3 Terms and definitions
The following terms and definitions apply to this document.
Steel gas pressure welding gaspressureweldingofreinforcingsteelbar
The use of oxyacetylene flame or oxygen gas oil gas flame, butt the two steel heating, so that it reached the thermoplastic state (solid) (1150 ℃ ~
1250 ° C), or in the molten state (above 1540 ° C), a pressure-welding method.
Reinforced air pressure welder gaspressurewelderofreinforcingsteelbar
By the multi-mouth ring tube heater, pressure device, welding fixture for the composition of bar welding machinery.
The flame produced by the mixed combustion of oxygen (O2) and acetylene (C2H2), the maximum temperature is 3150 ℃.
Oxygen liquefied petroleum gas flame oxy-liquefiedpetroleumgasflame
Combustion of liquefied petroleum gas and oxygen formed by the flame, the maximum temperature of 2200 ℃ ~ 2800 ℃.
Multi-mouth ring tube heater multiplenozzlesringcanalheater
Flame heater consisting of gas mixing chamber and heating coil. Gas mixing is mainly spray-type, but also pressure type.
