Oil And Gas

Oil And Gas Pipelines

High steel grades and extremely heavy wall thicknesses make high operating pressures possible whilst providing maximal security for the operator.

… for oil and gas pipelines:

Use of high quality steel types such as X 70 (L485MB) or X 80 (L555MB)
Pipes in the higher range of wall thicknesses and diameters (e.g., thickness 22,7 mm, X 70, and diameter 1219.2 mm)
Must endure highest pressures
In case of damage, the material only bursts in small sections (from one seam to the next)
High quality anti-corrosion on the inside and outside
The producer guarantees the constant quality of the pipes throughout the whole project
The supplier provides JIT logistics right up to the construction site
High assembling performance through continuous coordination between manufacturing party and placing party
Long lifetime of the pipes

… needs know-how and a focus on details.

Use of high-strength steel grades
Heavy wall thicknesses (of up to 25,4 mm) and lengths; large diameters (508 – 1829 mm)
Helical decoiling using a decoiling equipment and subsequent forming via a straightening equipment
Joining (on the interior and exterier) using the submerged-arc welding process (SAW)
Pipe lengths of up to 18 m are possible
The pipes are “round by nature” throughout their whole length (without re-calibration)
Comprehensive tests are run throughout the whole production
Each single processing step is meticulously documented.
Closest tolerances are achieved concerning straightness, ovality and exactness of the diameter.
