Abstract
Techniques for implementing and/or operating a system that includes an outer pipeline, an inner pipeline, and an outer pipeline sealing mechanism. The outer pipeline includes an outer pipe fitting to be secured to an end of an outer pipe segment. The inner pipeline includes an inner pipe fitting to be secured to another end of an inner pipe segment. The outer pipeline sealing mechanism includes a sealing plate to be secured to the outer pipe fitting; a sealing stem that extends out axially from the sealing plate, in which the sealing stem is to be secured to the inner pipe fitting to facilitate sealing an inner pipeline bore from an outer pipeline bore; and a seal ring to be compressed between the sealing plate and the outer pipe fitting to facilitate sealing the outer pipeline bore of the outer pipeline from external environmental conditions.
