All external surfaces and welds can be cleaned by a wet passivation at nitric acid, we can offer:
Local weld paste passivation or
Complete surface passivation applied by spraying
The internal corrosion resistance can be suited by choice of purging gas type, we are qualified for following types:
All piping is visually inspected:
Customers commonly order a dye penetration testing on butt welds
