Process for constructing and anchoring a pipeline.

摘要

The invention relates to a pipeline comprising a tube (10) anchored to a sleeve (12). The pipeline includes anchorings wherein a compression ring (26) is clamped between an internal stop (14) integral with an internal tube (10) and an external stop (20) integral with a sleeve (12). Said compression ring (26) has good thermal insulation and compression resistance properties. Considerable longitudinal stresses can thus be transmitted between the tube (10) and the sleeves (12). The invention is intended for building underwater pipelines transporting cold products such as liquified natural gas and liquified oil gas.
