Temperature Limitation to Liquid and Gas piping
Temperature Limitation to Liquid and Gas piping
(OP)
I would like to apologise before I start my question again. I had asked this question in my other post in a different section. Please pardon me if this is a violation.
The temperature derating factor provided for ASME B31.8 stops at 450'F.
Does this mean that gas piping ( B31.8)can be designed only upto 450'F ?
Is there is temperature limitation to liquid and gas piping design ?

Misquoting was not my intention. I was just trying to cheat. I am from the manufacturing world. We have set out own boundaries where B31.4 and B31.8 have common guidelines. YOur statement has provided answer to the part that I was trying to cheat. Thank you.
But, my primary question remains unanswered.

Section 802.1 (b) This Code does not apply to
(1)
(2) piping with metal temperatures above 450F or below -20F.

I am trying to understand the scope for some piping components (adapters and housings for hot tapping). I do not design pipe lines. But, I have to assume that if a code allows something, there could be someone out there who may want to do it. However, I have to let my customers know of the specified limitations, when I deny manufacturing, when I feel the need and provide them the proper reference of my standing ground.
