BS EN 10225-4:2019

What is BS EN 10225-4 - Weldable structural steels about?  

BS EN 10225 is a series of European standards on weldable structural steels that discusses its technical delivery conditions.  

BS EN 10225‑4 is the fourth part of a series of documents. BS EN 10225-4 specifies requirements for submerged arc welded (SAW) and high frequency welded (HFW) cold-formed hollow sections to be used in the fabrication of fixed offshore structures. 

Who is BS EN 10225-4 - Weldable structural steels for?  

BS EN 10225-4 on Cold formed welded hollow sections is beneficial for 

• Welders/ fabricators 
• Structural engineer 
• Steel manufacturer 
• Non-destructive testing personnel 
• Metallurgist 

Why should you use BS EN 10225-4 - Weldable structural steels?  

As Cold-formed high frequency welded (HFW) Hollow sections were not previously been permitted for offshore use, people were not aware of the requirements. 

BS EN 10225-4 assist the user by providing Technical delivery conditions and guidelines  required for Cold-formed high frequency welded (HFW) Hollow sections for offshore which assist the user in safely carrying out the work 

BS EN 10225-4 navigates you through the manufacturing process of steel which helps the manufacturer to produce steel according to the requirement. In this manner, you can manufacture high-quality products and build customer trust. 

What’s changed since the last update?  

BS EN 10225-4 supersedes EN 10225:2009. 

In comparison to the previous edition following technical changes were made: 

• In the previous edition, it was specified that only hot finished HFW or seamless hollow sections could be used offshore. However, EN 10225‑4 now also allows the use of cold finished HFW hollow sections 
• Information on Prequalification of steels for offshore structures operating in arctic areas is added 
• In the previous edition, only requirements for the plate but not structural hollow sections produced from the plate were included. As submerged arc welded (SAW) structural hollow sections produced from the plate are used extensively in offshore applications, it is included in BS EN 10225-4
