Pipe Hanger Rod and Flange Structure for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Clevis hangers are limited in their ability to facilitate easy installation in various situations and lack rigidity, particularly under vibrations and thermal expansion of pipes.
Innovation Solution
A pipe hanger design featuring a connecting rod with a bent end portion that extends upwardly for easy installation, incorporating threaded bores and an outwardly projecting flange for secure coupling, allowing for rotational stability and thermal expansion absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional Clevis hanger with straight connecting rod is used, then the structure is simple and easy to manufacture, but the installation is difficult in various situations and the structure lacks rigidity under vibrations
Solution Approach 1:
The connecting rod is designed with a bent end portion that can rotate relative to the shank, allowing the hanger to adapt to different installation orientations and pipe positions. This dynamic capability enables easy installation in various situations while maintaining structural integrity through the interlocking flange design that prevents excessive movement.
2Reliability
If a conventional Clevis hanger without interlocking features is used, then the structure is simpler, but the hanger cannot prevent accidental release under vibrations
Solution Approach 1:
The flange is designed with an asymmetric L-shaped configuration that creates a unique interlocking geometry between the flange and the bent end portion. This asymmetric design ensures that the components lock together in the correct orientation while preventing accidental release, even under vibrational loads, without requiring additional complex fastening mechanisms.
3Adaptability or versatility
If a conventional Clevis hanger with fixed connecting rod is used, then the structure is rigid, but it cannot accommodate thermal expansion of pipes
Solution Approach 1:
The rotatable joint between the bent end portion and the shank provides controlled movement capability that allows the hanger to accommodate thermal expansion and contraction of pipes. The interlocking flange design ensures that this movement is controlled and does not compromise the overall structural stability or allow accidental release.
4Adaptability or versatility
If the bent end portion hangs downward under gravity as in conventional designs, then the structure is simpler, but the installation versatility is reduced
Solution Approach 1:
The bent end portion is designed to be rotatable rather than fixed in a downward-hanging position. This allows the hanger to be installed in various orientations with the bent end portion pointing in different directions as needed, providing installation versatility while maintaining a relatively simple connecting rod configuration.

AI summary
Pipe hanger including an upper hanger part, a lower hanger part and a connecting rod, the upper hanger part being adapted to be mounted to a support member, wherein in a closed state of the pipe hanger depending arms of the upper hanger part and corresponding legs of the lower hanger part are coupled by the connecting rod which is passed through bores of both the upper hanger part and lower hanger part, the connecting rod defining a substantially horizontal rotational axis. The connecting rod is provided with a male thread, wherein at least one of the bores of the depending arms are threaded holes, wherein in the closed state the shank of the connecting rod is threaded through said at least one threaded hole. At least one of the legs of the lower part has an outwardly projecting flange formed as a bent end portion of said leg.
