Must ethylene oxide pipelines use foam glass as a insulation material? If so, could you please tell me which **standard or industry guideline specifies this? Thank you!
Notice on Strengthening the Safety Management of Storage and Transportation Containers for Ethylene Oxide, Number: Zhiji Jian Guo Zi 95 – Clear provisions are outlined therein
This standard applies to ethylene oxide tank trucks; are there similar regulations for ethylene oxide pipelines?
But our company uses foam glass for the insulation of ethylene oxide pipelines, rather than polyurethane.
Although foam glass has an A-grade fire resistance rating, it has a very high thermal conductivity, which results in high energy consumption; moreover, it is brittle and suffers from high losses during installation.
