Precautions for the use of sight glass chemical equipment
The connection mode of sight glass line is mainly connected with a live flange, and there is a schematic diagram in SIO3587 and GH/T2435.
Sight glass is a good anti-corrosion material, it has the advantage of good corrosion resistance, even more than the stainless steel. In the production equipment of chloride and bromide, it is corrosion-resistant to stainless steel. Its disadvantage is that the mechanical strength is poor and fragile. In use, we should strengthen strengths and circumvent weaknesses, strengthen special protection, overcome its shortcomings, exert its advantages, and enable sight glass and chemical equipment to serve our chemical production.
Precautions for the use of sight glass chemical equipment
1, the installation of glass mirror chemical equipment, should be done after the installation of other equipment, to prevent the installation of other equipment to break the sight glass equipment. 2, after the installation of the equipment, the normal operation of the temperature and pressure to test the car to check the loopholes. After the cooling and depressurization, the fastening bolt should be tightened again.
3, when running, the cooling water should be opened first and the heat source should be opened. When closed, the heat source must be closed first, and then the water is cooled. 4, when the winter is closed, the cooling water should be released to prevent the glass lens from rising and cracking.
