What is ISO 18797-2 - External corrosion protection of risers by coatings and linings about?
ISO 18797-2 specifies the selection criteria and minimum requirements for a protective coating systems for maintenance and field repair of risers exposed to conditions in the splash zone.
Note: ISO 18797-2 does not apply to the selection of techniques and materials used to restore the integrity of the risers to be coated, nor does it apply to the selection of additional mechanical protective materials that are not part of the coating systems described in ISO 18797-2.
Who is ISO 18797-2 - External corrosion protection of risers by coatings and linings for ?
ISO 18797-2 on external corrosion protection of risers by coatings and linings use is beneficial for:
- Drilling engineers, energy engineers, mining engineers, petroleum engineers, petrochemical engineers, and corrosion engineers
- Engineering geologists
- Geochemists and geophysicists
- Geoscientists
- Hydrographic surveyors
- Petroleum officers
- Natural gas producers
- Workers of coatings and linings
Why should you use ISO 18797-2 - External corrosion protection of risers by coatings and linings ?
Corrosion protection is the application of anti-corrosion chemicals to prevent damages to equipment or facility caused by corrosive agents.
ISO 18797-2 has been developed in response to worldwide demand for minimum specifications for field applied maintenance and repair coatings for riser pipes.
ISO 18797-2 benefits the user for the maintenance and repair of coatings on other types of structures in the offshore splash zone, such as jetty piles and platform legs. ISO 18797-2 does not limit the contractor or the manufacturer from proposing, or from accepting, alternative engineering solutions for the individual application. ISO 18797-2 is applicable where there is innovative or developing technology, where an alternative is proposed, the specification issuer is expected to identify any deviations from ISO 18797-2 and provide details. ISO 18797-2 is applicable for maintenance requirements and field repairs of riser coatings.
Overall, ISO 18797-2 is helpful as it assists the user with the maintenance and field repair coatings for riser pipes which can help you in your business. ISO 18797-2 retains or restores the integrity of the existing coating in order to reach a level of protection against corrosion that enables a metallic structure to continue in service operation safely and economically for a determinate period.
