NACE Certified Seals

There are two NACE standards focused on elastomer materials used for O-rings and seals:-

• NACE TM0187 - Elastomeric materials in sour gas environments
• NACE TM0297 - Effects of high temperature, high pressure carbon dioxide decompression on elastomeric materials.

NACE TM0187 provides a test method that measures the ability of elastomeric materials to withstand static exposure to elevated pressure and vapor-phase sour gas environments (e.g., gaseous hydrocarbons with hydrogen sulfide) and is not designed to be an immersion or functional test. It is designed for testing O-rings or specimens of elastomeric vulcanites cut from standard sheets.

NACE TM0297 presents test procedures to measure the effect of rapid depressurization from elevated pressures and temperatures in dry CO₂ environments on elastomeric materials. Includes sections on the preparation of test specimens and equipment to be used, test procedures to be followed, and procedures for reporting results. 

NACE elastomer materials

PPE offers a number of material grades that have been tested and certified to NACE standards, including HNBR, EPDM, FEPM, FKM and FFKM.  This comprehensive range gives engineers the opportunity to match a sealing material to their operating environment according to temperature, pressure and chemical media.

PPE's NACE certified elastomer materials can be molded into infinite shapes and profiles to suit any sealing application; O-rings, X-rings, T-seals, chevron stacks, lip seals, wiper seals, spring seals and custom seals.
