Pipe Restraint And Method For Using The Same
View pageUS Patent:
59344237, Aug 10, 1999
Filed:
Jul 22, 1996
Appl. No.:
8/681077
Inventors:
Ralph M. Kallenbach - Elgin IL
Assignee:
Sargent & Lundy - Chicago IL
International Classification:
F16F 712
US Classification:
188374
Abstract:
A pipe restraint and methods for its use are disclosed. The pipe restraint includes a hollow cylindrical housing of varying diameter. A shaft having first and second wedges is received by the housing. The housing is attached to a fixed structural member, such as a wall and the shaft is attached to the pipe. Depending on the force being applied to the pipe, one of the wedges engages the housing at a point where the diameter changes. The housing's resistance to movement of the wedges varies between two points of differing diameter of the housing. In one embodiment a disc spring assembly is located at one end of the housing. In one method a gapped restraint is attached to a pipe and the size of the gap in the restraint is less than the anticipated movement of the pipe due to a static load.
Energy Damping Device
View pageUS Patent:
49554670, Sep 11, 1990
Filed:
Dec 21, 1988
Appl. No.:
7/289362
Inventors:
Ralph Kallenbach - Elgin IL
Assignee:
Fluor Corporation - Irvine CA
International Classification:
F16F 1300
F16F 700
B60T 712
F16F 700
B60T 712
US Classification:
188381
Abstract:
An energy damping device that includes a piston-cylinder assembly having a cylinder and a piston movable therein. A pre-loaded double acting spring, and a friction assembly, are enclosed fully within the cylinder, and engage the piston concentrically. The spring acts against the friction assembly for forcing it into frictional engagement with the inner surface of the cylinder. The friction assembly includes at least one wedge for engaging the interior surface of the cylinder. The friction assembly further includes a plurality of spaced-apart compression rings, that are interleaved with the wedges, for forcing them into radially outwardly directed frictional engagement with the interior surface of the cylinder.
Seismic Pipe Restraint And Method For Using The Same
View pageUS Patent:
55885110, Dec 31, 1996
Filed:
May 15, 1995
Appl. No.:
8/441138
Inventors:
Ralph M. Kallenbach - Elgin IL
Assignee:
Sargent & Lundy - Chicago IL
International Classification:
F16F 712
US Classification:
188374
Abstract:
A system for limiting the movement of a pipe due to a seismic event is disclosed, including an energy absorbing device for restraining the pipe in the event of the seismic event, and a clamp adapted be attached about the pipe at a point where the anticipated unrestrained movement due to a seismic event is greater than the anticipated thermal movement of the pipe. The energy absorbing device is connected at one of its ends to the clamp, and the opposite end of the energy absorbing device is adapted to be connected to a substantially immovable support structure or wall. The device includes a first elongated member having a hollow portion therein and a second member mounted within the hollow portion of the first member. One of the first and second members has its front end fixedly connected to the clamp, and the other one of the members has its rear end adapted to be connected fixedly to the support structure. The first member includes a first interference means and the second member includes a second interference device so that as the first and second members move longitudinally relative to one another, the first and second interference device engage one another forcibly and thereafter the first and second members continue relative movement for load and displacement limiting purposes until they come to rest.
