  2. MAPP gas - Wikipedia

    en.wikipedia.org/wiki/MAPP_gas

    Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen. Although acetylene has a higher flame temperature (3160 °C, 5720 °F), MAPP has the advantage that it requires neither dilution nor special container fillers during ...

  3. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel. Other welding gases that develop comparable temperatures need special procedures for safe shipping and handling.

  4. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    Copper tubing conducts heat away much faster than a conventional hand-held soldering iron or gun can provide, so a propane torch is most commonly used to deliver the necessary power; for large tubing sizes and fittings a MAPP-fueled, acetylene-fueled, or propylene-fueled torch is used with atmospheric air as the oxidizer; MAPP/oxygen or ...

  5. Propane torch - Wikipedia

    en.wikipedia.org/wiki/Propane_torch

    Propane torches are frequently employed to solder copper water pipes. They can also be used for some low temperature welding applications, as well as for brazing dissimilar metals together. They can also be used for annealing, for heating metals up in order to bend them more easily, bending glass, and for doing flame tests. [5] [6]

  7. Lead burning - Wikipedia

    en.wikipedia.org/wiki/Lead_burning

    Wiping a lead joint is a soldering process, using plumber's solder (80% lead / 20% tin) and is carried out at low temperature, with a natural-draught propane blowtorch. Today, even wiped joints are rare and where an existing lead pipe must be connected to, a proprietary mechanical joint is more likely to be used.

  9. Copper tubing - Wikipedia

    en.wikipedia.org/wiki/Copper_tubing

    Solder fittings are smooth and easily slip onto the end of a tubing section. The joint is then heated using a torch, and the solder is melted into the connection. When the solder cools, it forms a very strong bond that can last for decades. Solder-connected rigid copper is the most popular choice for water supply lines in modern buildings.
