The role of raw material belt in engineering practice

In engineering practice, the concept of sealing or tightness is frequently used to assess the performance of sealed joints. The degree of tightness in a system or equipment can be evaluated based on the leakage rate. From a physical perspective, absolute tightness does not exist. Instead, tightness should be understood as a relative condition, much like other measurable physical properties. According to existing literature, the tightness of a connection is defined as: "Under specific operating conditions, the leakage rate of the connection is below a specified threshold; or, under a given leakage rate limit, the connection can withstand certain operational conditions. If these conditions are met, the connection is considered tight; otherwise, it is deemed not tight." In reality, the measured leakage rate is influenced by various factors, including the testing environment, the detection method used, and the skill level of the personnel conducting the test. As a result, different testers, methods, or leak detection devices may yield inconsistent results. To address this, the literature provides a more precise definition for determining the tightness of a system: "Under a specific operating condition, if the leakage rate, measured using a designated leak detection method with appropriate sensitivity, is lower than a predefined reference value, the system or equipment is considered tight. Otherwise, it is not." This standardized approach ensures consistency and reliability in evaluating the integrity of sealed systems. Proper calibration of testing equipment, adherence to established procedures, and trained personnel are all essential components of achieving accurate and repeatable results.
