1.What are the common sealing methods and technologies for Flange And Ring Parts?In the engineering design and manufacturing process, sealing technology plays a vital role in flange connections. Different sealing methods and technologies are used in different working environments and requirements to ensure the stability and sealing of flange connections. Generally speaking, sealing technology is designed to prevent liquid or gas from leaking from flange connections and to maintain the stability and sealing of the connection.
Gasket sealing is a common sealing technology that uses gaskets placed between flange joint surfaces to achieve sealing. These gaskets are usually made of a soft material (such as rubber, polymer or metal). When the flange is connected, the gasket is squeezed and fills the unevenness of the connecting surface to form an effective seal. Gasket seals are suitable for flange connections under various pressure and temperature conditions and have good sealing performance and reliability.
Metal sealing is a common sealing technology used under high temperature and high pressure working conditions. Metal seals typically use metal-to-metal contact between metals to achieve sealing, which provides a solid connection and effective sealing performance. Metal seals are suitable for applications requiring higher pressure resistance and temperature resistance, and have higher sealing performance and durability.
In addition, O-ring sealing is a simple and effective sealing technology. It sets an O-ring sealing groove around the flange connection surface and installs the O-ring in it. When the flange is connected, the O-ring is squeezed and forms a seal around the connecting surface. O-ring seals are suitable for low-pressure and low-temperature working conditions, with simple installation and good sealing performance.
Threaded seals and welded seals are two different types of sealing technologies that are suitable for different types of flange connections. Thread sealing is usually achieved using thread sealant or sealant, which is applied to the threaded portion of the flange connection to prevent liquid or gas leakage. Welding sealing is achieved by welding the flange connection. This sealing technology is suitable for applications requiring higher sealing performance and strength.
Flange face sealing is a high-precision sealing technology that utilizes the flatness and smoothness of the flange connection surface to achieve sealing. This sealing method is suitable for application scenarios that require higher sealing performance and precision, such as high-precision instruments, aerospace and other fields.
Sealing technologies play an important role in flange connections, and their selection depends on specific working conditions and requirements. Therefore, when designing and selecting sealing methods, factors such as application environment, pressure, temperature, liquid or gas medium, etc. should be fully considered to ensure the stability and sealing of the connection.
