Abstract
A piping connection system and method to connect a double pipe system such as a double pipe heat changer to a housing, for example a housing of a manifold. In examples, the piping connection system and method may include a transition member configured to bond or connect to the double pipe system and to the housing. In examples, the piping connection system may include a baffle configured to redirect flow from the housing to the double pipe system through an opening and towards the transition member. In examples, the piping connection system and method may be used to manufacture a quench exchanger such as a primary quench exchanger.
Claims20
A pipe connection system comprising:
- a transition member configured to be bonded to an inner pipe of a double pipe system;
- a housing comprising an outer perimeter configured to be bonded to an outer pipe of the double pipe system and to the transition member;
- and
- a baffle defining an opening proximate the transition member and arranged to deflect flow towards the transition member and through the opening, wherein the opening provides fluid communication between the housing and a space between the outer pipe and the inner pipe of the double pipe system.
A quench exchanger comprising:
- a double pipe heat exchanger comprising an inner pipe and an outer pipe;
- a first transition member connected to an inner pipe of the double pipe heat exchanger;
- a first manifold connected to the double pipe heat exchanger and to the first transition member;
- and
- a first baffle defining a first opening proximate the first transition member, the first baffle arranged to deflect flow towards the first transition member and through the first opening, wherein the first opening provides fluid communication between the first manifold and a space between the outer pipe and the inner pipe of the double pipe heat exchanger.
A method of making a flow connection to a double pipe heat exchanger comprising:
- bonding via external welding a first transition member to a surface of a first outer portion of an inner pipe of the double pipe heat exchanger;
- and
- bonding a first manifold to the first transition member and to an outer surface of an outer pipe of the double pipe heat exchanger.
A method of making a primary quench exchanger comprising:
- providing a plurality of double pipe heat exchangers, each double pipe heat exchanger comprising an inner pipe located within an outer pipe;
- bonding via external welding a first transition member to a first portion of an outer surface of each inner pipe of each double pipe heat exchanger;
- and
- bonding a first manifold to the first transition member and to an outer surface of each outer pipe of the double pipe heat exchanger.
