Wherever you look, seamless steel tubes are an integral part of modern life. Today, the oil and gas industry, the construction and mechanical engineering industries, and automotive manufacturers demand ever better tubes made of higher steel grades, with closer tolerances and new dimensions. Seamless Pipe Hot Rolling Continuous Rolled Carbon Steel Seamless Pipe Hot Rolling Continuous Rolled Carbon Steel Pipe. Size:OD:32-610mm, Thick:3-50mm Material:Gr.B, X42-X70, ST37,ST37.2,etc. Standard:API 5L,API 5CT,ASTM
Seamless steel tube:The seamless steel tube is perforated with steel ingots or solid billets, and then hot rolled, cold rolled or cold drawn. The specifications of seamless steel pipes are eed in mm outer diameter * wall thickness. Seamless steel pipes can be divided into Seamless Steel Pipe,Seamless Steel Tube,Hot-Rolled,Cold 3. 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 Seamless pipe, mild steel and stainless steel seamless pipePQF (Premium Quality Finishing Mill) continuous rolling is the most advanced technology for producing hot rolled seamless steel pipe of modern industry. It creates high quality seamless steel pipe efficiently, even for high alloy pipe and light wall pipe. Size Range:2 (60.3mm) to 20 (508mm)
The pierced billet or hollow shell is rollreduced in outside diameter and wall thickness. The rolled tube simultaneously burnished inside and outside by a reeling machine. The reeled tube is then sized by a sizing mill to the specified dimensions. From this step the tube goes through the straightener. This process completes the hot working of the tube. Sturdy, Stainless hot rolled seamless steel tube thick The hot rolled seamless steel tube thick wall you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements. With seamless welding quality, these hot rolled seamless steel tube thick wall are annealed with nitrogen protection and are polished with utter professionalism. These products are made of robust materials such as carbon steel, stainless Tube Billets For Precision And Cold Drawn Seamless Steel PipeIn the production of hot-rolled seamless steel tubes, the surface condition of the tube Billets must first be strictly checked. The outer surface of the tube Billets is not allowed to have crusting, cracks, cracks, grooves, folds, dents, ears, pores, and hemp. Defects such as spots, blisters and non-metallic inclusions.

Ingot casting can destroy tissue, grain refinement of steel and eliminate defects microstructure, so that the steel dense tissue mechanical properties are improved.
