Restraint system and method for high pressure pipeline
Restraints are used to restrain a pipeline having pipe segments coupled together in an end-to-end manner. A first restraint is coupled to first and second pipe segments, which are non-adjacent to one another. A second restraint is coupled to third and fourth non-adjacent pipe segments, wherein the third pipe segment is between the first and second pipe segments. The first and second restraints are coupled together at an overlapping portion.
1. A method of restraining a pipeline, the pipeline having pipe segments, comprising the steps of:
a) coupling a first restraint to a first set of non-adjacent pipe segments;
b) coupling a second restraint to a second set of non-adjacent pipe segments, with one of the pipe segments of the second set of pipe segments between the pipe segments of the first set of pipe segments;
c) overlapping a portion of the first and second restraint;
d) coupling the overlapping portions together.
2. The method of claim 1 wherein the step of coupling the first and second restraint to the first and second sets of non-adjacent pipe segments further comprises the step of coupling the first and second restraint near respective ends of the pipe segments with self-tightening loops around the respective pipe segment.
3. The method of claim 2 further comprising the step of securing the self-tightening loops from enlarging.
4. The method of claim 1 wherein the step of coupling the overlapping portion of the first and second restraints together further comprises coupling the overlapping portions with a ring.
5. The method of claim 1 further comprising the steps of:
a) coupling a third restraint to a first set of non-adjacent pipe segments and to an anchor so as to overlap a portion of the third restraint with the first restraint;
b) coupling the overlapping portions of the first and third restraints together.
