Butt welding flange gasket material and sealing performance

　　According to the pressure of different grades and butt welding flange gasket also have different materials, from the low-pressure asbestos pad, high pressure asbestos pad to the metal pads. Welding neck flanges in the actual production and the development of the different ways and process for production and, according to the process and principle, to different aspects of produce important value and function. In the actual production add certain elements increase the characteristics and value of carbon steel flange, good use features and value. Flange connection is convenient to use, able to withstand greater pressure.

　　In the industrial pipeline filter filter filter bag, welded flange is widely used. Within the family, the small diameter of the pipe and low pressure, invisible welded flange. If you are in a boiler room or in the production site, all the pipes and equipment are connected to the flange.

　　1. Connect the line and keep the sealing performance;

　　2, for the replacement of a pipeline steel; also called carbon steel, refers to the iron carbon alloy carbon content less than 2% WC.

　　Carbon steel in addition to the control valve of the valve gate valve carbon generally also contains a small amount of silicon, manganese, sulfur, phosphorus.

　　3, easy to open and check the pipeline situation;

　　4, to facilitate the closure of a certain section of the pipeline.
