Application: As conveyer pipe in the fields of petroleum, heat and natural gas, construction pipe, ground piling pipe Carbon Steel Spiral Welded Steel Pipe Submerged Arc Welding - Image ResultsSubmerged arc welding pipe, SAW pipes. SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available. Submerged arc welding (SAW) is a common arc welding process. The process is normally limited to the flat or horizontal-fillet welding positions (although horizontal groove position welds have been done with a special arrangement to support the flux).

The double submerged arc weld (DSAW) process is similar to that of the ERW process in that coils of carbon steel are unrolled in a continuous ribbon. As the DSAW method of manufacturing is typically used for larger diameter pipe, the method of roll forming the skelp is similar to but not exactly like that of ERW.

Double Submerged Arc Welded (DSAW) Steel Pipe - Guangdong carbon steel spiral welded steel pipe Submerged arc welding
Double Submerged Arc Welded (DSAW) Steel Pipe Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air. Both inside and outside welds are performed. Longitudinal Submerged Arc Welding (LSAW) Processes :: Total carbon steel spiral welded steel pipe Submerged arc weldingIn LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter. Pipe Manufacturing Process / Methods for Seamless & Welded PipeSAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency carbon steel spiral welded steel pipe Submerged arc welding
Quality inspection of double-sided submerged arc welding carbon steel spiral welded steel pipe Submerged arc welding
The double-sided submerged arc welded spiral steel pipe should be subjected to mechanical performance test, flattening test and flaring test before leaving the factory, and must meet the standard requirements. The quality inspection method of double-sided submerged arc welded spiral steel pipe is as follows: 1. SSAW Steel Pipe, SAWL Steel Pipe - Seamless Steel PipeSSAW steel pipe (spiral submerged arc welded steel pipe) is formed by spiral bending of hot-rolled strip steel, and spiral seam steel pipe (also called spiral welded pipe, spiral pipe spiral steel pipe) is formed by automatic welding of submerged arc for inner and outer joints. SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel PipeThe spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roller is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding joint flush. Machine of manufacturing SSAW steel pipe. Edge planing machine, edge milling machine, pipe cutting machine,butt welding machine, pinching machine, hydraulic testing machine.

Spiral Weld Pipe Specifications and Grade Chart - API 5L carbon steel spiral welded steel pipe Submerged arc welding
API 5L Carbon Steel Spiral Welded Tubes & Tube s is widely used in different applications which include line Tubes for oil, gas, chemical and petrochemical industries, Tubes for oil and water wells and Tube for agriculture, structural, pilling and construction requirements. Carbon Steel Spiral Welded Tubes are used in onshore and offshore oil and gas Tubelines that require critical service, high performance and tight tolerances. Spiral Welded Pipe Manufacturing Process - Carbon Steel Pipe carbon steel spiral welded steel pipe Submerged arc weldingSpiral welded pipe (SSAW/SAWH): a low carbon carbon structural steel or low alloy structural steel strip is rolled into a tube blank at a certain spiral angle (forming angle), and then the tube seam is welded together. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness, and the welded pipe shall be ensured that the hydraulic test, the tensile strength of the weld and the cold bending performance carbon steel spiral welded steel pipe Submerged arc welding Spiral Welded Steel Pipe Philippines | SSAW/HSAW Pipe Prices carbon steel spiral welded steel pipe Submerged arc weldingSSAW Pipe (Spiral Submerged Arc-Welding Pipe) also called HSAW pipe, welding line shaped like a helix. It is using the same welding technology of Submerged Arc-Welding with LSAW Pipes. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.
