CRYOGENIC PIPELINE CONFIGURATIONS AND METHODS

摘要

A pipe-in- pipe pipeline has a bulkhead that transfers thermal stress from a n inner pipe to an outer pipe, wherein at least part of the bulkhead forms a conduit for a product traveling through the inner pipe. Most preferably, the pipeline is a cryogenic pipeline for transport of liquefied natural gas. Whe re desirable, insulating material may be disposed between the inner pipe and outer pipe, while spacers may maintain the distance between the pipes.
