Abstract
A device for connecting cryogenic fluid containers includes a connection having screw-threaded connection portions and a flange having at least one pair of openings spaced by a predetermined distance. The device also includes a retaining strap of L shape with two wings cut out in U shape, the front wing also having a pair of openings spaced by the same distance as the openings of the flange. Rivets secure the strap and the flange to each other. The front wing also has a marking identifying the gas corresponding to the distance between openings.
Claims20
A safety device for cryogenic fluid piping connections, comprising:
- a central body portion having a traversing fluid flow passage, first and second screw-threaded ends and a flange portion between said first and second ends, said fluid flow passage extending from the first end to the second end, said flange portion having at least one pair of openings spaced apart by a predetermined distance (d1);
- and
- a retaining member having a front part formed with a pair of openings spaced by said predetermined distance (d1) for securing the retaining member to the flange portion, and a rear part arranged and adapted to coact in abutment with an element of said piping connections.

- a central body portion having a traversing fluid flow passage, first and second screw-threaded ends and a flange portion between said first and second ends, said flange portion having at least one pair of openings spaced apart by a predetermined distance (d1);
- and
- a retaining member having a front part formed with a pair of openings spaced by said predetermined distance (d1) for securing the retaining member to the flange portion, and a rear part arranged and adapted to coact in abutment with a valve.
A safety device for connecting cryogenic piping, comprising:
- a connection member having a central body between first and second threaded ends, said central body having a traversing fluid flow passage and a flange with at least one pair of spaced apart openings through said flange;
- and
- an L-shaped retaining member having a first leg with at least one pair of openings for securing said retaining member to said flange and a second leg for engaging a component of said piping,
- wherein a marking on said retaining member indicates that said at least one pair of spaced apart openings in said connection member and said at least one pair of openings in said retaining member are connectable.
