the different levels of stress

　　According to the different levels of stress, butt welding flange gasket also have different material, from the low pressure asbestos pad, high-pressure asbestos pad to metal pads. Development of butt welding flange in the actual production and used in different ways and process of production and the production, according to the process and principle, and have important value and role of different, in the actual production to add some elements increase the features and value of carbon steel flange, do well the use of the characteristics and value. Flange connection is convenient to use, can withstand greater pressure.

　　In industrial pipe butt welding flange connection is widely used. Within the family, pipe diameter is small, and it is low voltage, invisible butt welding flange connection. If in a boiler room or production site, the flange connection of pipes and equipment are everywhere.

　　1, the pipeline of pipeline connection and keep the sealing property;

　　2, easy to change line a long period; Carbon steel or carbon steel, carbon content WC is less than 2% of the iron carbon alloy.

　　Carbon steel in addition to carbon generally contain small amounts of silicon, manganese, sulfur and phosphorus.

　　3, easy to disassemble pipeline;

　　4, easy to pipeline closed a long period.

　　We have adopted advanced production equipment and technologies to manufacture our plate flange and ANSI 300LB BLIND FLANGES, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
