Forged flange is a common pipe connection and is widely used in the industrial field. Its sealing performance is usually good, with the following advantages: high sealing: The forged flange is made of metal materials, through the bolt fastening, can achieve high sealing performance. The uniform force of the bolt acts on the gasket between the flanges, making the flange connection have a good sealing effect. Strong compressive performance: the forged flange has high compressive performance and can withstand greater pressure and impact load. Under harsh conditions such as high temperature and high pressure, its sealing performance will not be significantly affected. Good corrosion resistance: Metal materials commonly used in forging flanges, such as stainless steel and carbon steel, have good corrosion resistance and can adapt to the transportation requirements of various media, so as to ensure the lasting stability of sealing performance. Easy and reliable installation: the forged flange has the characteristics of unified interface specifications, convenient and quick installation. And because of its simple structure and reliable connection, it is not easy to leak. These advantages make forging flanges widely used in engineering practice. It should be noted that when selecting and using forged flanges, appropriate materials and specifications should be selected according to the specific working conditions and medium properties to ensure the reliability and stability of its sealing performance. At the same time, during the installation process, it is necessary to operate in accordance with relevant standards and regulations to ensure that the fastening strength and sealing performance of the flange connection meet the requirements.
