Longitudinally welded steel pipes / Carbon Steel SAW Pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. All products are industry-standard conforming to or exceeding API, ASTM, ASME,
Advantages of Spiral Welded Pipe SSAW - Zhangzhou Steel The spiral welded pipe is made up of hot-rolled coiled steel using a double-sided submerged arc welding method. The welding process allows the steel pipes manufacturers to produce large-diameter steel pipes suitable for different applications. Our manufacturing facilitys main focus is to produce SSAW steel pipes.

Spiral Welded Pipe - an overview ScienceDirect Topics22.214.171.124.5 Spiral-welded pipe. Spiral-welded pipe is produced from coils of steel that are unwound and flattened. The flattened strip is formed by angled rollers into a cylinder of the desired diameter. Interior and exterior SAW seal the spiral seam. At the end of the coil, a new coil is butt-welded to the trailing edge of the pipe, forming a
Submerged Arc Welding Flux and Wire Lincoln ElectricFlux for Seam Welding of Pipe (5) High Performance / Alloy Flux (1) Lincoln Elecric has a variety of submerged arc welding flux and wire designed to be paired together to meet any industry specific welding requirement.
Submerged Arc Flux and wire combinations for single- and multiple-pass welding in automatic and semi-automatic applications. Metal-Cored Wires Solid and flux-cored wire for high deposition rates with the ability to weld over mild surface contamination.
Submerged arc welding (SAW) - ylfluxSubmerged arc welding system can become quite complex by incorporating additional devices such as seam followers, weavers, and work rovers. SAW Welding Diagram . Figure 10-59. Block diagram of SAW (submerged arc welding) Equipment. Advantages. The major advantages of the SAW or submerged arc welding process are:high quality metal weld.
Weld Defect - an overview ScienceDirect TopicsThe high performance and good penetration of submerged arc welding means that it is best to weld even somewhat thicker materials with as few passes as possible. However, this results in high yield energy, so it may be better to make several passes when welding difficult materials.
The lsaw steel pipe of the 54.HAN GUAN welded pipe platform are 508~1372mm in diameter. The weld seam adopts X-shaped groove, the inner weld is three-wire submerged arc welding, and the outer welding is multi-layer multi-channel three-wire submerged arc welding. Ultrasonic testing of the weld was carried out after 24h or 48h of welding.Carbon Steel Welded Pipe Supplier - TopperCarbon Steel Welded Pipe Carbon steel welded pipe belongs to the family of the carbon steel pipe. It is usually divided into three welding types:electric resistance weld (ERW), longitudinal submerged arc weld (LSAW), spiral submerged arc weld (SSAW). These pipes have high performance and widely used in high-pressure applications.
