ActivePetroleum, petrochemical and natural gas industries—External corrosion protection of risers by coatings and linings—Part 2: Maintenance and field repair coatings for riser pipes
石油、石化和天然气工业 用涂层和包覆对立管的外腐蚀防护 第2部分：立管防腐层的维护和现场修复
Application Summary AI generated
This standard specifies technical requirements for the maintenance and field repair of external corrosion protection coatings on riser pipes used in the petroleum, petrochemical, and natural gas industries. It applies to on-site coating application and repair procedures for risers in offshore platforms, subsea systems, and coastal facilities where corrosion protection must be restored or maintained without removing the pipe from service. The standard ensures that field-applied coatings meet performance criteria for adhesion, thickness, and environmental resistance in harsh marine or industrial environments.
