Product Description. Our Welded Steel Pipe with an annual installed capacity of 100,000 MT. HF-ERW pipes are made from hot rolled flat steel strip, formed into tubular shape and the longitudinal seam is welded by the application of mechanical squeezing of edges and heating the edges through High Frequency Electric Resistance applied by induction or conduction. API 5L ERW Steel Pipe, Seamless Steel Pipe, SSAW Steel Seamless Steel Pipe is a long steel with a hollow cross-section and no joints around it. Introduction to Practical Knowledge of Pipes (Part 1) Welded steel pipe, also known as welded pipe, is a steel pipe that is made by welding a steel plate or steel strip after crimping.
API 5L Pipe Specifications. API 5L Pipe have two product specification level, PSL1 and PSL2, and there are differences for the two levels in each grade. Manufacturing Types in Seamless, ERW, LSAW, SSAW, HSAW, DSAW. API 5L Pipe in Seamless Type inlcuding Hot Rolled Seamless and Cold Rold Seamless. Outer Diameter for this type normally under 24 inch. API 5L Seamless Steel Line Pipe in Gr B to X65, for Oil API 5L Seamless steel pipe production methods can be divided into:Hot-rolled seamless pipe, Cold drawn (rolled) pipe and tube, Thermal expansion pipe, Cold spinning tube and Squeeze tubes. Formation Seamless API steel pipes are made from a round steel billet while welded pies are made from a strip which is rolled and welded.

Shandong Jianlong Iron And Steel Co., Ltd. Was set up in 2009. We can supply seamless steel pipe, welded steel pipe, API pipe, square pipe, line pipe, special steel pipe, iron pipe, stainless steel pipe. Differences between Hot Rolled and Cold Rolled Seamless 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. ERW, SSAW, LSAW Welded Steel PipeERW steel pipe:high-frequency straight seam resistance welded pipe, using hot-rolled wide coil as the material, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, blocking and other processes, it has a shorter weld seam than the spiral, standard High precision, uniform wall thickness, good surface quality, and high-end benefits under pressure, but the
Cold rolled electric welded (CREW) tube is produced per ASTM A513 Type 2. CREW is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a narrower range of mechanical properties than A513 Type 1. Hot Rolled Seamless Steel Pipes/Tube Manufacturers Hot Rolled Seamless Steel Pipes & Tubes Manufacturers & Suppliers. We are a specialist producer and supplier of hot rolled seamless steel pipes and tubes in a wide range of grades and sizes. Hot rolled seamless pipes are manufactured mainly from steel ingots followed by processes such as piercing, hot rolling, and size reduction.
