API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

For oil and gas storage, the best recommended type is ERW longitudinal, owing to its quality, ease of transport and cost. Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. API 5L Welded Line Pipe Supplied by AGICO3. Spiral Welded Pipe. Spiral welded is produced by winding and welding steel plate or thick HR coil in a circular fashion. This method allows for increased sizes and lengths. Diameters range between 24 200, while maximum wall thickness is about 20-25mm. The welding technique is referred to as Helical SAW (HSAW).

Differences between LSAW Steel Pipe and Spiral Welded Pipe

Apr 20, 2017 · LSAW steel pipe is made by using strip steel as raw materials and doing longitudinal welded in the high-frequency welding equipment(hence the name due to the weld forms a straight line). In accordance with the use of different, there are different following production process (can be divided into scaffolding tube, fluid tube, wire casing, bracket tube, fence tube, ERW Steel Pipes:ERW steel pipesERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. ERW pipes means Electric Resistance Welded Pipes. A plate rolled to become a pipe and welded using Electric Resistance Welding process. Usully for for high diameter. (cheapest process avaiable)

Erw pipe and electric Welded profiles:buy from Metinvest

Welded spiral pipe manufacturing. Steel coils are used to make spiral pipes. Manufacturing pipes up to 2,520 mm in diameter using feedstock of a similar width by resetting a line is a key advantage of this technology. A spiral welding process results in pipes with a diameter-to-wall thickness ratio of 100 or higher. Helical welded pipes - Sunny SteelHelical welded pipes. Helical welded pipes is the low-carbon structural steel or low alloy steel strip by the helix angle (called molding angle) rolled into a tube, and then the tube made of seam welded together, it can be used a narrow bandsteel production of large-diameter steel pipe.

    the production process of welded steel pipe, welded steel pipe

    The production process of welded steel pipe. Sunny Steel produce an extensive selection of welded steel pipe including ERW, HFI, EFW, LSAW, DSAW and UOE type carbon steel pipe along with their respective flanges and fittings.. Welded steel pipe manufacturing process is simple, efficient, and more varieties of different specifications, equipment, less capital, but the Difference Between Helical Welded Pipes And Longitudinal The compound stress can be derived from the formula =Y(l/4sin2+cos2)1/2 , refers to the helical angle. Normally, the angle for helical welded pipe is 50° to 70° while for longitudinal pipe is of course 90°, so it can be concluded that the compound stress sustained by helical welded pipes is 60 to 85% of the latter.
