Flange gasket seal. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. All flanges are used in pairs, and the low pressure pipe can be used for the use of wire connecting flanges, and the use of four kg or more pressure on the use of welding flanges. Between the two pieces of the flange and the sealing pad, and then use the bolt fastening. Different pressure flange thickness, the use of bolts are also different
