Products brief introduction
Alloy tube with a hollow cross-section, for a large number of pipes conveying fluid, such as the transportation of oil, natural gas, coal gas,
water and some solid materials pipeline
Compared to solid steel alloy steel tubes and round steel in flexural torsional strength the same, lighter, alloy
steel tube is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe,
automotive transmissionshafts, bicycle frames and construction used in steel scaffolding
