Spiralweld pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another.

Carbon Steel Spiral Welded Tubes are used in onshore and offshore oil and gas Tubelines that require critical service, high performance and tight tolerances. Carbon Steel Spiral Welded Tubes are also being used for low pressure liquid delivery, such as gas, water, and oil.
American Piping distributes an extensive selection of welded pipe, including Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) carbon steel pipe — along with their respective flanges and fittings. We also carry A139 — Grade B, A252 Grades 2 & 3 spiral weld pipe, and A691 chrome moly pipe.
Spiral Welded Steel Pipe, Sell Water Pipe, Youfa Gas Tube
The spiral welded steel pipe is manufactured using hot rolled steel strip which is spiraled at room temperature to be welded. Automatic submerged arc welding is the most commonly used method in the spiral tube production, and the end products come with welding seam both inside and outside.
• Pipes can be produced with diameters up to 3000mm and wall thicknesses up to 25mm. • We can provide pipes in all requested steel grades due to our worldwide network of coil producers. • Pipes can be produced with lengths up to 53m without circumferential weld. Longer tubes can be achieved by welding.
Classification of the welded pipe for construction
Jan 23, 2019 · Spiral welded pipeIt is made by rolling a low carbon carbon structural steel or a low alloy structural steel strip into a tube blank at a certain angle of a helix (called a forming angle), and then welding the pipe seam, which can be used in a narrower manner.
Reliant Pipes custom cuts and fabricates Structural Grade Carbon Steel Pipe, mid-welding pieces together for our customers. Our specialty is to have in-stock 20' lengths of various diameters and thicknesses ASTM A252 GR2, GR3, and limited use structural pipe.
Steelpipe has been at the forefront of pipe technology and innovation since it commenced trading in 1903. Today, we manufacture high quality spiral welded steel pipes to the highest international standards for domestic and overseas markets.

In a spiral saw pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe. Because of the method of manufacture, a wide variety of diameters can be produced. Spiral saw pipes are used for low-pressure services.
Spiral-welded pipes. Steel pipes with a spiral seam are mainly seen with larger diameters. The weld seam is visible in spiral form over the surface of the pipe. The welded seam is welded spirally over a twisted plate and thereby has a visible weld bead, on both the inside and the outside. The weld seam is welded under powder cover.
Spiral Weld Steel Pipe Manufacturing And Coating - Jindal
Producing the Best Quality Pipe, From the Best Steel Jindal Tubular USA, LLC is a large diameter spiral weld steel pipe manufacturing and coating facility located on the Mississippi Gulf Coast in Hancock County at the Port Bienville Industrial Park.
What is The Differences Between LSAW Pipe and SSAW Pipe
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.
Spiral welded steel pipe is used throughout the world in a wide variety of applications including water and sewerage transmission, outfalls, hydro generation and irrigation schemes. Steelpipe concrete lined steel (CLS) water pipe is used across New Zealand and the Pacific for its inherent toughness, high quality welding and testing, flexibility, versatility, safety in service, dependability and cost-effectiveness.
ASTM A252 Pipe Pile Specifications (In seamless & welded
Welded pipe pile referred as ERW (electric resistance welded), LSAW (Longitudinal Arc Sub-merged Welding) and DSAW/SSAW (Spiral Arc Welded Pipe). Chemical composition and Mechanical Properties ASTM A252 allows a limit of phosphorous maximum at 0.050%, This is because P will make steel more fragile and break, further more higher P is not good for welding processes.
In the case of high thickness pipe, multiple pass welding is done. In a spiral saw pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe. Because of the method of manufacture, a wide variety of diameters can be produced.
