Specification

SSAW steel pipe, also known as spiral submerged arc welded pipe, is a spiral welded steel pipe produced by double-sided submerged arc welding. Spiral welded pipes are formed using narrower sheets or hot rolled coils, which greatly reduces their production costs. The spiral welding process allows the production of large diameter pipes suitable for transporting large quantities of oil and gas.


Advantages:

SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to lsaw steel pipes

Due to its spiral seam ssaw pipe has an accurate diameter accuracy and strength

The sizes are adjustable & can be tailored to end-users requirement


Uses:

transporting liquids, low-pressure applications, piling pipe, under ocean water application, water lines, pipe bridge, oil & gas, drainage projects, construction piling, irrigation, boiler manufacturing, sewage treatment, thermal industry, road & highways, retaining walls, trestle, seawalls, cofferdams, harbor structure

Process

Spiral steel pipe (SSAW) is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The 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.
