Elastomers 1

[aiwa7777]

Our application falls under the scope of NACE MR0175/ISO 15156.

Which standard provides (a) the list of acceptable elastomers and other non metallic materials suitable for sour service ? (b) Maximum H2S limit (ppm, H2S partial pressure etc) for elastomers ?

Thank You.

There are no publicly available standards that provide the information that you request. There are standards that detail how to determine the information such as NORSOK M-710 and ISO 23936-1.

Thank you Mr. Steve Jones.

I always appreciate your comments.

ISO 23936 has two parts, one for thermoplastics (ISO 23936-1) and one for elastomers (ISO/DIS 23936-2). You can purchase the latter, but technically it is still under development. The content will be substantially the same as NORSOK M-710.

Do not use NBR in sour service. NBR is a very common elastome used un industry, but is not suitable for soir service.
