MAPP GAS can be used in combination
with oxygen for
heating, soldering, brazing and
even welding due
to its high flame temperature of
(3600 °F) in oxygen. For small-scale welding with Mapp Gas this is not a
serious problem,. Mapp Gas is also used in combustion with air for brazing and
soldering, where it has a slight advantage over competing propane fuel
due to its higher combustion temperature of (3,600 °F) in air.

CQ-type engineering plastic magnetic pump installation and precautions
CQ hydraulic pump is a plastic pump made of corrosion-resistant polypropylene material, especially suitable for easy to leak, flammable, explosive liquid pumping, then the pump installation and use, you need Pay attention to what? With this question, then we introduce the CQ type engineering plastic magnetic pump installation and use precautions. CQ-type engineering plastic magnetic pump installation and use precautions 1, magnetic pump should be installed horizontally, should not be erected, plastic pump body can not withstand the weight of the pipeline, for special requirements of the vertical installation of the occasion, the motor must be upward. 2, when pumping liquid level higher than the axis of the pump, open the suction pipe valve before starting can, if the suction level below the pump axis, the pipeline should be equipped with the end of the valve. 3, the pump should be checked before use, the motor blades to rotate flexible, no stuck without abnormal sound, the fasteners to be fastened. 4, check whether the motor rotation direction and magnetic pump steering mark the same. 5, the motor starts, slowly open the discharge valve, to be pump into the normal working condition, and then adjust the discharge valve to the desired opening. 6, the pump stopped working, you should close the discharge valve, and then close the suction pipe valve.
