Production Method:

UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press.

Longitudinal edges of the plates are then tack welded followed by internal and external welds.

Pipes manufactured by this process are subjected to expanding operation in order to relieve internal stresses and obtain a perfect dimensional tolerance.

After the pipes are conveyed to cold expansion, hydrostatic testing and NDT inspection, the pipes will be subject to final inspection for the compliance to customer requirements.

Starting from incoming control up to the final inspection stage; entire process is monitored and supported by computerized system. Traceability is achieved by input controls and barcodes through entire production lines.

Packaging of Longitudinal Welded Pipe:

Wuxi Gotele Metalare packed and labeled according to the regulations and customer's requests.

Great care is taken to avoid any damage which might be caused during storage or transportation.

In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

Application:

Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. LSAW pipe are also used in conveyance of flammable & nonflammable liquids, and as structural members in construction projects.
