  2. Pipe Joining Methods The next few Slides we will go over the different ways, how plumbers join pipe and fittings together. In each Slide we will list the different plumbing systems and joining methods.

  3. Solder Line This is the process of joining pipe by melting a filler metal with a low melting point into a joint. When the filler metal cools it bonds the two pieces of metal together. In plumbing this technique is mostly done with copper piping. Soldering is used on all three plumbing systems Water Waste and Vent piping.

  4. Benefits of Solder Line The science behind soldering is very old and has literally stood the test of time. There is a learning curve but it isn’t steep by any stretch so it’s fairly easy to learn. The joints are fairly strong and water tight if done properly.

  5. Brazing Brazing is very similar to soldered joints in that a filler metal with a melting point lower than the metal being joined is used to fill a joint between two base metals. Brazing is done primarily on water piping and more specifically on water services or larger diameter piping. It is a much more forgiving technique. The joints end up being stronger than the filler metal because of the way it reacts to the metal being brazed and are significantly stronger than a soldered joint.

  6. Threaded Threaded pipe and fittings as they relate to galvanized water piping is a dying joining option. It will always be used for repairs or on specialized fittings, flange fittings but it is not a preferred installation. There are many drawbacks to using threaded fittings one of which is the fact that the galvanized pipe and fittings can be difficult to repair

  7. FUSE SEAL Fusion technology is used when the plastics being joined can’t be joined using cement. The basic procedure is as follows, a device/tool is used to heat the fitting and piping to a certain temperature melting a thin layer of the polypropylene plastic, the pipe is inserted into the fitting making sure the pipe hits home. After a certain time, usually around 15 to 20 seconds the pipe and fitting can no longer be manipulated and the fitting cures. The pipe and fittings actually fuse into one piece along the area of contact ensuring a positive seal.

  8. Benefits Fuse Seal 20% material savings versus copper. There is a learning curve with the preparation and joining process however it is far more forgiving than it’s copper counterpart. You will realize a labor savings once the technicians become proficient at the joining method. It is naturally acid resistant so neither hard water nor soft water has any affect.

  9. MECHANICAL JOINT A mechanical joint is any method joining piping or fittings by way of a coupling that uses compression of a rubber gasket to ensure a water tight seal. Two examples of mechanical joints are Flanged pipe and fittings Grooved pipe with couplings or fittings That have a rubber gasket which sits inside the groove and the rubber is compressed filling the groove and sealing the joint
