Electric-resistance welded (ERW) tube and pipe is made by longitudinally welding HR coil. ERW material is typically limited to a maximum of 24 in diameter, due to the typical width of HR coil (maximum of 76 or 2.25m) with an average pipe length of 18m to 24m and a maximum wall thickness of 25mm. China Longitudinal Welded Steel Pipe, Longitudinal Welded Buying or selling minerals has never been easier! If you are about to import Longitudinal Welded Steel Pipe, you can compare the Longitudinal Welded Steel Pipe and manufacturers with reasonable price listed above. More related options such as steel tube, steel pipe, tube could be your choices too.
All Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes. There are many Differences between Seamless & ERW Pipe. The main Difference is that the Seamless Piping is suppliers by hot-working steel or, if necessary, by subsequently cold-finishing the hot-worked product Difference between helical welded pipes and longitudinal Therefore, compared to longitudinal welded pipes, the helical pipe, with lower sustained stress, can guarantee more safety and longer service of life. In terms of various diameters of pipes. As for longitudinal welding, the width of the steel plate should be strictly stuck to the diameter of the pipe. ERW Pipe Weld Inspection - InnerspecThe temate BW-LT(ERW) is an automated system for inspection of longitudinal welds in ERW tubes. The couplant-free EMAT technique permits inspection immediately after welding and reliable detection of all API defects and poor ID scarfing. The lack of coupling fluid permits inspection of tubes at higher temperatures, and installation immediately

Besides LSAW pipes we can also supply carbon steel ERW pipes, spiral welded pipes, seamless steel pipes & fittings, stainless steel tubes etc. for your diversified requirements by one-stop servie. 1, Sizes:323mm - 1820mm 2, Wall thickness:8mm - 120mm LSAW pipe, DSAW pipe, longitudinal welded pipe - steel LSAW pipe, DSAW pipe, longitudinal welded pipe, LSAW (longitudinal Submerged Arc Welding) pipe is fromed by JCOE with one straight welded seam, the outer diameters usually from 323mm to 1420mm. When the outer diameter is 914.4mm above, it's allowed two straight welded seams. Longitudinal Submerged Arc Welding (LSAW) Processes When operational conditions require high wall thickness due to high internal or external pressures, LSAW (Longitudinal Submerged Arc Welding) pipes are commonly the most economical solution. The LSAW pipe diameter range is larger than ERW (Electric resistance welding), normally from 16 inch (406 mm) to 60 inch (1500 mm).
Longitudinal welded stainless steel pipes are made by bending and welding wide steel plates and most commonly used in oil and gas industry applications.

The first is longitudinal welding, which welds the long seam of the pipe on both the inside and the outside. The final welding step is circumferential welding. Using the submerged arc welded (SAW) process, we fit the cans together to create the specific length you request for your pipe.

Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp. astm a106 53 erw welded steel pipe for structureIt is available in Type S (seamless), Type E (ERW, electric resistance welded longitudinal seam), and Type F (furnace welded).
