What is ISO 18797-1 - Elastomeric coating systems – polychloroprene or EPDM about?
ISO 18797-1 specifies the minimum requirements for materials selection, surface preparation,
application, inspection, testing, qualification and acceptance criteria of external coating for steel riser pipes used in the splash zone, their field joints and clamps/guides, using an elastomeric protective coating based on polychloroprene, EPDM or equivalent. This is applicable for new construction and repair of applied pipes before installation. Maintenance requirements and field repairs are covered in ISO 18797-2.
ISO 18797-1 also specifies the requirements for transportation, handling, and storage of riser pipes before and after surface preparation and coating application.
Note 1: This can be particularly applicable where there is an innovative or developing technology. Where an alternative is proposed, the specification issuer needs to identify any deviations ISO 18797-1 and provide details.
Note 2: ISO 18797-1 does not incorporate any form of passive fireproofing requirements or any related compatibility issues. Any requirements with regards to passive fireproofing are to be addressed separately.
Note 3: Users of ISO 18797-1 need to be aware that further or differing requirements can be needed for individual applications. ISO 18797-1 is not limiting the contractor and/or manufacturer from proposing or the company from accepting alternative engineering solutions for the individual application.
Who is ISO 18797-1 - Elastomeric coating systems – polychloroprene or EPDM for?
ISO 18797-1 on elastomeric coating systems – polychloroprene or EPDM is useful for:
- Petroleum, petrochemical, and natural gas industries
- Manufacturers and suppliers of elastomeric coatings
Why should you use ISO 18797-1 - Elastomeric coating systems – polychloroprene or EPDM?
EPDM (Ethylene Propylene Diene Monomer), is a synthetic rubber developed in the 1960s. The material's durability and flexibility make it useful in a variety of applications. It is particularly useful in applications such as hot and cold sealing, electrical enclosures, and HVAC systems.
ISO 18797-1 is based on GSO 2273. ISO 18797-1 defines the minimum technical requirements for the external corrosion protection of risers by coatings and linings based on elastomeric coating systems-polychloroprene, EPDM, or equivalent elastomeric coatings that are employed in the oil and gas industry.
ISO 18797-1 provides technical guidance for developing local standards and specifications in order to ensure compliance in coating and lining material selection and performance with contract requirements.
