Adjustable Threaded Rod Piping Hanger for In-Situ Elevation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial piping systems require a costly and time-consuming two-step installation process, involving a temporary mock layout and subsequent welding of hangers to achieve desired elevations and slopes, which can be inefficient and labor-intensive.
Innovation Solution
The use of adjustable threaded rods with varying lengths, which can be secured to fixed structures and pipes, allowing for in-situ adjustment and final securement through welding, eliminating the need for a mock installation and enabling precise elevation and slope adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional welded hanger system is used, then the piping system achieves stable support, but the installation process becomes time-consuming and costly due to requiring a mock layout followed by final installation
Solution Approach 1:
The hanger rod incorporates a threaded adjustment mechanism that allows the effective length to be dynamically changed during installation. This enables the rod to be adjusted in-situ to achieve precise elevations and slopes without requiring a preliminary mock layout, thereby reducing installation time while maintaining support stability.
Solution Approach 2:
The invention changes the parameter of rod length from fixed (in traditional welded hangers) to adjustable via threaded connection. This parameter change allows the hanger to adapt to different installation requirements directly on-site, eliminating the need for a two-step installation process and reducing overall installation time.
2Reliability
If a traditional welded hanger system is used, then the piping system achieves stable support, but the installation cost increases due to the two-step installation process
Solution Approach 1:
The adjustable threaded rod allows for direct installation without mock layout, reducing labor costs and material waste associated with removing and replacing hangers. The same hanger unit serves both installation and final configuration purposes, thereby reducing overall installation cost while maintaining support stability.
3Ease of manufacture
If fixed-length rods are used in hangers, then the manufacturing process is simple, but the ability to adjust elevation and slope in-situ is lost
Solution Approach 1:
The rod is segmented into multiple sections with threaded connections, allowing the effective length to be adjusted by changing the overlap or engagement of these segments. This segmentation enables in-situ adjustment of elevation and slope while keeping the manufacturing of individual segments relatively simple.
Solution Approach 2:
The threaded connection mechanism transforms the rod from a fixed-length component to an adjustable-length component. This dynamic feature allows the rod to be adjusted during installation to achieve precise elevations and slopes, thereby providing in-situ adaptability while maintaining manufacturing simplicity.
4Adaptability or versatility
If adjustable threaded rods are used, then in-situ adjustment of elevation and slope is enabled, but the device complexity increases
Solution Approach 1:
The rod is divided into segments with threaded connections, which adds adjustability but keeps each segment relatively simple in design. The segmentation allows for straightforward manufacturing of individual parts while enabling complex adjustment capabilities when assembled.

AI summary
A support system for process piping and method of installation are presented. An adjustable hanger rod assembly includes a rod with oppositely oriented external threads at opposite ends thereof. These threads are adapted to mate with internal threads in respectively associated sleeves. One of the sleeves is fixed to a support system, while the other sleeve is fixedly secured to a pipe clamp. The oppositely oriented threading of the rod allows the rod to operate as a turnbuckle, such that rotation of the rod adjusts the elevation of the pipe clamp and an associated pipe retained thereby. Once a desired adjustment has been achieved, the rod and associated pipe clamp may be locked into position by tack or spot welding of the rod to the associated sleeves.
