For the pipeline with pressure, the easiest problem in the production process is the leakage at the connection flange. Once leakage is found, do not tighten it under pressureBolt. There are some reasons for the leakage in the process of operation, such as gasket damage, pipeline under thermal stress, etc. At this time, just rely on twistingBoltIf the problem can not be solved, often screw the Bolt hard because the leakage has not been eliminated until the bolt is broken, and the high pressure gas in the pipe sprays out, causing injury accidents. There have been several factories that have broken bolts due to the screw bolts with pressure,FlangeLesson from the casualty accident of disc flying.
Therefore, it must be strictly abided by the forbidding of twisting with pressureBoltRules, do not hold fluke mentality in order to seize the time, hurry up with the task, violate the operating rules.

At present, there are two types of common condensing evaporators in domestic air separation units, plate fin condensing evaporator and tubular condensing evaporator. Tubular condensing evaporator is divided into three types: long tube, short tube and coil. The long tube and short tube are all in row. The tube is made of red copper and the tube sheet is made of brass. It is generally used in small and medium-sized air separation plants. Coil type is generally used for auxiliary condensing evaporator. Because there is no fixed liquid level in the coil, the heat transfer coefficient is small, so it has been gradually eliminated. The plate fin condenser evaporator is made of all aluminum structure, and the plate unit is arranged in vertical star shape. Its characteristics are compact structure, light weight, small volume and easy to manufacture. It is widely used in large and medium air separation plants. Due to the gradual enlargement of the air separation unit, the heat excha
