Product Description
Blind flanges, also known as blind flanges, are a type of pipe fitting used in pipeline systems. The following is a detailed introduction for you:
Structural Features: A blind flange is actually a flange without a central through hole. It has a similar appearance to an ordinary flange and comes in various specifications and sizes. Its sealing surface forms are diverse, including full face, raised face, male and female face, tongue and groove face, and ring joint face, etc., to adapt to different working conditions and sealing requirements.
Working Principle: It is mainly used to block the end of the pipeline to prevent the flow of the medium inside the pipeline, playing the role of isolation and disconnection. The blind flange is connected to the mating flange on the pipeline through bolts, and the sealing surface of the flange and the gasket are used to achieve sealing, ensuring the sealing performance and safety of the pipeline system.
Application Fields: It is widely used in pipeline systems in many industrial fields such as petroleum, chemical industry, natural gas, electric power, water supply and drainage, etc. For example, in chemical plants, when a certain pipeline branch needs to be temporarily or permanently closed, a blind flange will be used for blocking. In the circulating water system of the power industry, blind flanges are also used to isolate different parts of the pipeline, making it convenient for equipment maintenance and repair.
Installation and Maintenance: During installation, it is necessary to ensure that the sealing surfaces of the blind flange and the mating flange are clean and free of damage, the gasket is installed correctly, and the bolts are tightened evenly to ensure the sealing effect. During the maintenance process, regularly check the sealing performance of the blind flange, check whether the bolts are loose, whether the gasket is aged and damaged, etc. If there are any problems, replace the relevant parts in a timely manner to ensure the safe operation of the pipeline system.
