Article 6.2.1 of the General Rules for the Selection of Materials in Petrochemical Pipeline Design: For pipes with a nominal diameter of 40 mm or less, socket welding is recommended; however, socket welding should not be used for pipes exposed to media that may cause intergranular corrosion. Question: What are the media that may cause intergranular corrosion?

Wet H2S counts as one. Last edited in this post by pipe200 on 2007-12-25 17:14]

In most cases, it is CL ions; generally, they are ions, especially in humid environments
