A-106 B is most often quadruple certified to include A53 B seamless, API 5LB seamless and API 5LX42 seamless.

RE: WELDING GRADE BPIPE WITHE API X-42 ISOLATION JOINT

A 106 Gr.B specified for using special in high tempreture service , but API 5L for pipe line . if your system works in high temp. over 500 celeze. you can not use API 5L , if you use normal temp. it is permit to use ( same in mechanical & chemical specification)
