ISO23936-2 & NORSOK M710 Elastomers

ISO23936-2 and NORSOK M710 seals designed and manufactured to face the harsh operating conditions of upstream exploration and production applications.

ISO 23936-2 “Petroleum, petrochemical and natural gas industries – non-metallic materials in contact with media related to oil and gas production” was prepared by Technical Committee ISO/TC 67. ISO 23936 (Part 2: Elastomers) describes the requirements and procedures for qualification of elastomeric materials used in equipment for oil and gas production.  It provides general principles, requirements and recommendations for the selection and qualification of non-metallic materials for service in equipment used in oil and gas production environments, where the failure of such equipment could pose a risk to the health and safety of the public and personnel, or to the environment. It can be applied to help avoid failures of the equipment itself. 

The NORSOK M710 standard defines the requirements for critical elastomer sealing, seat and back up materials for permanent use subsea, including well completion, X-mas trees, control systems and valves. The standard also applies to topside valves in critical gas systems and ensures adequate safety, added value and cost effectiveness for existing and future petroleum industry developments.

There are two relevant parts to the NORSOK standard:

  • Annex A – Test media, conditions and procedures for ageing of elastomeric materials (sour gas)
  • Annex B – Resistance to rapid gas decompression (RGD) – also known as explosive decompression

NORSOK M710 is an internationally recognized standard (developed by the Norwegian Petroleum Industry) that sets out the qualification requirements of non-metallic sealing materials and manufacturers. 

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies. International Standards are prepared by ISO technical committees that focus on and represent a particular area of specialty.

Products

PPE’s ISO23936-2 and NORSOK M710 certified elastomers can molded into infinite shapes and profiles to suit any application.

Elastomer O-Rings

Fully molded elastomer O-rings for critical sealing applications. Standard and custom sizes available.

X-Rings Quad Rings

X-rings offer an alternative sealing solution to O-rings for a wide range of reciprocating or rotary applications.

T-Seals

T-seals – with T-shaped cross section and two backup rings – offer an excellent sealing solution for static or dynamic applications.

Spring Seals

For applications where large clearance gaps or bi-directional pressures are a factor, consider the effectiveness and strength of a PPE spring seal.

FS Seals

FS seals are a double acting static seal designed for use as casing and tubing hanger seals in wellheads.

Lip Seals

Energized lip seals comprise of a high modulus elastomer jacket and a low modulus elastomer O‑ring energizer.

Chevron Stacks

Chevron stack sets are multi-lip packings which are especially suited to mechanically-challenging conditions.

Production Packers

Production packers are a downhole sealing device which is used to isolate the annulus from the production conduit, enabling controlled production, injection or treatment.

ESP bags

An electric submersible pump (ESP) is used in oil wells to pump fluids to the surface. Discover more about ESP bags here.

Custom Seals

PPE designs and manufactures custom molded rubber parts and bespoke engineered components to meet any sealing requirement.
