Paragraph 4.5.4.5-（3) of TSG 11-2020, \"Technical Regulations for Boiler Safety\", stipulates that \"welded joints of pipes with elbows without straight sections shall be subject to 100% radiographic or ultrasonic testing.\" Then do the welds of those pipes and tees not need to have this barcode? Why are elbows and tees treated differently?

There are many parts of the new pot regulations that are hard to understand. This one is one of them. How should the testing ratio be determined in actual installation work?

State clearly that 100% flaw detection is performed
