EBK Clad

The oil & gas, chemical and mechanical engineering industries are increasingly turning to materials possessing high corrosion and wear resistance properties. Clad materials combine corrosion and wear resistance properties with high strength carbon manganese steels. To satisfy these requirements Eisenbau Krämer manufactures longitudinally welded clad pipes for applications including:

  • Gathering lines
  • Components in refineries
  • Storage tanks
  • Chemical plants
  • Offshore-pipelines


As a standard, Clad steel pipes are manufactured in the
following dimensions:

  • Length: up to 42‘ (13.200 mm)
  • Diameter: 14‘‘- 56‘‘ (355 - 1.422 mm)
  • Wall thickness of the base material:
  • 0.375‘‘ - 2.5‘‘ (9,5 - 63,5 mm)
  • Thickness of cladding: 0.06‘‘ - 0.16‘‘
  • (1,5 - 4,0 mm)



Pipes are manufactured from metallurgically roll-bonded plates. This metallurgical bond guarantees the integrity of the clad pipes throughout subsequent fabrication processes, including the production of bends and other fittings.

A full range of carbon steel grades is available, including the commonly used API 5L and ASTM A516 range, which may also be offered as compliant with sour service requirements. The CRA layer can be produced to a wide range of specifications, including:

Type 304L, 316L, 904L, Alloy 825, Alloy 625


In addition to extensive production test results, the intensive research and development programme undertaken by Eisenbau Krämer has resulted in a remarkably extensive data bank covering the corrosion properties, mechanical values and welding results, which can be made available to clients to assist in developing thoroughly engineered solutions to their project requirements.

The Electro-Slag Welding (ESW) process used by Eisenbau Krämer not only provides homogeneous welding structures with excellent mechanical and corrosion properties, but additionally guarantees low dilusion between CRA and base metal, even at high output rates.
