Product Details

Description

SSAW steel pipe, also known as spiral submerged arc welded steel 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.

Sizes:

Out diameter:219mm-3620mm

Wall thickness: 5mm-25.4mm

Length: 3m-12m

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.
