PN10 DN400 Blind Flange

To put it simply, the blind plate is a robust flange used to shut the cease of the pipe.
Generally used in the feed water branch pipe end. There is a short part of the pipe location to first stress take a seem at used for quick closure.
Flanges are disk-shaped parts, most mostly used in pipeline engineering. Flanges are used in pairs.
In pipeline engineering, flange is essentially used for pipeline connection. In the prefer to be part of the pipe, pretty a range set up of a flange, low stress pipe can use wire flange, the use of larger than 4 kg of stress welded flange. Put a seal between the two flanges and fasten them with bolts. Flanges of one of a form pressures have particular thicknesses and use particular bolts.
Water pumps and valves, when linked with pipes, the local elements of these equipment are moreover made into the corresponding flange shape, moreover viewed as flange connection.
All in the two planes in the periphery of the use of bolt connection at the equal time closed connection parts, typically recognised as "flange", such as the connection of air float pipe, this kind of factors can be recognised as "flange class parts".
But this connection is completely a section of the equipment, such as the connection of the flange and the water pump, it is now now not right to title the water pump "flange parts". Relatively small, such as valves, can be acknowledged as "flange parts". Flange connection is an imperative connection mode in pipeline construction. Flange connection is the two pipes, pipe fittings or equipment, respectively consistent on a flange plate, between the two flanges, plus flange pad, bolted together to entire the connection. Some pipe fittings and equipment have their very very own flange, moreover belong to the flange connection.

Product Details

PN10 refers to the pressure rating of the flange, which is 10 bar. DN400 refers to the nominal size of the pipe that the blind flange fits on, which is 400mm. A blind flange is a type of flange that is used to seal the end of a pipe or valve. It is typically used in situations where it is necessary to block off a section of piping or equipment for maintenance or repair..
