How can this expansion be compensated for

While Power Engineering students may not see a direct application of these principles, the following types of problems are part of their 2 nd and 1 st class curriculum.

The following diagram represent a typical restricted thermal expansion scenario, with compound bars:. Given that the expansion is restricted, each bar will be subject to compression which in turn generates compression stresses. The sum of the two corresponding yet imaginary compression deformations will be equal to the sum easily quantifiable unrestricted thermal expansions. Factoring in the cross-sectional areas of each bar leads to finding the stress developed in each material.

In the second scenario, a bar is pinned at both ends inside a tube of a different material. When heated up, one material would expand freely more than the other. The lower expansion material will be pulled outwards in tension by the second one that attempts to expand more. In turn, the material that would freely expand more it is pulled in compression by the material that expands less.

See the following figure for clarification. The latter are of maximum importance since they must allow the unimpeded and proper dilation of the pipes. In the following article, you can get more in-depth information about the proper installation of the fittings and the pressfitting pipes. For more information related to thermal expansion compensation in pressfitting systems, you can consult our Technical Office. Compressed air is an often indispensable resource in numerous industrial processes.

Using the stainless steel pressfitting system to create The publication of video tutorials on steel pressfitting systems continues.

After having learned to cut the pipe correctly, this Sustainable air conditioning through non-sustainable sources? Until a short time ago we would have immediately thought of district heating, The quality and good operating conditions of the pressing tools are of fundamental importance in order to create a The pressfitting system helps significantly to reduce the assembly time of plumbing systems.

Any type of fastener known to those skilled in the art can be used, such as but not limited to, screws, bolts, pins, dowels, etc.

In addition adhesives and other non hardware joining methods can be used effectively. The thermal expansion compensation system 40 can be constructed using three linear members 43 , 44 , 45 as shown in FIGS.

This three linear member embodiment results in a thicker overall structure because the three linear members cannot be co-planar. The first member 43 is positioned adjacent to the first component 41 with the higher CTE. The second member 44 is positioned across the first member 43 , at a 60 degree angle and the third member 45 is positioned across the second member 44 at a 60 degree angle. The second component 42 not shown in FIG. Holes 53 , 54 , 55 in one end of each compensation member 43 , 44 , 45 are used to attach it to the first component 41 and holes 63 , 64 , 65 in the other end of the compensation member 43 , 44 , 45 are used to attach it to the second component 42 not shown in FIG.

Longer pins 66 , 67 , 68 , shown in FIG. The first component 41 which is made from a material with a higher CTE is fastened to a second component 42 made from a material with a lower CTE by three expansion members 43 , 44 , 45 with an intermediate CTE. Without further elaboration, it is believed that one skilled in the art can use the preceding description to utilize the invention to its fullest extent.

Therefore the examples and embodiments disclosed herein are to be construed as merely illustrative and not a limitation of the scope. It will be obvious to those skilled in the art that many changes, such as types of materials, and member and component shapes, may be made to the details of the above described embodiments without departing from the underlying principles of the invention. The scope of the present invention should, therefore, be determined only by the following claims.

The system utilizes three compensation mounts made from a material with a coefficient of thermal expansion that is between that of the two materials being fastened together. This system allows for materials to be fastened together, and when placed in an environment with temperature fluctuations, the system experiences zero, minimal or insignificant amounts of thermal induced stress.
