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. It has the advantages of a longer length available; accurate diameter accuracy and strength; the sizes are adjustable & can be tailored to end-user requirements.

Note:
Oiled marking: Steel after passing were oiled to prevent corrosion, and according to user requirements for making.
Leveling milling: The flat steel anvil machine so that the original curl, and then through the edge milling machine for two-sided steel milling, so as to meet the requirements of the plate width, plate edge parallelism and groove shape.
Shear molding: The steel plate production line along the outer edge of the spiral curl into a tube.
Butt cut: Double-sided submerged arc welding using advanced technology to pre-welding, internal welding, outside welding. The welded steel pipe using a plasma-foot cut to specification length.

For low pressure fluid service; pipe piles; for cold formed welded structural hollow sections of non-alloy and fine grain steels; for pipeline transportation system of petroleum and natural gas industries(Class A steel pipe);for use as casing or tubing for wells of petroleum and natural gas industries.
