Tianjin Teda Hongye Steel Trade Co., Ltd. Production: seamless steel pipe, seamless steel pipe of large diameter, small diameter seamless steel pipe, thick-walled seamless steel tubes, thin-walled seamless steel pipe 
 Seamless steel pipe is a hollow sections, peripheral joints round, square, rectangular steel. Seamless steel pipe perforation made of steel ingot or solid tube capillary, and then allocated by the hot-rolled, cold rolled or cold made. Seamless steel tubes with hollow cross-section, a large number of solid s steel pipes, steel round bar used for the transmission fluid 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 steel pipe Overview: the specifications of seamless steel pipe with wall thickness mm OD *. Seamless steel pipe divided into hot-rolled and cold-rolled (reversal of) two types of seamless steel pipe. Divided into general steel pipe hot-rolled seamless steel pipe, low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipe, stainless steel, petroleum cracking tubes, geological steel pipe and other pipe and so on. Cold-rolled seamless steel pipe in addition to the points (reversal) general steel pipes, low and medium pressure boiler pipe, high-pressure boiler steel pipes, alloy steel pipe, stainless steel, petroleum cracking tubes, other steel pipes, carbon steel tubes, alloy steel tubes stainless steel tubes and shaped steel tubes. Generally greater than the hot-rolled seamless pipe diameter 32mm, wall thickness 2.5-75mm, rolled seamless steel pipe outside diameter to 6mm wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm wall thickness less than 0.25mm , cold than hot-rolled dimensional accuracy. 
 Seamless steel tube material :: 10 #, 20 #, 35 #, 45 #, 20G, 40Cr, 20Gr, 16Mn-45Mn, 27SiMn, Cr5Mo, 12CrMo (T12), 12Cr1MoV, 12Cr1MoVG, 10CrMo910, 15CrMo, 35CrMo, 40CrMo
