difference between butane propane gas

Product Name : Propane gas

Product Category: Welding & Brazing gas

propane is a three-carbon alkane, normally a gas, but compressible to a liquid that is transportable. It is derived from other petroleum 

products during oil.

Propane produces a lower flame temperature than acetylene (the maximum flame temperature in oxygen is 2,828C 

compared with 3,160C for acetylene). Consequently, piercing is much slower but as the burning and slag formation 

are effected by the oxygen jet, cutting speeds are about the same as for acetylene.
