Abstract

The invention discloses a pressure vessel pressure-tight test and airtight test examination method. The method comprises 1, test preparation, 2, a hydraulic pressure test under test standards of A, use of clean water and a stainless steel container for a hydraulic test, water chloride ion content less than or equal to 25mg / L in the hydraulic test and removal of water spots after the test, B, aiming at carbon steel, 16MnR and normalizing 15MnVR, a water temperature of greater than or equal to 5 DEG C, aiming at other low-alloy steel, a water temperature of greater than or equal to 15 DEG C and aiming at other types of steel, a water temperature set according to design standards, C, filling with water, air arrangement at the top point of a container and emptying at an air exhaust opening and D, test pressure set according to drawing technical requirements, 3, an air pressure test and 4, an airtight test. The method has a reasonable process and a low manufacturing cost.

Description

technical field [0001] The invention relates to a pressure-resistant test and an air-tightness test of a pressure vessel. Background technique [0002] In the existing pressure test and air tightness test of pressure vessels, there are unreasonable process arrangements and numerous processes, which require relatively high operator experience, resulting in high production costs. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a pressure-resistant test and an air-tightness test for a pressure vessel with reasonable process and low manufacturing cost. [0004] To achieve the above object, the present invention provides [0005] A pressure-proof test and an air-tightness test inspection of a pressure vessel, comprising the following steps: [0006] 1) Preparation for the test: [0007] 1.1) Inspection standard: [0008] 1.1.1) Carry out a comprehensive insp...
