Abstract:
The leakage detection structure of high-pressure urea equipment is the basic functional unit of the leakage detection system to monitor in real time whether the medium of the equipment leaks. The shell of high-pressure equipment usually adopts the structure of single-layer carbon steel or multi-layer wrapping structure with corrosion-resistant lining, Based on the different structure forms of pressure-bearing shell of equipment,this paper introduces in detail the structural differences of leakage detection grooves and holes in the leakage detection system of high pressure urea equipment and their respective characteristics of design and manufacturing, which can serve as design reference for the leakage detection structure of high-pressure urea equipment.
