Equipment Configuration：orifice plate flowmeter
The reasons for orifice plate flowmeter with metal wound gasket include: good sealing to ensure accurate measurement, temperature and pressure resistance to adapt to harsh working conditions, corrosion resistance to extend the service life, compensation for unevenness to ensure tightness, reduce maintenance and lower costs.
Project Overview
The orifice plate flowmeter needs to be equipped with a metal spiral gasket mainly for the following reasons:
1. Sealing performance: The metal spiral gasket has good sealing performance and can ensure that the orifice plate is in contact with the pipe or pipe. No leakage occurs at the connection between flanges. This is critical for accurate measurement by the flow meter, as any leakage will affect the flow of fluid through the orifice plate, resulting in inaccurate measurement results.
2. Temperature and pressure resistance: Orifice flow meters may be used to measure fluids under high temperature and high pressure conditions, such as steam, petroleum or chemicals. Metal spiral wound gaskets, especially those containing graphite or PTFE materials, can withstand higher temperatures and pressures, ensuring sealing reliability can be maintained under harsh working conditions.
3. Corrosion resistance: In chemical, petroleum and other industries, fluids are often corrosive to a certain extent. The combination of the outer metal layer of the metal spiral wound gasket and the inner non-metallic material (such as PTFE) can resist corrosion from a variety of chemical substances, extend the service life of the gasket and protect the flow meter from corrosion.
4. Compensation for unevenness: In actual applications, there may be minor unevenness on the flange surface. Due to its structural characteristics, metal spiral wound gaskets can compensate for these unevenness to a certain extent and ensure the sealing interface. Rigor.
5. Reduce maintenance: Compared with traditional asbestos gaskets, metal spiral wound gaskets are more durable, reducing frequent maintenance and replacement due to gasket failure, and reducing long-term operating costs.
In summary, for orifice plate flowmeters, metal spiral wound gaskets are not only a necessary component to achieve effective sealing, but also a key component to ensure measurement accuracy, equipment stability and safety.
