Abstract:
A pipe coupling for joining together adjacent metal pipe segments, said pipe coupling comprising:(a) a hollow metal body having first and second open ends adapted for receiving respective proximal ends of the adjacent pipe segments, and first and second enlarged collars formed around said first and second open ends;(b) first and second annular solder grooves formed along an inside surface of respective first and second enlarged collars;(c) a solder alloy embedded in said first and second solder grooves, and adapted to flow between said body and the adjacent pipe segments when heated, such that upon subsequent cooling, the solder alloy joins the adjacent pipe segments and coupling together;(d) a soldering flux pre-applied to the inside surface of said body adjacent each of said first and second solder grooves for aiding the flow of said alloy between said body and the adjacent pipe segments; and(e) first and second removable protective covers positioned over respective first and second open ends of said body to prevent contamination of said soldering flux prior to application of the coupling to the adjacent pipe segments, and each of said protective covers including a pull tab for removing the cover from the end of the pipe segment.
