Design of HDPE Stub end for PE lined carbon steel pipes in Oil&Energy

[ram0608]

Hi! We design HDPE Stubend(s) for use of HDPE Lined carbon steel pipelines application. We provide stubend collor thickness (flange face thickness) double of pipe thickness. In recent conversations, we came to knew stubend flange face thickness 1 to 1.5 times of pipe thickness is sufficient. We would like to know what will be the idle flange face thickness or flange dimensions without effecting the application. (HDPE lined carbon steel pipelines or spools) Photo of HDPE Stubend attached for reference.

Thanks in advance.

Probably a question best posted in the pipelines and piping engineering forum (mechanical engineering section).
