Black steel pipes and tubes are cut and threaded to fit the job. Fittings for this type of pipe are of black malleable (soft) cast iron. They connect by screwing onto the threaded pipe, after applying a small amount of pipe joint compound on the threads. Larger diameter pipe is welded rather than threaded. Best ERW Welded Steel Pipe and Tubes, Spiral Welded Steel LASW WELDED STEEL PIPE, LASW Welded Steel Tube, with the production method of longitudinal welded arc welding. ERW Welded Steel Pipe is produced by electric resistance welding method, from raw material of hot rolled or cold rolled steel plate, steel coils. There is a straight weld seam on both inside and outside surface of the tube body, so that we call it welded steel tube. The inside weld seam can be removed or not removed, depending on customer's order. ERW welded steel tube

ERW Steel Pipe. Electric Resistance Welded Steel Pipe. Usage:Used for low pressure liquid delivery, such as water, gas, and oil. Oil drilling and machinery manufacturing, etc. Process:ERW :Electric Resistance Welded pipe. HFI:High Frequency Induction weld pipe. EFW:Electric Fusion Welded Pipe. Standard:API 5L, API 5CT, ASTM 53, EN10217, DIN 2458. IS 3589, JIS G3452, BS7 Pipe Demystified Steel Supply LPElectric Resistance Welded, often abbreviated as ERW, is a process that uses specific machinery to shape the pipe and tubing. A continuous steel sheet is unwound from a coil and shaped using contoured rollers, forcing the edges together under pressure. These edges are then welded together by heating the material to over 2,000 degrees. After welding, the pipe or tubing Seamless Steel Pipe and Tube, Seamless Carbon Steel Pipe High-pressure seamless steel tubes for chemical fertilizer equipments GB/6479-2000 ASTM standard Black and hot-dipped zinc-coated steel pipes welded and seamless ASTM A53 Seamless carbon steel for high temperature service ASTM A106 Seamless cold-drawn low-carbon steel heat exchanger and condenser tubes

Performance of structure steel pipe application. structure pipes Welded Steel Pipes for Sales from leading Welded Steel Welded steel pipe are common pipe type with technology and craft of welding. Normally welded steel pipe may divide into two categories such as electric resistance welded steel tube (ERW) and Spiral welded steel pipe. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency electric resistance welded pipe, gas welded pipe, furnace welded
LASW WELDED STEEL PIPE, LASW Welded Steel Tube, with the production method of longitudinal welded arc welding. ERW Welded Steel Pipe is produced by electric resistance welding method, from raw material of hot rolled or cold rolled steel plate, steel coils. There is a straight weld seam on both inside and outside surface of the tube body, so that we call it welded steel tube. The inside weld seam can Welded Tubes - Sachiya Steel International Steel TubesSep 17, 2019 · About Welded Tubes. our different welding processes are typically used for making a tube. Since there is no filler metal in these welds, the welds are at least as strong as the parent metals. High Frequency (HF) Welding. Today, most mild steel and the aluminum tube is welded with HF welders, which are also suitable for 400 series stainless and even 300 series if the tubing is for decorative use.
