Title:
INSULATED PIPE JOINT
Document Type and Number:
WIPO Patent Application WO2007103059
Kind Code:
A9
Abstract:
A pipeline (20) that lies primarily in the sea and that consists of multiple steel pipe sections connected in tandem at pipe joints, includes a protective coating around the pipe sections and around the pipe joints. Each pipe section is first covered, at an onshore facility, by an initial coating (30, 32) that extends along at least 80% of the pipe section length while leaving its ends uncovered, to leave gripping areas (40, 42) where the steel of the pipe is uncovered so the pipe can be clamped by tools such as those with steel jaws to position and slide it axially, or turn it, or prevent it from turning. After a pair of pipe sections are connected, a completion coating (50) is applied around the pipe joint to leave the pipeline with a coating around all of it.
