PN16 DN600 Blind Flanges

To put it simply, the blind plate is a solid flange used to close the end of the pipe.

Generally used in the feed water branch pipe end. There is a temporary part of the pipe section to first pressure test used for temporary closure.

Flanges are disk-shaped parts, most commonly used in pipeline engineering. Flanges are used in pairs.

In pipeline engineering, flange is mainly used for pipeline connection. In the need to connect the pipe, various installation of a flange, low pressure pipe can use wire flange, the use of more than 4 kg of pressure welded flange. Put a seal between the two flanges and fasten them with bolts. Flanges of different pressures have different thicknesses and use different bolts.

Water pumps and valves, when connected with pipes, the local parts of these equipment are also made into the corresponding flange shape, also known as flange connection.

All in the two planes in the periphery of the use of bolt connection at the same time closed connection parts, generally called "flange", such as the connection of ventilation pipe, this kind of parts can be called "flange class parts".

But this connection is only a part of the equipment, such as the connection of the flange and the water pump, it is not good to call the water pump "flange parts". Relatively small, such as valves, can be called "flange parts". Flange connection is an important connection mode in pipeline construction. Flange connection is the two pipes, pipe fittings or equipment, respectively fixed on a flange plate, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection.
