ReplyDeletemay i know 1 more types of fluid.
ReplyDeleteWhat is the different type fluid in ASME?
ReplyDeleteReally helpfull. Thanks.
ReplyDeleteParfait les amis!
thanks sir, it s really helpful to us.

ReplyDeleteThanks
ReplyDeleteFor the following fluid service category listed above, how to decide its piping material when you are having the design? Also does ASME B31.3 have the tables for the equivalent materials to be use for each particular fluid service category?
