Abstract:
A temporary pipe damming composition comprising water, shredded paper, triethanolamine, Carbomer, and a preservative are mixed into a dough-like consistency. The damming composition is molded and inserted into a pipe to isolate any water or moisture from a working area. The plumber assembles the piping, securing the joints via a sweating process. The damming composition is dissolved by increasing the water pressure after completion and inspection of the plumbing work.

Description:
FIELD OF THE INVENTION 
     The present disclosure generally relates to a composition and method for aiding in sweating a piping joint. More particularly, the present disclosure relates to a semi solid, water soluble composition and the process of inserting the composition into an interior of a pipe to isolate moisture from a joint being sweated, then removing the composition via fluid pressure and dissolution. 
     BACKGROUND OF THE INVENTION 
     Pipe sweating is a trade term for soldering pipes together. This type of pipe sweating is performed with a propane torch. The copper pipes to be joined are heated at the juncture point, and then solder—a metal compound that is heated and used like glue between the two pipes—is applied. Pipe sweating can be a tricky venture for beginners, and it often takes a little while for a novice to get the feel of it. 
     Pipes cannot be soldered if water is in them. Water prevents the pipes from reaching a hot enough temperature to melt solder. One known means of ensuring water is isolated from the working area is to insert a piece of bread (without its crust) into the pipe holding back a gradual flow of water. The bread will dissolve when the water is turned back on. The problem with this is that the bread can become moldy, the bread takes an inconsistent amount of time to degrade, and the bread could cause temporary clogging. 
     Another known embodiment utilises a mechanical seal that is inserted into the plumbing to isolate any moisture from the area being brazed or soldered. This requires access to the device both before and after the sweating process. Since the device needs to be removed from the plumbing, the process requires at least one joint that is formed without using an isolation device. 
     Therefore, a water isolation composition that can be inserted into a piping configuration and dissolves when subjected to a water pressure/flow for use during a sweating process, is needed. 
     Several ingredients are known. 
     Ultrez 21 is a polymer that is a hydrophobically modified cross-linked acrylate copolymer and is designed to efficiently impart thickening, stabilising, and suspending properties designed for use in a variety of personal care applications. The polymer incorporates patented technology, which allows it to quickly and easily self-wet. Ultrez 21 is a trade name, generically referred to via its chemical reference of Acrylates/C10-30 Alkyl Acrylate Crosspolymer. 
     Triethanolamine, often abbreviated as TEA, is an organic chemical compound, which is both a tertiary amine and a tri-alcohol. A tri-alcohol is a molecule with three hydroxyl groups. Like other amines, Triethanolamine acts as a weak base due to the lone pair of electrons on the nitrogen atom. 
     Triethanolamine is commonly used as a pH balancer in cosmetic preparations in a variety of different products—ranging from skin lotion, eye gels, moisturizers, shampoos, shaving foams etc. Another common use of TEA is as a complexing agent for aluminium ions in aqueous solutions. This reaction is often used to mask such ions before performing what is called a complexometric titration with another chelating agent such as EDTA, which will form stable complexes with most metallic ions. 
     SUMMARY OF THE INVENTION 
     The present disclosure is generally directed to a water soluble composition for insertion into a piping configuration during a sweating process. The composition is inserted into a pipe creating a barrier for any water flow or moisture, thus allowing a plumber to adequately form a piping joint using a soldering or brazing process. The composition decomposes when subjected to an increased water pressure and subsequent flow. 
     In some embodiments, the temporary pipe damming composition may include:
         a volume of water;   a volume of shredded paper;   a volume of Carbomer;   a volume of Triethanolamine; and   a volume of Neolone.       

     In another aspect, the volume of water is preferably 85.1% of the total, having a range of +/−5%. It is desired that the water is de-ionized. 
     In still another aspect, the volume of shredded paper is preferably 8.8% of the total, having a range of +10%/−4%. It is desired that the shredded paper is siliconized shredded paper (fine grit). 
     In yet another aspect, the volume of Triethanolamine is preferably 3.0% of the total, having a range of +3%/−1%. 
     In a still further aspect, the volume of a Carbomer such as Acrylates/C10-30 Alkyl Acrylate Crosspolymer (Ultrez 21) is preferably 3.0% of the total, having a range of +3%/−1%. 
     In another aspect, the volume of a preservative (such as Neolone 950) is preferably 0.1% of the total, having a range of +0.3%/−0.1%. 
     In yet another aspect, a volume of a coloring agent (preferably FDA approved) can be added. 
     Continuing with another aspect, the composition is mixed in accordance with the following steps:
         a. Mix the shredded paper and water within a mixer until the solution is homogeneous.   b. Add Ultrez 21 and agitate until the composition turns into a dough-like semi-solid ball.   c. Add Triethanolamine and Neolone 950 and continue mixing. The Triethanolamine is used to neutralize the composition. The composition will separate from the wall of the mixing container.   d. In an optional step, a coloring agent can be added to the composition.       

     In a still further aspect, the composition is formed and inserted into a pipe. The plumber then forms the joint using common sweating practices. The water is turned on, increasing the water pressure in the piping. The water pressure separates the composition from the piping as well as dissolving the composition.

     An exemplary method of use of the temporary pipe damming composition  100  is presented in a sweating process flow diagram  200  of  FIG. 3  and respective exemplary illustrations of a plumbing joint configuration  300  presented in  FIGS. 4 and 5 . The user removes a temporary pipe damming composition mass  320  from the available mixed volume of temporary pipe damming composition  100  formed in accordance with the mixing flow diagram  150 . The plumber shapes the temporary pipe damming composition mass  320  into a ball or disc shape and inserts the temporary pipe damming composition mass  320  into a water source pipe  302 , referred to as a composition insertion step  202 . The plumber then assembles the various components  204 , such as slipping a coupling member  304  (in this case the coupling member  304  is a subcomponent of a valve assembly  310 ) over a prepared end of the water source pipe  302 . The plumber prepares the contacting surface of each component by abrading the surface and cleaning with a respective cleaning solution. The exemplary illustration inserts a distribution piping  306  into a discharging end of the coupling member  304 . The plumber can apply flux to each of the connecting surfaces during the assembly process. The plumber forms the joint via a sweating process (soldering, brazing, or similar) via a sweating step  206 . The joint is inspected  208  to ensure it is meets quality standards. Once the plumber determines that all of the assembly work is completed and inspected, the plumber increases the water pressure to the fluid  322 . The fluid  322 , when pressurized, dissolves the temporary pipe damming composition  100 , as referenced in a dissolving step  210 . 
     An advantage of the present invention is the ability to assemble a closed piping configuration, as the temporary pipe damming composition  100  is dissolved by the flow of water. The temporary pipe damming composition  100  dissolves in a predictable manner. The temporary pipe damming composition  100  maintains a long shelf life. 
     Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
