Oil And Gas
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.
