Submerged arc welding pipe, SAW pipes, SAW pipe manufacturer, SAW pipes Exporters, Welded pipe

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).

Success Stories

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 steel construction.

Size:

(O.D×Wall Thickness)mm×Length(mm)

219-3200mm×5-30mm x 12000mm+500mm

In addition to above specification, the pipes can be produced according to customer's requirements.
