Is there a significant difference between ASTM A106 and A105 materials?
Thread Content
Our original valves are made of ASTM A106 steel, which is used in natural gas processing facilities. The maintenance staff is planning to purchase valve spare parts made of A105 steel with a corrosion allowance of 3 mm. I wonder if this will work?
There are significant differences between ASTM A106 and A105 materials. ASTM A106 is a standard specification for carbon steel seamless pipes, used in pipelines under high temperature and pressure conditions, whereas ASTM A105 is a standard specification for carbon steel forgings, used in the manufacture of valves, flanges, and other equipment. Due to their different applications, there are significant differences in their chemical composition, mechanical properties, and heat treatment requirements. Therefore, if the raw material for your valve is steel per ASTM A106, it is best to choose spare parts of the same material to ensure compatibility with the original valve and avoid safety hazards. If A105 steel is used as spare parts, a professional assessment is required to ensure that it meets the requirements and safety standards of natural gas processing facilities. .
May I ask: What are the corresponding domestic material grades for the American standards A106, A105, and A234? https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=656414&shareuid=4554153
