Helically submerged arc-welded pipes (SAWH)

Pipes are manufactured according to the requirements of the following standards:


Pipes are manufactured in diameter range from 323,9 mm to 1219 mm, in length from 4 m to 24 m (line pipes) and from 4 m to 30 m (pipes for construction purposes) , with plain or bevelled ends. Pipes are supplied after hydrostatic tests and depending on requests: automatic non-destructive ultrasonic tests and/or X-ray test (pipelines).

Depending on the required mechanical and technological properties or application, the pipes are produced from the following steel grades:


Upon the customer's needs pipes are supplied as: bare - without protection coating, or with external three-layer polyethylene (PE) or polypropylene (PP) anticorrosion coatings and with internal either cement or epoxy lining. Against agreement pipes may be supplied with other anticorrosion protection e.g. galvanized pipes.

 

 

Helically submerged arc-welded pipes (SAWH) manufactured by "FERRUM" S.A. can be successfully used to produce steel fittings including tees, reducers, elbows and bends. Fittings are made by either cold or hot bending process depending on the strength parameters of steel grade as well as the diameter and wall thickness. Our offer also includes section fittings.
