Anti-corrosion of pipelines in high-pressure hydrogenation units

2012-07-18View Original

Thread Content

The reactors in high-pressure hydrogenation units are made of chromium-molybdenum steel, and a double-layer surfacing is also applied to the surface of the reactor base metal. Then does the inner wall of the export pipeline also need to be surfaced with cladding? Should the heat exchanger tube bundle right next to the outlet also be cladded?

Hey OP, take a look and see if this standard is useful to you: ^SH 3520-04| Welding Procedures for Chromium-Molybdenum Heat-Resistant Steels in the Petrochemical Industry.
