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.

The size of the steel pipe from 24 to 42 in the inquiry,the pipe welding methods given by the client include submerged arc welding length (SAWL), submerged arc welding helix (SAWH), High Frequency Welding (HFW). Then compare the difference between these three welding methods below:
Difference between erw and saw steel pipe, Sunny Steel ERW steel pipe weld defects only wire-line and straight welds, the inspection process easy to follow, and the defects in the maximum reflection at, once the lack of implicit, ultrasonic reflecting the strong, easy to detect. (3) ERW steel pipe related to saw steel pipe in residual stress ratio is low. Since ERW pipe deformation in the
Notes in The Process of SAWH Steel Pipe WeldingAs a result, small diameter welded pipe mostly adopt straight seam welding, while large diameter welded pipes mostly adopt spiral welding. Notes in the process of sawh steel pipe welding From the aspect of economic benefit, pipe fittings of spiral steel pipes should not only meet the requirements of engineering design, but also reduce the cost as much as possible.
SAWH Steel Pipe,as the name implies,is a steel pipe that has a seam running its entire length in a spiral form. In the past,due to the method of manufacture,SAWH Weld Pipe was relegated to low pressure and structural applications.With the development of the Submerged Arc Welding process,the production of large hot rolled coils of sufficient width and the development of dependable non
SAWH Steel Pipe-ASTM A252 Spiral Steel Pipe_ASTM A106 Structure Pipe Home>>SAWH Steel Pipe. SAWH Steel Pipe. Specification. SSAW Steel Pipe. Process:Spiral Submerged- Arc Welded Steel Pipe. Usage:Used for low pressure liquid delivery, such as water, gas, and oil; construction and piling.
SAWH pipes - Hunan great steel pipe ,ltdSAWH 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/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. Features of SSAW/SAWH Pipes
Spiral Welded Pipe Manufacturing Process - Permanent SteelSpiral 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 eed by outer diameter * wall thickness, and the welded pipe shall be
