Submerged arc welding (SAW) is a common arc welding process. SAW is
normally operated in the automatic or mechanized mode, however,
semi-automatic (hand-held) SAW guns with pressurized or gravity
flux feed delivery are available.

The process is normally limited to the flat or horizontal-fillet
welding positions (although horizontal groove position welds have
been done with a special arrangement to support the flux).

SAW pipe is made of hot rolled coiled steel by automatic submerged
arc weld under normal atmospheric temperature. All the pipes are
produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM
A252-89 standard. These pipes mainly used in petroleum and natural
gas industry to transport flammable and non-flammable liquid and
219-3200mm×5-30mm x 12000mm+500mm
In addition to above specification, the pipes can be produced
according to customer’s requirements.

Spiral welded steel pipes are widely used in Oil, Natural Gas,
Water and other flammable & nonflammable liquid conveyance and
distribution pipelines, steel structures for construction and other
general purposes by means of their wide size range.
