Steel pipe wrapped around the outside of the cold corrosion petrolatum with job specification
1 Scope
This standard specifies the outer surface of steel pipes and shaped pieces (such as flanges, valves, tees, crosses, etc.) with anti-corrosion petrolatum belt wrapped around the cold
Corrosion resistant construction materials requirements, design, construction and inspection.
This standard applies to the atmosphere (including humid environment) in the anti-corrosion steel pipes and shaped pieces of external anti-corrosion layer of petrolatum tape wrapped around the cold
Construction and other suitable cold profiled steel structure wrapped with the use of substandard petrolatum corrosion may also refer to the implementation of this standard.
