The Next Generation

BERG-LAY® – THE NEXT GENERATION

The ever-increasing demand for corrosion-resistant steel pipes has created the need for new approaches in their manufacture. Solid CRA (Corrosion Resistant Alloys) and metallurgically bonded CRA/CS (Carbon Steel) composite solutions – commonly known as „Clad Pipes“ – were standards set in the past. In more recent years „CRA-lined pipes“ have entered the market substituting metallurgically clad pipes by a mechanically lined solution with substantial cost advantages.

First generation of classical mechanical-lining was sucessfully effected by expanding a CRA-pipe into a CS-pipe, a so called „Expanded Lined Pipe“. Our solution of a „Rolled Lined Pipe“ now takes the concept of mechanical lining to a new level: BERG-LAY® – The next generation of CRA-lined pipe.

BERG-LAY® – STRONG IN

ADAPTABILITY TO SPECIFICATION

  • Corrosion case more specifically adressable by enhanced number of combinations of CRA and CS materials
  • Pipe diameters available from 6“ to 100“
    (168 mm to 2.540 mm), pipe lengths random up to 40 feet
  • Large and small quantities

COST BENEFITS

  • Substantial material cost savings over solid and clad solutions
  • Wider liner choice to fit the corrosion purpose opens the door to applying sophisticated liner grades at non-exaggerated costs.
  • Short delivery time due to good availability of pre-material (~ 3-4 months for plates resulting in ~ 5-6 months for pipes)

PROCESSABILITY ON-SITE

  • Strong liner buckling resistance for common on- and off- shore installation activities (S-Lay, J-Lay, Reel-Lay, cold bending, ...) obtained from:
    - high levels of mechanical grip between backing steel and CRA liner
    - full length weld fixation of CRA liner in
    CS carrier (for further increase of liner buckling resistance the full length CRA weld fixation in CS carrier can be duplicated,
    triplicated ...)
  • Pipe cutting and immediate rebevelling/
    rewelding at any position along pipe length possible because of very tight fit between material layers
variable material combinations
