Shanavas,

>what does WPB stands for in case of fittings?

Before posting this forum it is not smart to do a quick search within this forum for similer previous postings?

Hope you will be smart next time. Hope all other freshers take a tip from this.

Here is my posting on this forum 1st Aug 2006

Pradeep,

Visit the following link, where this subject was discussed 3 years ago…. http://www.eng- tips.com/ viewthread. cfm?qid=66063& page=8 The following links also give good info....

PAGES/A815A815M. htm?E+mystore

From all those discussions, I could summarize the issue as.. ASME does not define what is “WP” or “WC” anywhere…. As long as ASME does not define these terms, I would like to use the following best terminology. .

First two digits:
WP stands for Weldable & made from Pipe
WC stands for Weldable & made from Casting

Next digits: Example
A/B/C stands for items equivalent to grade WPB, WPC S stands for Seamless Construction WP-S
W stands for Welded fittings WP-W
WX stands for all welds are 100% radiographed WP-WX WU stands for all welds are 100% ultrasonically tested WP-WU L stands for low temp service WPL6 (Here 6 denotes 60 ksi strength)

There are few “Code Guru’s” in this group. Hope they will substantiate my terminology…
