What tests are required for ethylene spheres? According to TSG R7001-2013 \"Rules for Periodic Inspection of Pressure Vessels\", there are a total of 18 items for the periodic inspection of fixed pressure vessels: review of vessel documentation, visual inspection, inspection of safety accessories, measurement of wall thickness, strength verification, radiographic testing, ultrasonic testing, Time-of-Flight Diffraction (TOFD) ultrasonic testing, magnetic particle testing, penetrant testing, acoustic emission testing, analysis of material composition, hardness testing, metallographic analysis, pressure test, airtightness test, ammonia leak detection test, and helium-halogen leak detection test. During periodic inspections, the inspection items to be carried out are selected based on the condition of the pressure vessel.
The items included in the regular inspection of ethylene spherical tanks are: review of pressure vessel documentation, visual inspection, inspection of safety accessories, measurement of wall thickness, strength verification, radiographic testing, ultrasonic testing, Time-of-Flight Diffraction (TOFD) ultrasonic testing, magnetic particle testing, penetrant testing, acoustic emission testing, material composition analysis, hardness testing, metallographic analysis, pressure testing, airtightness testing, ammonia leak detection testing, and helium-halogen leak detection testing. Select appropriate inspection items based on the actual conditions of the ethylene sphere tank. .
