Sealability Testing: Concepts, Methods and Equipment Selection Guide

This article provides a comprehensive analysis of seal testing, covering related concepts, common methods and equipment selection. Sealability testing is crucial for many products to prevent gas or liquid leakage and to ensure normal operation and service life of the products. The paper introduces the concepts of sealing and leakage, describes the testing methods such as water immersion method and pressure decay method, and recommends equipment such as airtightness tester and true water tester.

Quick question and answer: What are the two types of equipment that are resistant to vandalism and whether or not the product leaks the working medium, respectively?

The article introduces two methods for testing the safety and reliability of industrial equipment: strength test and hermeticity test. The strength test uses a bursting tester to assess the equipment's resistance to damage and pressure-bearing performance; the hermeticity test uses a differential pressure hermeticity tester, which is highly accurate and fast, and can effectively assess the equipment's hermeticity performance. The article also mentions the customized solutions and successful cases of Precision Engineering's airtightness team, demonstrating its technical advantages and application achievements in the industry.

Popularization: product sealing leakage test rating standards and methods for details

This paper describes the rating criteria and methods for product leakage tests for sealing. Leakage is the migration process of gas molecules driven by differential pressure, and the leakage rate is the measurement index. Test rating needs to consider the leakage medium, leakage rate, test pressure and time and other factors. Commonly used methods include immersion method, pressure decay method, differential pressure comparison method and tracer gas method.
