Eisenbau Krämer mbH (EBK), has been producing longitudinally welded steel pipes since its establishment in 1921. During the last ten years, EBK has become a manufacturer of not only standard steel pipes, but also a supplier of special pipes to be used in critical applications.
Continuing the company's ambition to be a quality supplier, EBK was the first German manufacturer to obtain ISO 9001 certification for the production of longitudinally welded steel pipes.
Line pipe and process pipe applications include transmission lines, flow lines, jetty lines, steam lines, slug catchers, compressor stations, pump columns, etc.
Offshore pipe applications - rolled and welded tubulars, cans, legs, piles, bracings, conductors, risers and tethers.
We cover the following applications for pipes for construction and steel structures under water:
Applications for machinery components include: felt rolls, wire rolls, press rolls, dryers, reel spools, winder drums, hydraulic cylinders, cable drums, yarn rollers, rolls for weaving machinery, cardan shafts and dryer rolls.
Based upon market research and customer requirements, EBK has developed new products based on existing materials. EBK has created their own trade marks for products which are far more enhanced than current standards which offer clients new possibilities for engineering and design work.
EBKPower provides the production of heat resistant steel pipes for power stations. In 1999 EBK was the first company to supply welded Gr. 91 for a hot reheat system in a power plant in India. Years of experience in the production of such materials and detailed knowledge about material behaviour gives great confidence to EBK's customers.
Based on cooperation with one of the world's largest producers of metallurgical bonded clad plates, EBK supplies welded clad plates to the market. Using the electro slag-welding method EBK is able to produce large tonnages for offshore and onshore applications. Additionally, weld overlay on the inner and outer surface of the pipe can be offered.
Base materials in various carbon steels, according to ASTM and API are used, with cladding of alloy 625, 825 or stainless materials like 304L, 316L and 904L. Other combinations are also possible.
The latest development EBK has introduced is the manufacture of welded pipes for cryogenic applications. This requirement comes from an ever expanding market for transportation and storage of Liquified Natural Gas (LNG). New receiving and loading terminals require substantial quantities of steel pipes usable at cryogenic temperatures.
Ni based materials satisfy these requirements, but non availability of weld filler metals created difficulties in using them effectively. EBK now has enhanced weld methods and can offer pipes with longitudinal and circumferential welds with overmatching mechanical values to the base materials. So today the industry can revise the established design calculations for nickel steels up to 36% Ni.
During 2007 EBK successfully supplied the first 9% nickel pipes used as pump columns inside an LNG storage tank for a project in Saudi Arabia. The benefit of nickel enriched materials include higher mechanical strength as well as much lower coefficient of thermal expansion as opposed to stainless steel pipes as used so far.
Consequently expansion loops on top of a jetty are no longer necessary and sub-sea pipe-in-pipe systems can even do away with the whole jetty. Using 9% and 36% nickel steels gives great economical, commercial and environmental benefits to projects worldwide.
