Berg Pipe SAWH Manufacturing Process

Pipe is welded on one of three welding stands using a three-wire inside pass followed by a two-wire outside pass. The deposits overlap to provide a full penetration weld. The welding process is computer controlled and weld alignment is automatically adjusted by a laser tracking system. Home - TubaceroWelding processes:ERW, SAWH y SAWL. Manufacture of carbon steel pipes by High Frequency Electric Resistance Welding (ERW), Longitudinal Submerged Arc Welding (SAWL) and Helical (SAWH) in diameters from 6 to 144 inches, in wall thicknesses up to 2.5 inches

SAWH pipes

SAWH pipes refers to the use of submerged arc welding process, made of welded steel pipes with spiral seam.. Generally used:welded pipes conveying fluid, metal structures, pile and so on. Our products are widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of 20 key product of development. SSAW Steel Pipe, SAWH Steel Pipes Supplier In ChinaThe welding process allows the steel pipes manufacturers to produce large-diameter steel pipes suitable for different applications. What Are The Advantages of SSAW Pipes. SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes. Due to its spiral seam SSAW pipe has an accurate diameter accuracy and strength SSAW/SAWH Steel Pipe Supplier China CUMIC SteelOverview 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.

STANDARD SPECIFICATION FOR SUBMERGED ARC

WELDED (SAWH) LINEPIPE (ONSHORE) Page 4 of 35 1 SCOPE This specification establishes the minimum requirements for the manufacture of submerged arc helical welded steel line pipe in accordance with the requirements of API (American Petroleum Institute) Specification 5L, FortyFifth Edition, 2012 and makes restrictive Spiral seam double-sided submerged arc welded steel pipe The company has nine sets of SAWH spiral seam double-sided submerged arc welded steel pipe units, which can produce 400,000 tons of spiral seam double-sided submerged arc welded steel pipes per year. The products can be used in shale gas, oil, natural gas, ore slurry transportation, tap water, sewage engineering, heating network transformation The Helical Weld Angle of SAWH Steel PipeSAWH steel pipe weld near the defect with parallel (Longitudinal crew) due to the spiral weld force is smaller, so the risk of expansion not as good as straight weld large. The radial stress is the maximum stress in the pipe, the weld is in the direction of the vertical stress under maximum load.

The progress in SAWH steel pipes welding technology

Nov 06, 2016 · Submerged-arc helical welded pipe (SAWH pipe), a type of spirally welded steel pipe produced by using the submerged arc welding method. With the continuing improvement in quality of hot rolled coils and the progress in pipe-processing equipment and technology, the quality of spirally welded pipes was enhanced rapidly. helical weld line steel pipeLine Steel Pipe.
