thermoplastic materials at -150F
(OP)
Hi, We are manufacturing at present plastic pipe for oil and gas industry. Guys can you suggest me which thermoplastic materials will be good at -150F. We will make pipe from these materials.
Also please suggest about thermoset polymer.
thx a lot.

Coldest temperature recorded on Earth was -89.4C (-128.9F) in Antartica.

Thx UWH for giving me those links. But they will be transfering CNG and its not only the ambient temperature and so forth and it also has to deal with the product itself.
RE: thermoplastic materials at -150F
I think the ambient temperature direction was initiated by your response of "for alaska" to my question of "What is the application in the oil and gas industry that is going down to -150 °F? ".
If you responded initially with trasport of CNG, I think the direction would not have gone in the ambient temperature direction.

i would not recommend/be buying plastic pipe for CNG service in alaska, especially if there is no substantial design and in-serivce data to support the use of such pipe. too many design considerations, of which, seismic is a critical factor.
good luck!

There are some looking at semi rigid polymers for very low temp services:

Whether that has compatability with the CNG and its minors, I couldn't guess...
There are PTFE-Jacketed HD hoses that will handle high pressure at low temperature, the Cryo people use a flock of them, but the only thing they use in rigid pipe is a high nickel stainless

From my sources, of the various unfilled fluoroplastics, only PTFE and PFA have brittleness temperatures as low as -200oC.
