can someone please tell me why a nozzle and gate valve have same symbol in p&id, and how can we differentiate them? and also can someone post a guide how to read fabrication iso drawing and p&id complete symbol char
unfortunately we dont have wps for groove weld or any.we're just going to make fillet weld on pipe n flanges. I know that butt weld need to have minimum tensile strength of base metal, what is criteria for fillet weld alone to qualify? what should be the size of throat, how can we make sure that...
I want to write a preliminary wps for flange (MS thickness 20mm) to a pipe ( MS thickness 8mm), i was referring to D10.12M/D10.12:2000, Guide for Welding Mild Steel Pipe. but there is no information on fillet weld. Do we have to run tensile and bend test on test coupon?
