no. 1 example

[0011] A steel cylinder (100 liters) manufacturing plant that produces and stores volatile chemical reagent raw materials adopts the method of the present invention to carry out the leak detection test: before leaving the factory, each steel cylinder is filled with about 10 grams of F22 (a kind of saturated steam absolute pressure at normal temperature Freon substances close to 10 atmospheres), use the 20 grams per year file in the range of the halogen leak detector, and seal all the welds or other seals under the conditions that meet the above test environment requirements (for example: no F22 exists in the surrounding space) The joint part is tested with a halogen leak detector, and only steel cylinders with no F22 leakage can be shipped as qualified products.

no. 2 example

[0013] After the completion of the pipeline equipment system project in a chemical production line that produces harmful volatile substances, when performing the necessary leak test on it: first vacuumize the system project; then fill the system project with a certain amount of F22; then use Halogen leak detection instrument (the range is set according to the standard requirements related to the system engineering) to conduct leak detection tests on all welds or other sealing joints in the system engineering; finally, extract the previously filled F22 as much as possible and store it in a dedicated Store in cylinders for later use.

Abstract

The high precision leakage detecting test method for container and / or pipeline system is to fill halogen as medium into the tested container and / or pipeline system and to perform high precision test with halogen leakage instrument to the likely leakage position. The environment is tested with the halogen leakage instrument to ensure no halogen medium existing in the environment. The present invention has the features of being simple fast and reliable.

Description

Technical field: [0001] The invention relates to the technical problem of implementing high-precision leak detection for any container or (and) pipeline system. Background technique: [0002] At present, the conventional methods for implementing leak detection on containers and piping systems are: [0003] The most simple and rough method of smearing soapy water and foaming; the method of inflating and pressurizing the measured object in the water to detect leaks (similar to the common method of inflating and pressurizing the bicycle inner tube); Pressure method, that is, after inflating the measured container and piping system to a certain value (for example: 10 atmospheric pressure), observe whether the pressure drop after a certain continuous period of time (for example: 48 hours) is within the specified range. In the range. ------The test accuracy of this method has been improved a lot, but it is difficult to find the exact leak location, and the test time is too long....
