Difference between press fittings and solder fittings

With press tecnique gaskets can be fitted without welding, so there is no need to use gas pumps or containers, completely eliminating any risk of fire.

The integrity of the pipelines insulation is safeguarded by the absence of heat sources.

Advantages

• Gaskets can be fitted without welding, eliminating the risk of fire in more hazardous situations (working in older buildings, furnished rooms, etc.)
• No need for dangerous gas pumps or containers, completely eliminating the need to make the connections required by law
• Elimination of all welding materials, with inevitable cost benefits
• Junctions free from burning or rings with an excellent immediate visual impact
• Integrity of pipe insulation thanks to the absence of heat sources

Brazing consists in the junction between two metal pieces (for example a pipe and a fitting) using a brazing alloy, which liquefies at a lower temperature than the two other metals which will be united.

After its fusion, the alloy penetrates by capillarity in the gap between the two pieces of metal.

Once solidified, it will be a unique piece with the two metals.

There are two types of brazing. The type depends on the fusion temperature of the alloy:

• Soft brazing: less than 450° C (bigger mechanical resistance)
• Hard brazing: more than 450° C

It is evident that brazing takes longer than pressing and it entails more risks because of the use of heat sources.
