Abstract
In a fluid material handling system, a pipe bend is reinforced with exterior tiles 6, which may be ceramic. The pipe bend may further include a chamber 5 in which fluent material is deflected. Also disclosed is a corresponding method of making the fluid material handling system featuring the reinforced pipe bend. The pipe bend with reinforcement tiles may subsequently be further coated in a resistance material. The pipe bend may provide reinforcement against leakage, for fluid material handling systems carrying abrasive material.
Description
CERAMIC-BACKED ELBOW
CROSS-REFERENCE TO RELATED APPLiCATION
100011 This application claims priority in U.S. Provisional Patent Application No. 61/983,858, filed April 24, 2014, which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
100021 The present invention relates generally to a ceramic-backed elbow, and more specifically to wear-resistant pipe elbow featuring a ceramic extension for providing wear-resistance while effecting short radius turns in fluent transport systems.
2. Description of the Related Art
100031 Existing wear-resistant elbows are made of typical materials which eventually wear over time. Existing "smart elbows," such as those taught by U.S. Patent No. 4,387,914 to Paulson et al. and assigned to HammerTek Corporation of Landisville, PA suffer from this issue.
BRfEF SUMMARY OF THE INVENTION
10004] According to an aspect of the present invention, there is provided a ceramic-backed elbow featuring an extended chamber which alters the flow of fluent through the elbow section. This chamber is lined with a ceramic material and ceramic tiles to increase the durability and wear-resistance of the elbow. The remainder of the elbow is similarly coated with a ceramic mixture for similar wear-resistance, [0005] Alternatively, the entire structure may be covered with ceramic tiles.
[0006] Alternatively, the tiles can be applied prior to a coating being placed over the entirety of the elbow, except for the open connecting ends of the elbow. This can be done by placing the elbow into a coating pan arid covering the elbow with the abrasive-resistant material.
10007] Embodiments of the present invention seek to provide a ceramic-backed elbow, and preferably a short radius elbow, with the benefits of ceramic tile and ceramic mixture components to increase the durability and wear-resistance of the pipe elbow.
10008] Heretofore there has not been available a ceramic-backed elbow with the advantages and features of the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
100091 EnThodiments of the present invention will now be described, by way of example only, in which: 100101 Fig. lisa side sectional view of an embodiment of the present invention.
10011] Fig. 2 is a side sectional view of an alternative embodiment of the present invention, 100121 Fig. 3 is a side sectional view of yet another alternative embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
I, Introduction and Environment
100131 As required, detailed aspects of the present invention are disclosed herein, however, it is to be understood that the disclosed aspects are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art how to variously employ the present invention in virtually any appropriately detailed structure.
100141 Certain terminology will be used in the following description for convenience in reference only and will not be limiting. For example, up, down, front, back, right and left refer to the invention as orientated in the view being referred to. The words, "inwardly" and "outwardly" refer to directions toward and away from, respectively, the geometric center of the aspect being described and designated parts thereof, Forwardly and rearwardly are generally in reference to the direction of travel, if appropriate. Said terminology will include the words specifically mentioned, derivatives thereof and words of similar meaning.
II, Preferred Embodiment Ceramic-Backed Elbow 2 100151 A preferred embodiment features a low radius elbow 4 including an extension with a cavity 5, sometimes referred to as a deflection zone, similar to the Smart Elbow ® produced by HammerTek Corporation of Landisville, PA. The extension is surrounded by several ceramic tiles 6 which increase the life of the elbow by providing wear-resistance, The remainder of the elbow may be coated with a ceramic mixture 8 that similarly increases the life of the elbow. Due to the majority of wear occurring within the cavity 5, the ceramic tiles 6 are only necessarily placed in proximity to the cavity. However, they could be placed throughout the elbow if desired, 100161 As material flows through the elbow, the elbow tends to wear out, especially in the deflection zone cavity S. When using highly abrasive material, like powders, the wearing out of the elbow 4 occurs even faster. The ceramic files 6 are highly resistant to abrasive wear and extend the life of the elbow for much longer than a non-protected elbow, III. Alternative Embodiment Coated Elbow 22 100171 Fig. 2 shows an elbow 4 with a ceramic coating 8, or other abrasive resistant coating such as a ceramic mixture, a cement mixture, or a urethane mixture, is applied to all surfaces of the elbow 4, except for the open ends of the elbow where the elbow connects to other pipe sections. This ceramic coating is applied similarly to the related patent application No. 14/694,168, assigned to Progressive Products, Inc. of Pittsburgh, Kansas, which is incorporated in its entirety herein by reference. The method of coating a pipe section includes placing the elbow into a coating pan while leaving the ends of the elbow exposed, coating the elbow with the abrasive-resistant material, and allowing the material to harden. A thin metal skin can be placed over the abrasive-resistant material to provide additional abrasive resistance and to allow for easy patching to further extend the life of the elbow.
IV. Alternative Embodiment Coated Ceramic-Backed Elbow 32 100181 Fig. 3 shows an elbow 4 with a ceramic coatingS and several ceramic tiles, which combines the two embodiments disclosed above. This provides the maximum level of wear-resistant protection to the elbow and extends the life of the elbow for several times the length of an elbow alone.
100191 Any other pipe section, including straight pipe sections, could be fitted with ceramic tiles 6 and/or abrasive-resistant coatings 8; however, the elbow 4 with a deflection zone cavity 5 presents the best example of a pipe section requiring high levels of abrasion resistance to prevent constant replacement of pipe section parts, which can cause a shutdown in production.
100201 It is to be understood that while certain embodiment and/or aspects of the invention have been shown and described, the invention is not limited thereto and encompasses various other embodiments and aspects.
100211 The disclosures in United States patent application nos. 61/983,858 and 14/694,531, from which this application claims priority, and in the abstract accompanying this application are incorporated herein by reference.
