Pipe fabrication and prefabrication of pipe systems

Complete supplier of pipe systems and spools.

Nordic Steel delivers complete solutions within pipe fabrication and pipe spool prefabrication – from technical review and engineering, to production and delivery of finished systems. We manufacture pipe systems according to customer specifications, industry standards and ISO drawings, for use in industry and process plants for offshore and energy, as well as on maritime installations.

By prefabricating in our own production halls, we ensure high quality, good documentation and reduced installation time for you as a customer, on-site. This gives our customers better control, fewer errors and more efficient projects.

Piping fabrication

We prefabricate piping systems in rust-resistant materials, and on request carbon steel (black steel) – this includes all necessary pipes, fittings, flanges, bends, transitions and special items. We supply both individual pipe spools and complete piping systems with electronic measurement, marking, documentation and pressure testing on request from the customer.

  • Production based on ISO drawings and P&ID
  • Welding according to ISO 15614-1 and M-601:2016
  • Certified welders according to NS-EN ISO 9606-1
  • NDT, pressure testing and full technical documentation
  • Pipes in all dimensions – all the way down from DN15 to DN1000+
  • Project management, material procurement and traceability
  • Deliveries to onshore and offshore projects

From drawing to finished pipe spool

We have extensive experience with technical review and adaptation of production documentation. Our own technical department assists when needed with drawing preparation and layout optimization. We place great emphasis on:

  • Interaction with the customer from start to finished delivered product
  • High delivery precision and documented quality
  • Fast response time and high production capacity
  • Efficient logistics and secure deliveries

Advantages of prefabricated pipe systems

  • Shorter installation time on site and offshore
  • Reduced risk and better HSE – less work in the field
  • More precise and efficient production with high repeat quality
  • Flexible deliveries – from simple spools to complete modules
  • Better cost control and fewer changes

Quality, certifications and professional expertise within pipe fabrication

When you choose Nordic Steel for pipe fabrication, you get a partner with high professional expertise and documented quality.

Nordic Steel is certified according to ISO 3834-2 , and we have our own in-house welding department with welding engineers (IWE and IWT) and welding inspectors with extensive technical knowledge, who assist with procedures for customers' projects.

We have a wide range of qualified welding procedures approved by accredited third parties , and regularly produce piping systems according to:

  • NORSOK M-601 (and other relevant standards)
  • NS-EN ISO 15614-1 level 2
  • ASME IX
  • NACE
  • PED

We adapt to customer requirements and are happy to add new welding procedures when needed. We are capable of most things and deliver to all standards and the strictest quality requirements. See all certifications . When it comes to piping, our products are manufactured and certified according to specifications that satisfy NORSOK, NACE and PED.
