Cold-rolled seamless pipe (GB3639-2000) is a cold-drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment
The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel pipe. Seamless steel pipes are divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes due to their different manufacturing processes.

How to distinguish hot rolled and cold rolled seamless Cold rolled (drawn)seamless steel pipe:. Cold rolled seamless tube is a seamless steel tube for high dimensional accuracy and good surface finish.Cold rolled seamless pipe in addition to include the general steel,low and medium pressure boiler tube,high-pressure boiler tubes,alloy steel pipe,stainless steel pipe and oil cracking tube,also includes carbon thin wall steel pipe,alloy thin wall
Hot-rolled seamless steel pipes and cold-rolled seamless steel pipes are formed by the process of steel or steel plate, they have a great impact on the microstructure and properties of steel, the rolling mill is mainly hot-rolled, cold-rolled only for the production of small steel and sheet. Description:Standard ASTM A106, ASTM A53, API 5L Gr.B, DIN17175, etc Material ASTM A106B, ASTM A53B How to make seamless pipe(seamless pipe process)?, Hot Cold rolled steel surface quality, appearance, dimensional accuracy better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor. Hot-rolled seamless steel pipe production base deformation process can be summarized as three stages:perforation, extension and finishing. Seamless Line Pipe,Cold Drawn Seamless Pipe,Hot Rolled Cold Drawn Steel PipeWe can classify the seamless steel pipes as cold drawn seamless pipe and hot rolled seamless pipe due to the producing process.It is widely used in water, oil and gas transfer, ship-building, chemical fertilizer equipment etc Hot Rolled Steel PipeThe hot rolled steel pipe (hot rolled seamless tube) is manufactured through automatic continuous pipe rolling mills.
CSPG is one of the seamless steel pipe manufacturers and suppliers in China, we mainly offer steel pipe, carbo steel pipe, seamless pipe, seamless steel pipe, hot rolled steel pipe, cold drawn steel pipe, seamless carbon steel pipe, spiral steel pipe, welded carbon steel pipe, lsaw steel pipe, erw steel pipe, hfw steel pipe, oil casing pipe, line pipe, pile pipe, anticorrosion pipe, etc Seamless Steel Pipe,Seamless Steel Tube,Hot-Rolled,Cold-Drawn3. According to different manufacturing methods, there are hot-rolled pipe, cold-rolled pipe, cold drawn pipe and extruded pipe. Hot-rolled seamless steel tube is often produced on the automatic pipe mill. In order to get seamless steel pipes with smaller dimension and higher quality, we usually adopt cold drawing method or the combination of [Hot Item] Cold Drawn Seamless Steel Tube for BoilerChina Cold Drawn Seamless Steel Tube for Boiler, Find details about China Seamless Pipe, Steel Pipe from Cold Drawn Seamless Steel Tube for Boiler - Liaocheng Rushun Import & Export Co., Ltd.
