Flanges and blind plates are two widely used sealing connection components in industries, construction, and pipeline engineering. A flange is used to connect two or more pipelines or equipment, and has various forms and specifications. It can be plate type flat welding flange, neck welding flange, neck welding flange, integral flange, socket welding flange, threaded flange, butt welding ring loose sleeve flange, flat welding ring loose sleeve flange, flange cover, lined flange cover, American standard neck welding flange, American standard neck welding flange, etc. According to the different materials, common flanges include forged steel, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chromium molybdenum steel, chromium molybdenum vanadium steel, molybdenum titanium, rubber lining, fluorine lining, etc.

Blind plates are used to close or cut off the flow of pipelines or equipment, and are a type of isolator. Unlike flanges, blind flanges do not need to be connected to other components. Their principle is to use liquid to penetrate the sealing surface and working surface to form a gap to reduce friction, while automatically loosening the fastening bolts to open the valve. They are suitable for automatic control devices of small diameter piping and for use at the outlet of hydraulic equipment. According to different usage environments and purposes, blind flanges can be divided into shut-off check valves, lifting plug valves, ball valves, diaphragm valves, butterfly valves, gate valves, and other control components in pipeline systems.
