Gas Ptfe Tape Use
As we all know, the raw material belt is used to seal the pipe joint to make the pipe seal better. If the seal is not good, leakage will occur. At present, leakage is a common phenomenon in nature. The leakage of tap water and gas in daily life often brings inconvenience or even harm to people. In industry, such as pressure vessels, pipelines, reactors, valves, hydraulic pressure, and transportation vehicles, if it is light, it will cause a large waste of energy and raw materials, equipment will not work properly, and if it is heavy, equipment will be scrapped, the entire factory or system will be paralyzed, casualties and serious environmental pollution. Therefore, people try every means to prevent and eliminate leakage in production practice. Sealing refers to the phenomenon that there is no leakage at the joint of machinery and equipment. Parts that can play a sealing role are called seals. More complex sealing connections are called sealing systems or sealing devices. Common sealing equipment includes raw material tape, sealant, adhesive, etc. In engineering practice, the concept of sealing or tightness is commonly used to evaluate the effectiveness of sealed connections. The tightness of the system and equipment can be determined by the leakage rate. Physically speaking, there is no absolute tight piece. The so-called tightness should be like other physical quantities. Can be measured quantitatively. The document defines the tightness of the connection as: "Under certain operating conditions, the leakage rate of the connection is lower than the leakage rate of a specified index; or under the specified leakage rate index, the connection can withstand specific operating conditions. The connection satisfying the above conditions is tight, otherwise it is considered not tight ". In fact, the leakage rate of the connection is closely related to the average leak detection condition, leak detection method, leak detection personnel, etc. The test results obtained by different testers or using different leak detection methods and different leakage devices are often inconsistent. Therefore, the literature defines the system and the tight phase that is not prepared: "under a specific operating condition, the leakage rate measured by the specified leak detection method with corresponding test resolution is lower than the leakage rate of a specified index. Systems and equipment that meet the above conditions are tight, and vice versa ".
