Propane produces a lower flame temperature than acetylene (the maximum flame temperature in oxygen is compared with 3, 160 degrees 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.

Welding gas is a mixture of various hydrocarbons, principally, methylacetylene , propadiene and propane(mapp). It produces a relatively hot flame (2, 976c) with a high heat release in the primary flame (inner cone) (15, 445kj/m 3 ), less than for acetylene (18, 890kjm 3 ) but much higher than for propane (10, 433kjm 3 ). The secondary flame (outer cone) also gives off a high heat release, similar to propane and natural gas. The combination of a lower flame temperature, more distributed heat source and larger gas flows compared with acetylene results in a substantially slower pierce time.

Hfc-134a is internationally recognized as one of the main refrigerant working substances to substitute cfc-12. It does not contain chlorine atom, gives no bad effects against ozonosphere and has excellent safety performances, such as non-inflammability, non-explosive ability, non-toxicity, non-pungency, and non-corrosive ability. It is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself. As the substitute for cfc-12, it is often used in the refrigerating systems of auto air conditioners, commercial and industrial purposes, and as the vesicant, it is used to produce the heat-protective material made of rigid plastics, and also to prepare other blend refrigerants, such as r404a & r407c.
Hfc-143a can be used as a refrigerant to substitute r502. It does not contain the chlorine atom, give no bad effects against ozonosphere and has excellent safety performances, such as non-explosive ability, non-toxicity, non-pungency, and non-corrosive ability. And it is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself.
Refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back. The two main uses of refrigerants are refrigerators/freezers and air conditioners since it was discovered in the 1980s that the most widely used refrigerants were major causes of ozone depletion, a worldwide phase out of ozone-depleting refrigerants has been undertaken. The refrigerants we produced are "ozone-friendly" refrigerants. N/a
R410A is a colorless gas under ordinary temperature, and a colorless & transparent liquid under the pressure of itself, mixed by HFC-32 and HFC-125. And it is the substitute for R22, mainly used in the air conditioners and other refrigerating systems.
R407C is a colorless gas under ordinary temperature, and a colorless & transparent liquid under the pressure of itself, mixed by HFC-32, HFC-134a and HFC-125. R407C is the long-term substitute for R22, mainly used in the air conditioner and other non-centrifugal refrigerating systems.
R415b is an environment-friendly substitute for r12 in the refrigerators and freezers, etc. It has good environmental protection, no toxicity, non-combustibility, fast refrigerating speed and good energy-saving performance. Nearly no need to change parts, pipeline original refrigerator or icebox for original r12 and direct filling is enough.
Hcfc-22 is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself, non-toxic & inflammable with the excellent thermo-stability and chemical stability, unable to erode metals and it is a refrigerant for low temperature to 80 below. Used in reciprocating compressor, as refrigerant in industrial, commercial and household air-condition system; also used to produce insecticide and aerosol for spraying paint; to produce extinguishing agent 1211; as the basic material to produce a wide variety of fluorinated macromolecular compounds. 30lb/13.6kg; 50lb/22.7kg; 926l tank; 18-20mt isotank

R22 refrigerant is a chemical that keeps the air coming from your air conditioning system cool, so it's unquestionably incredibly important. Most air conditioning units older than 10 years utilize an AC refrigerant called R22 that's commonly identified as Freon*, and is noted by the EPA as HCFC-22.
Refrigerant R134a is a hydrofluorocarbon (HFC) that has zero potential to cause the depletion of the ozone layer and very little greenhouse effect. R134a is the nonflammable and non-explosive, has toxicity within limits and good chemical stability. It has somewhat high affinity for the moisture
