T/SCMES 8-2020 Petroleum and natural gas drilling equipment: Specification for water-based coating of drilling machines
Basic Information
Scope
Main technical content: This document specifies the design requirements for corrosion protection of water-based coatings on the outer surface of steel substrates of oil and gas drilling and extraction equipment under corrosive environments, the performance requirements and test methods of coatings, the evaluation of coating processes, the requirements for coating application, the requirements for coating inspection, and common colors. This document is applicable to the application of water-based coatings on the outer surface of steel substrates of oil and gas drilling and extraction equipment under atmospheric corrosion types C3 (moderate) and C4 (severe). This document is not applicable to the application of water-based coatings on the outer surface of steel substrates of oil and gas drilling and extraction equipment under atmospheric corrosion types C5 (very severe) and CX (extreme).
