Q:What is the flange? What are its application areas and principles?

Flanges (Flange), also called flanges, flanges, or flanges. 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.Flanges are widely used in construction, power generation, machinery and many other fields, and their main functions are as follows:1. Connect the pipe and keep the sealing performance of the pipeline.2, to facilitate the replacement of a section of the pipeline.3, easy to disassemble check the pipeline.4, to facilitate the closure of a section of the pipeline.Classification of flanges1. carbon steel, cast steel, alloy steel, stainless steel, copper and aluminum alloy are classified by material2., the production method can be divided into forging flange, casting flange, welding flange and so on.3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB).

Q:What is the silk flange?

Generally refers to the pipe, pipe connections, the commonly used way is divided into: silk and flange two. The screw thread is a screw thread connection; the flange is to weld the two end of the connecting pipe on the convex ring, drill a few holes, and penetrate the bolt in the hole to connect."Wire flange" is the combination of two ways, is a separate connection, that is, pipe flange thread connection, the flange is not welded to the pipe end, but threaded with the pipe end connection.

Q:How many kinds of flanges do you have? Does anyone know a more specialized classification?

There are many kinds of flange, mainly due to the nominal diameter (A type B type, namely the metric system), nominal pressure, use of structure, material, sealing surface form, connection mode classification (diameter and pressure rating not included) according to the form of: flange welding plate flange (PL), hubbed flange (SO), neck flange (WN), integral flange (IF), socket welding flange, threaded flange (SW) (Th), welding ring flanges (PJ/PE), ring flanges (PJ/JR); according to the sealing surface form: process surface (RF), convex surface (MFM) and the tongue and groove face (TG), the whole plane (FF) and ring junction (RJ); this does not include the flange; according to the material: cast iron, cast steel, forging, flange, stainless steel flange, Q235 plastic flange etc..

Q:What are the advantages of a flanged plunger valve?

The structure characteristics of the plunger valve is composed of a stainless steel plunger, two elastic sealing ring and a metal frame, the sealing effect by the plunger and the seal ring is closely fitted to the plunger, inserted in the two sealing ring, the sealing area is far greater than the ordinary valve; switch plunger valve, the piston moves slowly in the the sealing ring, the contact surface is almost not wear off, the plunger is inserted into the lower sealing ring, truncated channel; open, although from the plunger seal, but still hiding in the ring, remain isolated from the outside, not to leak.The sealing ring is a science and technology product. It is the key component of the plunger valve. It consists of polytetrafluoroethylene, graphite and high elastic rubber. It can provide good sealing performance after millions of times of reciprocating movement test. Meanwhile, the valve has small opening moment, large sealing area, wide application medium, high temperature adaptability, reliable sealing, long service life, convenient maintenance and the like. Widely used in petroleum, chemical, power, pharmaceutical, food, textile, printing and dyeing, boilers, machinery and other industries.
