Abstract
A bending restrictor assembly for use with a pipeline section has a sleeve affixed to the pipeline section, an outer collar slidably positioned relative to and over the sleeve, and an inner collar slidably positioned relative to an interior of the outer collar. The inner collar in spaced longitudinal relation to an end of the sleeve. The inner and outer collars are slidable relative to a bending of the pipeline section. A series of holes and keyways are formed in the inner and outer collars. Pins are inserted into corresponding holes and keyways so as to correspond to a limit of the bending radius of the pipeline section.
Claims19
A bending restrictor assembly for use with a pipeline section, the bending restrictor assembly comprising:
- a sleeve having an inner diameter greater than an outer diameter of the pipeline section;
- an outer collar slidably positioned relative to and over said sleeve;
- and
- an inner collar slidably positioned relative to an interior of said outer collar, said inner collar having an inner diameter greater than the outer diameter of the pipeline section, said inner collar positioned in spaced longitudinal relation to an end of the sleeve, said inner and outer collars being slidable relative to a bending of the pipeline section.
A bending restrictor assembly comprising:
- a pipeline section having an outer diameter and a length dimension;
- a sleeve affixed to said pipeline section, said sleeve having an inner diameter greater than said outer diameter of said pipeline section;
- an outer collar slidably positioned relative to and over said sleeve;
- and
- an inner collar slidably positioned relative to an interior of said outer collar, said inner collar positioned over and around said pipeline section, said inner collar having a inner diameter greater than the outer diameter of the pipeline section, said inner collar positioned in spaced longitudinal relation to an end of the sleeve, said inner and outer collars being slidable relative to a bending of the pipeline section.
A method of controlled bending of a pipeline section comprising:
- affixing a sleeve around an outer diameter of the pipeline section;
- slidably positioning a portion of an outer collar around an outer diameter of said sleeve;
- slidably positioning of a portion of an inner collar within an interior of another portion of said outer collar;
- and
- securing said portion of said outer collar to said sleeve and said another portion of said outer collar to said inner collar so as to limit a movement of said outer collar and inner collar relative to the control bending of the pipeline section so as to limit a radius of bends.
The method of claim 16, the steps of securing comprising:
- forming a hole into said sleeve;
- forming a keyway to a wall of said outer collar;
- and
- affixing a pin into said hole of said sleeve such that a portion of said pin extends into said keyway of said outer collar.
