In the industrial pipeline system, the gran head is an important component of connecting pipelines, and its size is directly related to the stability and tightness of the pipeline connection. The correct selection of the right size gran head is essential to ensure the safe operation of the piping system. Let's discuss the relevant content of the size and size selection of the granulated head:

Size parameters: The size of the gran head is usually determined by three parameters: pipe diameter, flange thickness and flange diameter. Pipe diameter refers to the outer diameter or inner diameter of the pipe, usually in inches or millimeters, such as 1/2 inch, DN50, etc. Flange thickness refers to the thickness of the flange, used to support the connection and ensure sealing performance; The outside diameter of the flange refers to the outside diameter of the flange, which determines the connection method and specification of the flange. When selecting the gran head, it is necessary to select the corresponding gran head size according to the caliber and pressure of the pipeline and other parameters to ensure that the connection with the pipeline matches.

Size selection: The size selection of the gran head needs to consider a number of factors, including the working pressure of the pipeline, temperature, medium type and connection method. For pipeline systems under special working conditions such as high pressure, high temperature, flammable and explosive, it is usually necessary to choose a larger size of the gran head to ensure the safety and reliability of the connection; For piping systems under normal working conditions, smaller sizes of gran heads can be selected to meet connection needs and reduce costs. In addition, according to the requirements of engineering design and pipeline layout, it is also necessary to choose the appropriate connection mode, such as flange connection, threaded connection, etc.

Standard specifications: The size and size selection of gran head usually comply with international standards or industry specifications, such as ANSI/ASME, DIN, JIS, etc. In the selection process, it is necessary to select according to the specific standard specification requirements, and ensure that the size and size of the gran head meet the corresponding standard requirements to ensure the connection quality and safety performance.

In summary, knowledge of the size and size selection of the gran head is essential for the correct selection of the appropriate pipe connection components. In the process of engineering design and pipeline installation, we will scientifically select the appropriate size of the gran head according to the specific engineering needs and standard specifications, to ensure that the pipeline connection is stable and the seal is reliable, providing a reliable guarantee for industrial production.
