Tailored hot-rolled steels for durable and robust line pipes to carry water, oil, gas and hydrogen

Tailored hot-rolled steels for durable and robust line pipes for the conveyance of water, oil, gas and hydrogen.

Steels for welded line pipes for the conveyance of water, oil and gas as well as for the distribution of hydrogen and carbon dioxide must meet special requirements depending on the medium to be transported.

Be it operating pressures of over 100 bar, abrasive wear, extreme temperatures or temperature variations, permanent mechanical stress – the primary requirement characteristics and the specific material properties required as a result in terms of strength, toughness and chemical composition are as varied as the possible applications of welded pipes.

thyssenkrupp Steel supplies special steels for all applications of line pipes:

  • Line pipes of product class PSL 2 according to API 5L/DIN EN ISO 3183 with or without optional Battelle drop weight tear test (DWT test)
  • Water tubes according to EN 10224 and API 5L PSL 1
  • Oil country tubular goods (OCTG) according to API 5CT
  • CO2 transportation pipelines according to ISO 27913
  • Sour service pipes according to API 5L, Annex H
  • Pipes for the transport of hydrogen according to EIGA Guideline
  • Structural pipes and hollow sections according to DIN EN 10219-1 and API 5L PSL 1

If you need information about any other steel grades, applications or dimensions, our experts will be happy to assist you.

Line pipes for oil and other flammable liquids, natural gas and other gaseous media

The oil and gas industry uses pipelines as a safe means of transporting oil and gas over long distances. Steel is the ideal material for pipeline transportation systems in terms of safety, reliability, robustness and durability. Our pipe steel grades for line pipes used to convey liquid and gaseous media are available in normalized or thermomechanically rolled delivery conditions. Apart from a low carbon content and the resulting good weldability, thermomechanically rolled pipe steels feature excellent toughness properties - an important characteristic for pipes that have to withstand high operating pressures.

Aside from the standard grades for oil and gas pipes, our portfolio also includes special steels for media contaminated with hydrogen sulfide (H2S) in accordance with API 5L, Annex H, and DIN EN ISO 3183. In our in-house corrosion laboratory, which is accredited according to ISO 17025, DaKKS and ARAMCO, we carry out corresponding tests for sour gas resistance according to common NACE regulations.

For the hydrogen infrastructure of tomorrow: H2-optimized steels for safe and durable pipeline transportation systems

Apart from the low-alloy steel grades X42 and X52 which are suitable for the transport of gaseous hydrogen and hydrogen mixtures in accordance with EIGA Guideline IGC Doc 121/14, our range includes optimized material concepts for the strength range up to X70. These steels are optimized with regard to the expected standard requirements of longitudinal and spiral welded pipes for the transport of hydrogen, in particular with regard to restricted contents of carbon, phosphorus and sulfur.

Bring on the water – Steel line pipes for water management

Be it for industrial or wastewater, cooling water, other aqueous liquids or even drinking water (cf. EN 10224) - supply by means of steel line pipes is the optimum solution in terms of cost-effectiveness and safety. Another field of application is district heating pipelines for high pressure loads in accordance with DIN EN 10217. Thanks to their high degree of purity in combination with a matching chemical composition, the steel grades are ideal for welding for the two applications.
