Joint efficiency & Radiography - API 650
Joint efficiency & Radiography - API 650
(OP)
What is the relationship between Joint efficiency and Radiography per API 650 ? Can a Joint efficiency of 1.00 be used for design and Spot radiography be applied during construction. What is the normal engineering practice ?





RE: Joint efficiency & Radiography - API 650
There are two additional options available when specified by purchaser. Appendix A uses less RT than the basic Standard with E = 0.85. When no RT is performed E = 0.70.
The term "joint efficiency" is probably not the best term to use. Perhaps "quality factor" would be better, but that's another topic.
