API 5L welded steel pipes are basically tubular products made with a weld, either from plates, sheets, coils, strips or bands. API 5L welded steel pipes supplied by Metallica are suitable for welding, bending, flanging, and similar forming operations. We sell all our API 5L welded steel pipe products with Original Mill Test Reports, which include details on mechanical testing such as tensile, bending, flattening,
Basic Understanding of Weld Corrosion2/Corrosion of Weldments Fig. 1 Schematic showing the regions of a heterogeneous weld.

Factors That Lead to Corrosion in WeldsThe Metallurgical FactorsTypes and Causes of Corrosion on WeldsGalvanic CouplesWeld Decay of Stainless SteelPreferential Weld CorrosionWelding Practices to Minimize CorrosionImage:Fabricating & Metalworking The metallurgical, physical and chemical changes caused by the welding process affect the corrosion resistance of the weld. This leads to both the heat affected zone (HAZ) and the weld metal corroding faster or slower than the base metal. Cases of uniform corrosionacross the base metal and weld metal, or the base metal corroding and the weld metal remaining unaffected, are also possible.BS S235JR SSAW Spiral Steel Pipe from China Sino EastSino East Steel supply BS S235JR SSAW Spiral Steel Pipe with competitive price list, steel tubes for sale are in wide sizes such as from 1/8" to 30" (outer diameter), and wall thickness is about Sch10 to Sch140.

China Spiral Welded Pipe Manufacturers and Suppliers SSAW pipe can be widely used in the mechanical treatment field, petrochemical industry, transport and construction field; ordinary structural purposes and mechanic structural purposes; also can be used in low and medium pressure boiler for the transportation of fluids; the transportation of fluids in the projects and big equipment, such as the transportation of oil, water, gas and etc.
Construction Welded Steel PipeStraight seam anti-corrosive steel pipe generally refers to the use of special technology for ordinary steel pipe anti-corrosion treatment, so that Construction Welded Steel Pipe has a certain anti-corrosion capacity, generally used for waterproof, anti-rust, anti-acid and alkali, anti
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
Longitudinal-seam Submerged Arc Welded (LSAW) pipes 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
SSAW Steel Pipe - Threeway SteelThreeway steel has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We have 10 traditional one-step production lines and 1 two-step production line that enabels to produce finely pre-welded SAWH steel pipe of 360000 tons per year,and we have become the leading enterprise in this industry in virtue of large productivity and advanced technical equipment.
The DC-1500 is designed for SSAW steel pipes (submerged arc welded pipes). This application is outstanding for quickly welding together the metal sheets and creates a secure bonding between welds. This application produces high productivity, fast travel speed, high repeatability, and quality results.SSAW Steel Pipes Welded Pipes anti-corrosion Products SSAW Steel Pipes Welded Pipes anti-corrosion.
