Abstract
The device for obviating or making difficult the rupturing of a pipeline having a risk zone includes, in one embodiment, a plurality of tension bars which bridge the risk zone and tensioning bands which extend peripherally about the tension bars to press the bars against the pipeline at the respective ends. In other embodiments, tension pins are disposed at the ends in arcuate segments which circumferentially surround the pipeline on opposite sides of a rupture zone while tensioning bands in the form of chains surround the arcuate segments in order to press the segments against the pipeline.
Claims19
In combination with a pipeline having a rupture-risk zone and peripheral grooves in a peripheral surface, a device for preventing rupture of said pipeline in said risk zone, said device including
- a plurality of tension bars secured to and distributed uniformly about said peripheral surface of said pipeline on opposite sides of said risk zone, each said tension bar having a tooth system at least on one end in engagement with said grooves;
- and
- at least one tensioning band extending peripherally about said pipeline and said tension bars to press said tension bars against said pipeline.
In combination with a pipeline having a rupture-risk zone and at least one recess in a peripheral surface, a device for preventing rupturing of said pipeline in said risk zone, said device including
- a plurality of tension bars distributed uniformly about and secured to said peripheral surface of said pipeline on opposite sides of said risk zone, each said tension bar having a bore in radial alignment with said recess;
- at least one tensioning band extending peripherally about said pipeline and said tension bars to press said tension bars against said pipeline;
- and
- a pin in each bore and said recess.
In combination with a pipeline having a rupture-risk zone, a device for preventing rupturing of said pipeline in said risk zone, said device including
- a plurality of tension bars distributed about and secured to a peripheral surface of said pipeline on opposite sides of said risk zone;
- a plurality of annular segments peripherally disposed about said pipeline on opposite sides of said risk zone, each said segment receiving one end of at least one respective tension bar therein;
- and
- at least one tensioning band extending peripherally about said pipeline and said tension bars to press said tension bars against said pipeline.
The combination with a pipeline having a rupture-risk zone, a device for preventing rupturing of said pipeline in said risk zone, said device including
- a plurality of annular segments disposed about said pipeline on at least one side of said zone;
- a plurality of tension bars distributed about said pipeline and extending through said annular segments across said zone;
- a chain disposed about said annular segments for pressing said segments against said pipeline;
- and
- means for anchoring said tension bars to said pipeline on an opposite side of said zone.
