压力容器水压试验工艺守则(国外英文资料)Rules for hydraulic test procedure1, scope of applicationThis code specifies the technical requirements and operational specifications of the total and compression components of the steel pressure vessel in our company.2, the generalThe pressure test of the pressure vessel under pressure vessel shall be carried out after the non-destructive testing and the relevant inspection project are qualified. The compression elements and parts that need heat treatment should be treated after heat treatment.The pressure test, the test pressure press the tableNote: the pressure of pressure vessel of steel pressure vessel is the same as that of 1.25p and P + 0.1.The pressure vessel (considering the stability design) of the pressure vessel that determines the thickness of the wall is not determined by internal pressure calculation.(3), the design temperature, wall temperature is greater than or equal to 200 ℃ steel pressure vessel, pressure test pressure P T press type calculation:P T = PT [delta] / [delta] T = etaType: P - pressure vessel design pressure, MPaP T - pressure test under design temperature, MPaEta - pressure coefficient of pressure test[delta], [delta] T is the pressure of the material under the temperature of the test, and the MPa.Before 2.3, pressure test, pressure vessel of the connection parts of strong bolt will complete assembly, tighten properly, use two same range and the calibration of pressure gauge, installed in the test device for inspection of parts.The pressure gauge shall comply with the following provisions:2.3.1, the pressure gauge chosen must be adapted to the medium used.The pressure gauge of 2.3.2 and low pressure vessel should not be lower than 2.5, and the pressure gauge should be no less than 1.5.The dial scale of the pressure gauge is 1.0 to 3.0 times the maximum working pressure, preferably two times, and the dial diameter should not be less than 100mm.In the hydraulic test, the average membrane pressure of the pressure ve
