As experts in the production of pipelines for the diverse needs of various industrial sectors, we offer you a wide range of individual solutions. Here you can find more information about our products.

Workshop production of pipespools

We produce pipespools made of metals according to our customers’ isometric drawings conform to international standards for all kinds of applications in plant construction and shipbuilding on a 5,000 m2 hall area in our works in Bremen. We supply complete piping ready for installation, including the required works inspections and surface treatment. We hereby trust long-term, well-qualified partners.

Our production workshops have modern, complex equipment with NC flame cutting and bending machines, the latest welding technology through to automated welding, which enable high-quality products and short delivery times. Our own workshop engineering, production planning and international procurement contribute to a high degree of flexibility and our own controls over the entire manufacturing process.

We virtually exclude the formation of alien corrosion and ensure quality by consequently separating CrNi and Cunife-steel processing from the black steel departments. In addition, quality and traceability of the processed materials are ensured by clearly described processes.

  • Stainless-steel 1.4307, 1.4571, 1.4404, ASTM 304L, ASTM 316L
  • Duplex 1.4462
  • CuNiFe 2.1972.11 and 2.1972.22
  • Copper

Dimensions:

  • Diameter from DN 8 to DN 1000, larger diameters available on request
  • Wall thickness: from 1 mm to 20 mm

Machine processing:

  • Plasma cutting up to D= 1016 mm and width= 25 mm
  • Mandrel bending DN 8 (10.0) up to DN150 (168,3)
  • Extruding up to DN 150 (168.3) for the extrusion, main pipe diameter up to DN 400
  • Beading up to DN 150 (168.3)

Double-walled pipelines for gaseous and liquid fuels in sensitive surroundings

We supply efficient solutions for cryogenic applications – from the detailed design and material procurement through to production, testing and fitting. Both design ready for production and use and the well-qualified production and testing of the pipelines are performed in our own works. 100 % traceable processing conform to accepted production processes and the procurement of the accordingly tested materials guarantee that the components are used safely and reliably.

  • Double-walled piping for LNG systems on ships and in land-based plant construction according to international standards and specifications
  • Design ready for production and use in our own works and our own well-qualified production and testing of the pipelines

Materials:

  • Carbon-steel (P235 to P355)
  • Stainless-steel 1.4307, 1.4571, 1.4404, ASTM 304L, ASTM 316L
  • Operating temperatures up to -196°C

Production of functional modules

As pre-assembled system components or as Plug & Play, we produce all kinds of modules in accordance with our customer’s specifications:

  • Heat exchanger modules
  • Pump modules
  • BWTS modules
  • Fire extinguisher system modules
  • Gas control lines
  • Distribution lines
  • Pre-assembled pipe runs

Steel construction, pipeline building, assembly, electrical cabling and colour coating through to testing and FAT are performed in-house in Bremen. We have a separate, 1,000 m2-sized assembly hall with storage space for plant parts supplied to us. Packaging for shipment as required, also suitable for international sea-going transport.

Experienced project managers control orders in line with adapted production and assembly plans. Our quality assurance department checks procedures and end products with regard to the characteristics agreed in the contract.
