Copper Welding-Brazing Pipe
The use of copper brazing is for when greater joints strength is needed or for systems that operate at 350 Degrees or higher.Brazing is a joint made at temperatures greater than 1,000° F. In many ways, Heat is approximately 840° F and the brazing rods used in plumbing; medical gas and refrigeration are all greater than 1,000° F.
Both oxygen-bearing and oxygen-free copper can be brazed to produce a joint with satisfactory properties. The full strength of an annealed copper brazed joint will be developed with a lap joint. Butt, lap, and scarf joints are used in brazing operations, whether the joint members are flat, round, tubular, or of irregular cross sections.Clearances to permit the penetration of the filler metal, except in large diameter pipe joints, should not be more than 0.002 to 0.003 in. (0.051 to 0.076 mm).
When looking for a stronger joint, brazing is one of the options. In addition to medical gas and refrigeration tubing, brazing is common in water piping and fuel gas piping, to name a few systems:-
Typical Uses Include:-
Water Supplies, HVAC-Heating and ventilation and air condition work, Fuel and gas distribution systems And Fire Protection.
