Flame Burners and Blow Torches
Soldering, welding, flame cutting and brazing are processes widely used in the building, manufacturing, road construction, refrigeration, plumbing, power, leather industries and more. Especially for copper where LPG , propane, butane, is used widely, the two most common methods of joining copper tube and fittings have been soldering and brazing using varying degree of heat. LPG’s heat capacity is an ideal fuel for soldering and brazing within the air conditioning, plumbing, refrigeration and hydraulics industries.
In the jewellery making, LPG soldering torch is one of the most important pieces of equipment. Nearly every ornamental piece requires joining metal together using heat. In this particular application, several variants of the LPG spectrum are used for different purposes in jewellery making. In addtion to jewellery making, LPG torches are frequently employed for soldering copper and water pipes. It can also be used for some low temperature welding applications, as well as for brazing dissimilar metals together.
In the construction industry, LPG flame burners and blow torches are used to weld steel for constructing residential and commercial buildings. It is also used to cast iron and weld steel during the construction of rail tracks. Some also mix acetylene and LPG for welding steel and iron cast. LPG is also used in cutting of most carbon steel because it cuts through across layers and jumps air gaps with ease, leaving no slag on the steel. It can tolerate a greater nozzle to workpiece distance which reduces the risk of molten metal splashing back onto the nozzle and causing a "backfire".
LPG is a clean-burning fuel that doesn't cause metal to oxidise as readily as acetylene. It is also cheaper to buy and setup. Furthermore, the working also environment remains free from polluting gases and thus is conducive for workmen.
