid steel, the bending and torsional strength of the same case, lighter weight, seamless steel pipe has become more economic section steel, manufacturing structural parts, mechanical parts have been widely used.
High pressure seamless pipe is a form of seamless steel pipe. The manufacturing method is the same as seamless steel pipe, but the steel used in the manufacturing of steel pipe, but has a particularly strict requirements. Production technology according to the difference in the use of temperature, divided into boiler tube, high-pressure boiler tube.
High pressure seamless pipe can be used normally in the ambient temperature < 450℃, domestic pipe no. 10, no. 20 carbon bonded steel hot rolled pipe, cold drawn pipe manufacturing.
The use conditions of high pressure seamless tube are mostly high temperature/high pressure. Under the action of high temperature flue gas and water vapor, oxidation and corrosion occur. Therefore, high pressure seamless tube is required to have stronger lasting strength, high oxidation corrosion resistance and organizational stability.
Whether seamless steel pipe, or high pressure seamless steel pipe, or other steel pipe, or all kinds of conventional weapons in the indispensable materials (gun barrel, barrel) must use steel pipe manufacturing.
