Pre Qualified WPS joint detail HELP

By obowhunter2 Date 01-29-2020 21:29

Good afternoon,
I am going over WPS's for the company I am currently working for and found some Pre Qualified WPS's they are using. I am questioning the joint design used. It list
T-PF-G under the joint design used. Could someone clarify this for me. I can not find this in D1.1 in the pre qualified joint details.

Without looking through D1.1, at first glance I would speculate it to be their own designation and not something from D1.1 Clause 3 Figures. That is not prohibited and leaves you to find out where they have a master chart that defines their abbreviations.

Have a Great Day, Brent

obow,

It’s possible that the details for the joint designation they used, matches the same details for a prequalified joint. If that’s what they’ve done, in my humble opinion, they should have at least referenced the prequalified joint designation in D1.1
