    What is a ANSI B16.5 class 300 flange?

    The flange is a part that connects the pipe and the pipe to each other, which is connected to the end of the pipe; it is also used on the equipment import and export of flanges for connections between two equipment, such as decelerator flange. Flange connection or flange joint, refers to the flange, gasket and bolt three mutually connected as a group of sealing structure detachable connection. Pipeline flanges refer to the flanges used in pipeline fittings and the import and export flanges used in equipment.

    Advantages of the ANSI B16.5 class 300 flange:
    1.Carefully selected material
    The quality from the raw material to factory through layers of checks, good performance, and peace of mind.
    2.Rigorous technology
    Uniform distribution of bolt holes, accurate positioning and high matching degree.
    3.Good anti-pressure capacity
    The surface of the flange is smooth, no bubble bearing capacity is good, and it is easy to install.
    4.Use flexibly
    Dimension cutting adopts CNC operation, small errors, adapting to high temperature and harsh environments.

    Pipe fittings as the mandatory accessories in pipeline, WESDOM also could provide wide range of standard and materials to match your pipes and valves. One stop service, save your time, save your Slip-on pipe flange generally slide on the pipe. Socket-type pipe flanges are usually made with the inner diameter of the pipe flange slightly larger than the outer diameter of the pipe. This allows the sliding flange to slide over the pipe.
