Tianjin TEDA Hongye Steel Trade Co., Ltd.: seamless seamless steel pipe, large diameter seamless steel pipe, seamless steel tubes of small diameter, thick-walled seamless steel tubes, thin-walled seamless steel pipe, large diameter thin-walled seamless steel pipe, large diameter thick-walled seamless steel pipe, seamless steel tubes of small diameter thin-walled, small diameter thick-walled seamless steel pipe. 
 Seamless is a kind of hollow cross-section, no seams around the circle, square, rectangular steel. Seamless steel pipe or solid steel ingot is made of the capillary tube through the hole, then through the hot-rolled, cold rolled or cold call is made. Seamless steel pipe with a hollow cross-section, a large number of pipes for conveying fluids, such as steel and solid steel round bar compared to the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding. 
 Seamless Overview: 
 Specifications of seamless steel pipe with wall thickness mm diameter * in number. Hot-rolled and cold rolled seamless steel pipe points (dial) types of seamless steel pipe. Hot-rolled seamless steel tube sub generally low, and medium pressure boiler pipe, high pressure boiler steel pipes, steel pipes, stainless steel pipe, oil cracking tubes, steel and other steel and other geological. Cold-rolled (allocated) Subject to sub-general seamless steel pipe, low and medium pressure boiler pipe, high pressure boiler steel pipes, steel pipes, stainless steel pipe, oil cracking pipe, other pipe, but also including thin-walled carbon steel, alloy steel thin-walled, thin-walled stainless steel, special steel pipe. Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, can be cold-rolled seamless steel pipe diameter to 6mm, wall thickness to 0.25mm, thin-walled tube diameter can be less than 0.25mm to 5mm thickness , cold than hot-rolled high dimensional accuracy.
