Spiral welded pipe hydrostatic test is to test whether the steel pipe meets the design requirements at the specified pressure by filling, pressurizing, and maintaining pressure into the test steel pipe. It is the most intuitive and closest testing method to the actual use of the steel pipe.
SPECIFICATIONS FOR SPIRAL PIPE AND FITTINGSSMC spiral fittings are manufactured with an elbow lock seam, lap seam (i.e. stitch weld, riveted, tack weld or solid weld), standing seam or butt weld seam. These may be with or without duct sealant. All fittings can be manufactured with: Complete Seal Spiral Pipe System 6 to 24 Diameter (even sizes)

SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap
Spiral Welded Pipe - an overview ScienceDirect Topics220.127.116.11.5 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
Spiral Welded Pipe Manufacturing Process - Permanent SteelSpiral welded pipe unit The spiral welded pipe unit is used to produce large-diameter steel pipes with a diameter of (892450)mm×(0.525.4)mm and a length of 635m. The production method is continuous and discontinuous. The unit adopts spiral forming, and the welding adopts two steps of pre-welding and final welding.
Pipe Process:The raw material used in manufacture of Spiral SAW is H.R. Coil. It is continuously formed to require the specific diameter of the pipe, spirally welded at high speed and cut to required length. The following operations are carried out when the material is loaded for making of the pipe.
Spiral Welded Steel Pipe Jindal MS Spiral Pipes supplierJindal MS Spiral Welded Pipes supplier. A Spiral welded pipe is also known as a helical welded pipe. Industries such as tap water engineering, chemical industry, electric power industry, petrochemical industry, agricultural irrigation as well as urban construction use a large diameter spiral welded steel pipe in their applications. The manufacturing process of this product involves cold
Spiral Welded Steel Pipe Philippines SSAW/HSAW Pipe Spiral welded steel pipe is a low carbon carbon structural steel or a low alloy structural steel strip rolled into a tube blank with a certain helix angle (also called forming angle), and then welded and made into a pipe joint, which can use a narrow strip steel production of large diameter steel pipes.. Spiral welded pipes are single-sided welded and double-sided welded.

Stainless Steel Spiral Pipe Price Supplier Shanghai Metal Corporation is a leading stainless steel spiral pipe manufacturer and supplier. The stainless steel spiral pipe is made by winding a low carbon structural steel or a low alloy structural steel strip into a tube blank at a certain spiral angle, and then welding the tube seam, which can produce a large diameter Steel pipe with a narrow strip steel.
The difference between seamless pipe and seamed pipeDec 31, 2020 · The welded steel pipe is formed by welding a steel plate rolled into a tubular shape by a seam or a spiral seam. In terms of the manufacturing method, it is further divided into a welded steel pipe for low-pressure fluid transportation, a spiral-welded electric steel pipe , a direct-wound welded steel pipe, an electric welded pipe, and the like.
Welded steel pipe, such as water pipes, generally through the flat plate by welding after bending up, you can find a seam in the above; is generally thicker in diameter spiral weld. In performance, especially on the bearing capacity has greatly improved as compared with ordinary steel
