Name : WB36 (T36/P36, 15NiCuMoNb5-6-4) HOT ROLLED TUBES FOR HIGH TEMPERATURE AND PRESSURE APPLICATIONS​


Definition :

WB36 is a bainitic Ni-Cu-Mo steel micro-alloyed with niobium. It is also known as 15NiCuMoNb5-6-4 according to EN 10216-2 and VdTÜV377/2, T36 according to ASTM A 213 and P36 according to ASTM A 335.

Application:

This grade is mainly used in high-pressure, medium-temperature feedwater lines (close to 400 °C).

Challenges :

WB36 exhibits excellent high-strength properties up to 450 °C. The reduced weight of the feedwater piping components compared with conventional carbon steel allows improved resistance to thermal fatigue and very good heat transfer.

Key advantages of Best Pipeline include:

  • Production and delivery of our own steel products, especially boiler pipes made of X10CrMoVNb9-1 and X10CrWMoVNb9-2 grades as well as other materials designed for high-temperature service
  • Design of the boiler parts, pipeline elements, Y-fittings and T-fittings
  • Prefabrication and assembly of boiler and industrial piping
  • Services:
    • technical consultations on preparing delivery, production and assembly contracts/agreements in order to provide a constant control/inspection over fulfilling the requirements listed in the “Delivery Technical Conditions” and “Construction and Commissioning Requirements”.
    • inspection and control over technological processes as per contracts/agreements in order to assure their realisation within the agreed time, cost reduction and quality of the final product
    • examination and testing followed by the final acceptance performed by the Notified Bodies. Additional creep tests of materials designed for the high-temperature service
    • free of charge preliminary examinations of pipelines in service using a portable SFM to determine their life assessment and evaluate the necessity of repairs, modernisation or further investments.
