What is the max psi for PROPYLENE?

It's Safer Than Acetylene Gas

Propylene gas has a much higher operating pressure limit (133 psi) compared to Acetylene (15 psi), and is therefore a much safer and more time-efficient fuel gas to operate with.

Can PROPYLENE be used for welding?

Brazing techniques with PROPYLENE are the same as for acetylene. The safe high energy fuel for cutting, heating, brazing & welding. Converting to PROPYLENE acetylene gauges, torches and welding tips usually work well with PROPYLENE. Very often, the same size tip can be used for welding with acetylene or PROPYLENE.

What burns hotter propane or PROPYLENE?

Propylene combines the qualities of an acetylene flame with the secondary heating capacity of propane. This fuel gas burns hotter than propane. When compared with acetylene, propylene offers greater safety as it can be utilized up to full tank pressure.

Is propylene an alkene?

It is named using the same stem as the alkane having the same number of carbon atoms but ends in -ene to identify it as an alkene. Thus the compound CH2=CHCH3 is propene.
