API 5L steel line pipe is for oil and gas industries pipelines, developed for different working environments. Comparison Of ERW Steel Pipe And LSAW Steel Pipe Aug 22, 2018 · Comparison Of ERW Steel Pipe And LSAW Steel Pipe Posted Aug 22, 2018 in China, the coil steel (sheet) produced was limited in width and unstable in quality. In addition to the use of seamless steel pipes with high cost and high quality, the steel pipes with small diameters of -20-89mm are mainly straight seam pipes, and the quality grade is
Seamless steel pipes are mainly used in oil pipeline and gas pipeline, but seldom used in oil pipelines with long-distance. Most long distance pipeline applied ERW pipes, SSAW pipes and LSAW pipes. Here are comparisons of technological features and performance of these pipes. Differences Between ERW and LSAW Steel PipeSep 23, 2020 · ERW steel pipe welding does not need to add welding wire; LSAW steel pipe requires welding wire. 3. The difference in appearance Both the inner and outer welds of the ERW steel pipe need to be removed, so it is beneficial to anti-corrosion; the extra height of the weld on the inner and outer walls of the LSAW steel pipe is not good for LSAW steel pipe, Seamless steel pipe, Stock pipe, Pipe As agent of TPCO group, Baosteel group, Yanbao group,Fengbao,Ye steel,Pan steel,Heng yang ,Julong,we have ten thousand tons stock year round of Seamless steel pipes and Lsaw steel pipes in different sizes. Seamless pipe diameter from 21mm to 920mm,Lsaw steel pipe diameter from 406.4mm to 1524mm,Large size can be negotiated, and some stocks for pipe fittings.

Geometry accuracy of LSAW pipes is better than SSAW pipes, a key in the ease of installation. The welding line of LSAW pipe is around 60% lesser than of SSAW pipes. Using steel plates, quality of LSAW pipe can be tested by non-destructive procedures. While SSAW pipes using hot-rolled coils should be tested with destructive methods such as x-ray. Seamless Steel Pipe Wall Thickness ToleranceSeamless steel tubes are mainly used as petroleum geological drilling tubes, cracking tubes for petrochemical industry, boiler tubes, bearing tubes, and high-precision structural steel tubes for automobiles, tractors, and aviation. In the plate, Q345B seamless steel pipe belongs to low alloy series.

What are differences between SAW pipes and ERW pipes Haihao Group could provide many kinds of pipes made by carbon steel,stainless steel and alloy steel like weld steel pipe and seamless steel pipe.And at first in welded steel pipe,you will find different methods of forming process, such as ERW,LSAW,SSAW.So lets talk about the differences between SAW pipes and ERW pipe.
The SSAW pipe diameter range is from 20 inch to 100 inch, 406 mm to 2540 mm.The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress. ssaw_erw_lsaw-Cangzhou Spiral Steel Pipe (Group) Co., Ltd.Cangzhou Steel Pipe Group (CSPG) Co., Ltd. is a large-sized, key metallurgic enterprise of Hebei Province in North China, whose history dates back to 1994.
