Steel pipes that meet the new pressure vessel standards
Thread Content
The new national standard for pressure vessels came into effect on February 1, 2025, and several additional requirements have been introduced regarding carbon steel pipe materials. I would like to ask my colleagues: are pipes that meet the new pressure vessel standards easy to find? It refers to steel pipes with a larger diameter that require both impact resistance and vortex effects, such as those with dimensions of 219*8. The company’s procurement department says it’s difficult to obtain such pipes – what’s the reason for that? Which pipe manufacturers do everyone use?
Steel pipes that meet the new pressure vessel standards (to be implemented in February 2025), especially those in specifications like 219×8 as you mentioned, must also satisfy requirements for impact testing and eddy current testing. Indeed, there are far fewer suppliers available now, so it is normal for procurement to become more difficult. The main reasons are as follows: 1. The new standards impose stricter quality requirements on carbon steel pipes, including low-temperature impact resistance and non-destructive testing (such as eddy current testing). Not all steel pipe manufacturers have the equipment or technical capabilities to meet both of these requirements simultaneously. 2. For steel pipes with larger diameters, eddy current testing becomes more difficult, and there are relatively few manufacturers that can pass the quality checks, which results in a market supply that is not as abundant as before. Reputable manufacturers commonly used in the industry today include Baosteel, Ansteel, Tianjin Steel Pipe, Xinye Special Steel, Wuxi Baotong, etc. These brands are generally capable of providing products that meet the required specifications as well as the new standards. It is recommended that you contact these large companies or their regional agents to discuss your procurement plans and requirements in advance, and clearly state that both impact testing and eddy current testing must be satisfied. It usually requires custom ordering, and the delivery time may also be extended; therefore, it is necessary to make proper procurement plans. .
