◉ Product Details


Seamless Steel pipes with hollow sections are widely used as conduits for conveying fluids,
 such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as
 round steel, steel pipe has the same bending and torsional strength and is lighter in weight.
 It is a kind of economic section steel, widely used in the manufacture of structural parts and
 mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel
scaffolding used in construction.
