Metengr, there is no need to read minds,it`s pretty simple. I`ve said it in as plain language as i can, but here goes again : "The 3 3/4" tests are not about diameter limits, it's about the amount of weld produced for inspection on a test piece." If you are not aware of such requirements all...
The 3 3/4" tests are not about diameter limits, it's about the amount of weld produced for inspection on a test piece. It has to be 80mm of weld at least to validate the test.
Thanks for the info Metengr. Have I not to test the welders on 3 3/4" to get the required amount of weld to be tested? We have used this method for quiet some time. Is it necessary at all?
We`re doing a plant/pump room (chilled water) with 10" carbon down to 3/4" carbon. Will a generic ASME IX WPQR do for this?? and correct me if I`m wrong a 6" 6G test will cover me up to 10"?? and 3 No: 3/4" will be needed to qualify me for the 3/4". Will I also need a 2" test to be done to...
