Insurance claims for air separation equipment

A low pressure nitrogen expander is added to the process design. The pressure nitrogen from the pressure tower and high pressure expander is expanded into low pressure nitrogen, which is combined with the nitrogen coming from the low pressure tower and fed into the charge gas compressor. This is specially set up for rapid oxygen load changes. The oxygen product flow rate during normal operation corresponds to the amount of oxygen contained in the amount of air entering the air separation unit. T...

Under the conditions of certain welding methods, welding materials, welding specification parameters and welding structure, the difficulty of obtaining high-quality welded joints is called steel weldability. Therefore, the weldability should be evaluated from two aspects of manufacturing and application. The weldability of process mainly refers to the possibility of various cracks in welded joints, which reflects the difficulty of manufacturing. Weldability of using mainly refers to the mechanical properties and special properties of heat resistance, corrosion resistance, low temperature resistance and fatigue resistance of welded joints, which reflects the reliability of use.
