Product Description

Product Description

SSAW STEEL PIPE

Introducing the SSAW steel pipe, an abbreviation for Spiral Submerged Arc Welded steel pipe. This marvel of engineering is crafted through a sophisticated spiral welding process using double-sided submerged arc welding. By utilizing narrower sheets or hot-rolled coils, we are able to significantly cut down on production costs. The spiral formation of these pipes allows them to accommodate large diameters perfectly suited for the efficient transport of vast quantities of oil and gas, making them indispensable in a range of industrial applications.

Process
In the world of advanced steel production, the Spiral Submerged Arc Welding (SSAW) Process stands out as a benchmark of excellence. Also known in industry circles as HSAW pipe, this method involves a helix-shaped welding line, sharing the same high-performance welding technology seen in LSAW pipe production. The distinctive feature here is the spiral weld, in contrast to the longitudinal weld of LSAW. The manufacturing journey begins with rolling the steel strip at a strategic angle relative to the pipe center direction, leading to a seamless formation and welding process that results in a robust spiral seam.

Application
SSAW steel pipes find a multitude of applications across diverse sectors. They are essential for Oil and Gas Pipeline systems, ensuring secure Water Transmission and Liquid Transportation. In the realm of construction, they serve as a cornerstone for Building Construction, Steel Structure Construction, both Offshore and Onshore Construction projects, Piling Works, and more. Their versatility extends to supporting Electricity and Heating Power systems, making them an all-encompassing solution for modern infrastructure needs.

ADVANTAGES OF SSAW STEEL PIPE

(1) Our utilization of steel strips with consistent width allows for the creation of steel pipes in varying diameters, and particularly facilitates the production of large-diameter pipes using narrow strip steel, optimizing material efficiency.

ADVANTAGES OF SSAW STEEL PIPE

(2) Under identical pressure conditions, the spiral welds endure less stress compared to straight seams, handling only 75% to 90% of the stress endured by straight seam welded pipes. This unique feature permits our pipes to withstand greater pressures, and offers a reduction in wall thickness by 10% to 25% without compromising on strength.

ADVANTAGES OF SSAW STEEL PIPE

(3) These pipes boast remarkable precision with diameter tolerance not exceeding 0.12%, minimal deflection under 1/2000, and ellipticity less than 1%. This ensures the sizing and straightening processes are largely unnecessary, streamlining production.

(4) The production of these pipes is a seamless and continuous process. Theoretically, it facilitates the creation of infinitely long steel pipes with minimal wastage from cutting, thereby boosting metal utilization rates by 6% to 8%.

ADVANTAGES OF SSAW STEEL PIPE

(5) The production process for our spiral welded pipes offers unparalleled flexibility and ease in type replacement adjustments, enhancing operational efficiency.

(6) With lightweight equipment and minimal initial investment, our operations can be mobilized with trailer-type flow units, enabling the production of welded pipes directly at construction sites, promoting on-site efficiency.

(7) The process is highly conducive to mechanization and automation, paving the way for streamlined, efficient production.
