Abstract
A valve assembly having a bolt with a through hole for a security wire includes at least one valve of the valve assembly mechanically coupled to a pipe or to a section of another component of the valve assembly by a coupling or by a pair of mating flanges. At least one hollow bolt is bolted through a closing bolt hole of the coupling or a joining bolt hole of the pair of mating flanges. The at least one hollow bolt accepts a safety wire run completely through the hollow bolt in a longitudinal direction of the hollow bolt and extending completely through the closing bolt hole of the coupling or the joining bolt hole of the pair of mating flanges.
Claims14
A valve assembly comprising:
- at least one valve of said valve assembly mechanically coupled to a pipe or to a section of another component of said valve assembly by a coupling or by a pair of mating flanges;
- at least one hollow bolt comprising an unobstructed through hole, said at least one hollow bolt bolted through a closing bolt hole of said coupling or a joining bolt hole of said pair of mating flanges, said at least one hollow bolt to slidingly accept a safety wire run completely through said at least one hollow bolt in a longitudinal direction of said hollow bolt and extending completely through said closing bolt hole of said coupling or said joining bolt hole of said pair of mating flanges, the safety wire to extend beyond both longitudinal ends of said at least one hollow bolt;
- and
- a non-taut safety wire passing freely through said unobstructed through hole.
A valve assembly comprising:
- at least one valve of said valve assembly mechanically coupled to a pipe or to a section of another component of said valve assembly by a coupling or by a pair of mating flanges;
- at least one hollow bolt comprising an unobstructed through hole, said at least one hollow bolt bolted through a closing bolt hole of said coupling or a joining bolt hole of said pair of mating flanges, said at least one hollow bolt to slidingly accept a safety wire inspection marking run completely through said at least one hollow bolt in a longitudinal direction of said hollow bolt and extending completely through said closing bolt hole of said coupling or said joining bolt hole of said pair of mating flanges, the safety wire inspection marking to extend beyond both longitudinal ends of said at least one hollow bolt;
