Metal welding - Import export

MAPP Gas & Hard Torch SetThis series of portable welding gun is suitable for red welding joints Between various non-ferrous metals, and for melting welding between similar non-ferrous metals with low melting point (such as aluminum + aluminum, brass + brass jcintsi; for rod welding between ferrous metals, and welding joints composed of ferrous metals and non-ferrous metals, selecting appropriate rod materials and flux can also obtain good rod welding joints. Commodity characteristics: 1. Safe, convenient, professional and concise. 2.The combustion temperature of.HT MAPP GAS can reach above 1250 C without oxygen and combustion. 3.HT MAPP CAS is a patent formula gas for mixed gas. 4. Diameter 75mm. high 267mm for single hand welding, easy to carry. S.Scientific mixing ratio, good flame characteristics, so as to ensure the welding effect and shorten the working time. 6. Under normal working conditions, it can achieve continuous combustion time of 2 hours and 30 minutes.

MAPP gas is a fuel gas based on a stabilized mixture of methylacetytene (propyne) and propadiene. The name comes from the original chemical composition: methylacetylere-propadienepropane. A typical composition for MAPP gas might oe: methylacetylene Ipropyne) 48%, propadiere 23%, propane 27%. MAPP gas is widely regarded as a safer 3nd easier-to-use substitute for acetylene.UseMAPP gas provides a flame that is hot enough for brazing and metalling, but the gas is much more stable and safer to use than acetylene. Burning propane does not produce enough heat to weld stronger metals, but MAPP gas burrs aoout 2,000 degrees Fahrenheit hotter than propane.
