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.
Requirement Profile …
… 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 |
Pipeline Production
… 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. |
