Description of Industry Use Case
Alloy 20 Pipes and Tubes offer an excellent level of resistance against sulfuric acid, chlorides and stress corrosion cracking and are therefore very favorable in chemical and petrochemical industries. They can be easily fabricated due to their formability, and safely handled aggressive media under pressure by mechanical strength. The Alloy 20 pipes are being installed in most industrial systems along with compatible fittings and flanges to build leak free flow systems. B2B sourcing environment is usually characterized by the need to trace materials, conduct tests, and meet international standards in the sourcing process to offer strong performance in corrosive service conditions.
