Some fittings and equipment have built-flange, flange connection also belongs.Flange sub-thread connection (screwed) flange and welding flange. Low voltage and small diameter wire connected flange, high pressure and low pressure large-diameter welded flanges are used, different pressure flange thickness and bolt diameter and number of connections is different.According to different levels of pressure, flange pad also has a variety of materials, asbestos from the low pressure pad, pressure pad to the metal pads are asbestos.Flange easy to use, able to withstand greater pressure.In the industrial pipe, the flange connection using a wide range. Within the family, small diameter pipes, but also low pressure, see flange connection. If a boiler room or a production site, full of flanged pipe and equipment.
