ERW carbon steel pipe vs spiral pipe - Rainbow SteelSep 07, 2019 · First, differences in production processes ERW straight seam resistance welded steel pipe is rolled continuously by hot rolled coil. By using skin effect and proximity effect of high frequency current, the edge of coil is hot melted, and the extrusion roll force is pressed and welded under pressure.

Front Swing Spiral Welded Pipe Mill - HNGK ERW

When the uncoiling, coil detaching, leveling, steel cutting and welding are working, the host machine needs to stop and wait. After the steel welding finishing, the host machine starts to work again. The front-swing spiral welded pipe mill adopts intermittent production method with advantages such as low investment, and simple convenient. LSAW Pipe Manufacturing Process JCOE Winsteel GroupNov 22, 2018 · Double seam saw pipe is having a two weld seam opposite to each other. Both the welding seams welded from the internal and external of the steel pipe. In the case of heavy thickness steel pipe, multiple pass welding done. 5. Pre-welding. Joint the seam of shaped straight welded pipe. And use gas shielded welding (MAG) for continuous welding. 6.

Longitudinal-seam Submerged Arc Welded (LSAW) pipes

Longitudinal-seam Submerged Arc Welded (LSAW) pipes were made of steel plates cut from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter J, C, O or U shape, then expansion) forming processes. Furthermore, the mechanical properties of the pipe base metal and weld metal were tested, and the results SSAW Pipe Mill - HNGK ERWMay 07, 2020 · The steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine.

SSAW Spiral Welded Steel Pipe API 5L X52 PSL1/PSL2

Mechanical Tests for SSAW Spiral Welded Steel Pipe API 5L X52 PSL1/PSL2:Tensile testing of the pipe bodyThe tensile test should be carried out in accordance with ISO6892 or ASTM A370.Longitudinal samples should be used.Twice per test unit of pipe with the same cold-expansion ratio a.b.d. SSAW Steel Pipe vs. LSAW Steel Pipe - ESC GroupThe difference is SSAW pipes are welded in the helix or spiral position while LSAW pipes are welded in the longitudinal direction. Manufacturing process of SSAW pipe is by rolling and welding a steel strip in a way that the pivotal direction is oblique to the axis or pipe center, making the weld seam in a spiral line.

SSAW Steel Pipe, SAWL Steel Pipe

SSAW Pipe (HSAW Pipe) Manufacturing Process Spiral welded pipe production by submerged arc method is based on using tandem welding technique for joining inside and outside coil edges, which have been trimmed and beveled by carbide milling for high quality weld structure. SSAW and LSAW Steel Pipe - Articles FactoryJul 21, 2014 · Spiral welded pipe is mainly used for oil and gas pipelines. There are one-sided spiral pipe welding and double-sided welding, pipe should ensure that hydrostatic test, weld tensile strength and performance of cold-formed to meet the requirements. LSAW steel pipe is produced, and spiral welded pipe is hot-rolled coil production.

SSAW/SAWH Steel Pipe Supplier China CUMIC Steel

Overview of SSAW/SAWH Pipes. SSAW (Spiral Submerged-Arc Welded) steel pipes are made of narrower hot rolled plates/coils, which lowers their costs. The diameter of the spiral welded steel pipe can be very large, suitable for transporting large amounts of oil and natural gas. Spiral welded steel pipe Manufacturers & Suppliers, China spiral welded steel pipe manufacturer/supplier, China spiral welded steel pipe manufacturer & factory list, find qualified Chinese spiral welded steel pipe manufacturers, suppliers, factories, exporters & wholesalers quickly on Made-in-China.

The difference between ERW, SSAW and LSAW

Jan 29, 2017 · Spiral submerged arc (SSAW) is the direction of rolling and forming tube center line forming angle (adjustable), side molding and welding, the welding seam of the spiral line, has the advantages of steel pipe of the same specifications can produce a variety of diameter specifications, raw materials to a large range, the weld can avoid stress, stress well, the disadvantage is poor compared to geometric size, the length of the weld seam length, cracks, porosity, slag, weld Weld steel pipes, Welded steel pipe, Weld pipe, Welding Weld steel pipes Sunny Steel produce an extensive selection of welded steel pipe including Electronic Resistance Welded (ERW), Electronic Fusion Welded (EFW), and Double Submerged Arc Welded (DSAW) carbon steel pipe along with their respective flanges and fittings. Difference between ERW, SSAW, LSAW; Supplying ERW steel pipe & Tube

What is LSAW and SSAW Pipe?

Apr 09, 2021 · LSAW and SSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded ERW, SSAW, LSAW Welded Steel PipeApr 15, 2020 · ERW 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
