T/CSTM 01311-2025 Underwater wellhead equipment and production tree equipment coating salt spray corrosion test method
Basic Information
Scope
Scope: This document specifies the neutral salt spray corrosion test for coatings on underwater wellhead devices and production trees, including the principles of salt spray testing, salt spray testing equipment, salt spray testing solutions, sample preparation and placement, salt spray testing conditions, salt spray testing preparation, sample treatment after salt spray testing, coating adhesion testing, coating C-scan testing, acceptance requirements, and test reports, etc. This document is applicable to the detection of discontinuities such as pores and other defects in metals and alloys, metal coatings (anodic or cathodic), conversion films, anodic oxide films, and organic coatings on metal substrates of underwater wellhead devices and production trees and other related equipment.
