Support System for Process Piping and Method of Installation
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.
This is a continuation of application Ser. No. 13/343,749 filed Jan. 5, 2012, for Support System for Process Piping and Method of Installation, now U.S. Pat. No. ______.
TECHNICAL FIELDThe invention herein resides in the art of industrial piping systems, and more particularly, to such systems that are used for transporting fluid from one work station to another in a manufacturing process. Specifically, the invention relates to a support system for piping in a fluid manufacturing process, and particularly, the suspension or support apparatus, system installation, and the method of effecting the same. Most particularly, the invention relates to adjustable pipe hangers that may be secured to an overhead surface such as the ceiling, wall, floor or the like and which may be adjusted in situ to achieve a desired elevation or slope for the suspended pipe.
BACKGROUND ARTWith reference to
As shown in
Installation of the system 10 in the prior art was a costly and time consuming operation. It was generally a two step process, the first of which was the installation of a mock system of pipe support hangers, from which the lengths of the various hangers could be determined in order to achieve the desired elevations and slopes in the final installation. Accordingly, the work process was substantially doubled, the first half being the installation of the mock system and its associated hangers, often laid up with laser levels and the like. This mock installation would then be removed and replaced with a final installation where the hangers 16 had been cut to appropriate lengths and welded together for installation along the ceiling 14 and support members 24. Oftentimes, the installation of the mock system to take the necessary measurements for the in situ manufacture of the hangers 16 was the largest portion of time and effort consumed in the installation.
There is a need in the art of processed piping for a more cost effective system and method of installation than that presently being practiced. Indeed, there is a need in the art for an improved hanger which allows for adjustability in situ, obviating the need for a mock installation.
DISCLOSURE OF INVENTIONIn light of the foregoing, it is a first aspect of the invention to provide a support system for piping and method of installation which substantially eliminates the need for a temporary or mock layout of the piping system.
Another aspect of the invention is the provision of a support system for piping and method of installation which provides for in situ adaptability of support rods and hangers to effect proper positioning of the pipe.
Yet another aspect of the invention is the provision of a support system for piping and method of installation in which adjustable rods allow for both the initial installation of the pipe and fine tuning of its elevation and slope to ensure appropriate positioning and slopes throughout the piping system.
Still a further aspect of the invention is the provision of a support system for piping and method of installation wherein the support rods are threaded at each end and are of varying lengths and are adapted for receipt by threaded sleeves, one sleeve secured to a fixed structure such as a ceiling, and the other to a pipe receiving clamp.
Still a further aspect of the invention is the provision of a support system for piping and method of installation wherein the same hangers are used for initial installation and final installation, such that the adjustable rods, when adjusted to their final position, can be secured by weldments or the like, preventing any further adjustability or change.
Yet another aspect of the invention is the provision of a support system for piping and method of installation which is highly cost effective in manufacture and implementation, and is extremely reliable in use.
The foregoing and other aspects of the invention that will become apparent as the detailed description proceeds are achieved by a pipe hanger, comprising: a rod having first and second ends; a first sleeve adapted for connection to said first end of said rod; a second sleeve adapted for connection to said second end of said rod; a pipe receiver connected to said second sleeve; and wherein at least one of said first and second sleeves is adapted for adjustable connection to a respective one of said first and second ends, whereby an effective length of said rod between said first and second sleeves may be adjusted.
Other aspects of the invention that will become apparent as the detailed description proceeds are achieved by a piping system, comprising: a length of pipe extending along a distance; a plurality of hangers suspended from a support surface and receiving and maintaining said length of pipe at set elevations therealong, each of said plurality of hangers comprising: a rod of adjustable length operatively extending between said support surface and said pipe, and elevation of said pipe for each said hanger being set by adjustment of said adjustable length of said rod; and wherein adjustability of said length of said rod is terminable.
Yet further aspects of the invention that will become apparent herein are achieved by a method for installing a piping system, comprising: securedly attaching a plurality of pipe hangers from a support surface, each said hanger having a length; engaging said hangers with a pipe; adjusting an effective length of each of said plurality of hangers to set a desired elevation of said pipe at each said hanger; and fixing said length of each of said plurality of hangers when said elevations are set.
For a complete understanding of the various aspects of the invention, reference should be made to the following detailed description and accompanying drawings wherein:
The present invention contemplates the use of hangers employing adjustable threaded rods of varying lengths to both temporarily set the pipe and then permanently maintain it. In accordance with the use of the adjustable hangers of the instant invention, the layout of the installation and the final assembly are substantially joined together in a single step, reducing the time, materials, and incident costs for such installations.
With continued reference to the drawings and particularly
A pipe clamp or receiver 56 is attached to an end of the sleeve 52 by appropriate means such as welding, or the like. This attachment is typically made during the manufacturing process, such that the combination of the sleeve 52 and attached pipe clamp 56 comprise a single unit at the point of installation. The pipe clamp 56 is provided with a hinge 58 allowing it to open such that it can receive a pipe of appropriate diameter, in standard fashion. The clamp may then be closed upon the pipe and sealed closed as by any appropriate fastener including a weldment, nut and bolt, clip, or the like at the securing flange 60.
It will be appreciated that the adjustable hanger rod assemblies 40 will necessarily be of varying lengths, to accommodate any of the wide range of installations and variations in an associated overhead support system. The threads 44, 46 and mating threads 50, 54 allow for approximately 2 inches of adjustability, according to a preferred embodiment of the invention. Accordingly, it is contemplated that the rods 42 will be provided in lengths of 2 inch increments to accommodate most conceivable installations. It is, of course, most desired that at least approximately 0.5 inch of bite be present at the interengagement of each of the associated ends 44, 46 and sleeves 48, 52. Accordingly, marks such as score lines, painted lines, or the like 62, 64 are provided in association with respective ends 46, 44 and are so positioned that the exposure of the lines 62, 64 out of the associated sleeves 50, 52 indicates that no further adjustment is available with that rod and a longer rod (typically the next longer rod) should be employed. Of course, if the rod 42 bottoms out in the sleeves 48, 52, the next shorter rod should likely be tried.
In use, the rod 42 and associated threaded sleeves 48, 52 operate as a turnbuckle, such that rotation of the rod 42 in one direction increases the effective length of the rod, while its rotation in the opposite direction shortens it. The effect is that of lowering or raising the associated pipe clamp 56 and the secured pipe 12 when employed in the installation of
An appreciation of the installation of a piping system employing the adjustable hanger rod assemblies 40 of the instant invention may be obtained with reference to
Thus it can be seen that the various aspects of the invention have been attained by the structures and methods presented and described above. While in accordance with the patent statutes, only the best mode and preferred embodiment of the invention has been presented and described in detail, the invention is not limited thereto or thereby. Accordingly, for an appreciation of the true scope of the invention, reference should be made to the following claims.
