FAQ

What is a flange? Where is it usually used?

A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms.

Who knows, the difference between plate flange and hubbed flange in the application.

Welding plate flange for general medium.Hubbed flange suitable for the inflammable and explosive, corrosive, toxic high placesThe sealing surface of flange plate are raised face (RF), hubbed flange sealing surface can be used from surface, convex surface, tongue and groove face.The two structures are different, the sealing effect is not the same, the strength is not the same.

Oil seal flange

Flange (flange) high pressure flange (SAE flange JBZQ 4187-97), also known as flange or flange. A part that connects the pipe to the pipe and is connected to the end of the pipe. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Fittings pipe (flanged) means a pipe with flanges (flanges or plates). It can be formed by casting and (figure not available), may also be threaded or welded together. The flange joint (flange, joint) consists of a pair of flanges, a gasket, and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. A flange connection is a detachable connection. The connecting parts can be divided into vessel flange and pipe flange. According to the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure.

What is the function of the flange stub?!

Flange is a kind of discoid parts, which is the most common in pipeline engineering. The edge has bolted mechanical structures, such as pipe joints, which can be bolted if flanges are attached to the flange. The flange cap is the flange of the cap and is bolted to the flange. Flanges are used in pairs.

There are 32; 3, 11/2, and so on, please master pointing, by the way, such tagging is based on what standards.

These refer to flanges,The 6 refers to DN150, 11/4 to DN32, 3 DN80, 2 DN50, 11/2 refers to the DN40 standard, American Standard so marked

Is the flange fitted with a flange?

Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges".

What is blind through flange?

The through flange is used to connect the two pipe fittings, and the two flanges are connected together by bolts. For the blind flange end of the pipeline, to shut off the pipeline

When the toilet is fitted with flanges, is the rubber side of the flange facing the floor or the toilet? The installation is more reasonable

1, the rubber ring side is toward the toilet, so that the toilet seat in the water outlet is easy to correct, it is best to ground glass glue, so that sealing is more difficult to leak.2, the flange ring is the sealing ring, also known as gasket. Currently more popular is the wax seal ring, also known as the wax sealing ring. Among the many industrial bearing to shock and wear resistant rubber pad called flange, basically need to use the toilet installation flange, but a lot of the toilet to reprovision. There is butter, polymer, the latter is more popular. The toilet (toilet flange seal) is put down the hole and the bathroom in the outfall, seals play a role, so that the siphon toilet flushing does not leak, the effect is very good.
