Sour Gas (H2S) Resistant Elastomers

Sour Gas (H2S) Resistant Elastomers. Sour gas containing hydrogen sulfide/sulphide (H 2 S) can have very detrimental effects on elastomers. Non-resistant elastomers will become hard and brittle, losing their elastic properties and their ability to seal, ultimately leading to seal failure. PPE has developed a number of sour gas resistant elastomer materials for the oil, gas and petrochemical processing industries with Sour Gas - Ariel CorporationFor sour gas service with 100 ppm and greater H2S content stainless steel piston rods are required. Ariel stainless steel piston rod material is 17-4PH in the double H1150 condition, UNS S17400, (per NACE MR-0175), Rc 33 maximum, chromium-nitrided in the packing travel area
