Zirconium flange

Zirconium flanges are used in a variety of applications in the chemical and process industries. They are typically used in high temperature and pressure applications, such as in the manufacture of heat exchangers and reactors. Zirconium flanges are an ideal choice for these applications because of their superior corrosion resistance and strength. Additionally, because of their strength and resistance to corrosion, zirconium flanges are an excellent choice for applications where high temperatures and pressures are present.

Zirconium flange: also called zirconium alloy flange, the connection mode is divided into flat welding/butt welding/insert welding connection, pressure resistance PN16~64, through DN15-DN800, for the connection between the pipe end; It is also useful in the flange of the import and export of the equipment, used for the connection between the two equipment for the conveying pipeline of qing fluoric acid and aqua aqua and other media, widely used in chlor-alkali industry, soda industry, pharmaceutical industry, fertilizer industry, fine industry, textile fiber synthesis and dyeing industry, basic organic acid and inorganic salt production, nitric acid industry, etc
With high temperature resistance, good corrosion resistance, machining, good performance and low thermal neutron absorption cross section comprehensive performance, is an important structural material for nuclear reactor, zirconium and alloy in various concentrations of alkali solution and molten alkali is the only corrosion resistant material.
Principle of use
The flange is a part connected between the pipe and the pipe, used for the connection between the pipe end; Also useful in equipment inlet and outlet flange, used for connection between two equipment, such as reducer flange. Flange connection or flange joint, refers to the flange, gasket and bolt three mutually connected as a group of sealing structure detachable connection. Pipe flanges refer to the flanges used in pipe fittings and the import and export flanges used in equipment. There are holes in the flange, and the bolts make the two flanges tightly connected. The flanges are gasketed. Flange consists of threaded connection (thread connection) flange, welded flange and clamp flange. Flanges are used in pairs, wire flanges can be used for low pressure pipes, and welded flanges for more than 4 kg of pressure. Put a gasket between the two flanges and fasten them with bolts. Flanges of different pressures have different thicknesses, and they 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 plane around 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".

Application purpose:
Zirconium is mainly used in equipment with high corrosion resistance requirements, such as in the manufacture of reverse reactors, acid resistant heat pumps, heat exchangers, dips, exhaust impellers, valves, agitators, nozzles, thermocouple bushing, conduit and container lining and environmental protection equipment. Zirconium is used in many chemical equipment and important parts for the production of fertilizers, resins, plastics and acids.

Classification:
1. According to HG industry standard: integral flange (IF), threaded flange (Th), plate flat welded flange (PL), butt welded flange with neck (WN), butt welded flange with neck flat welded flange (SO), socket welded flange (SW), butt welded ring loose flange (PJ/SE), flat welded ring loose flange (PJ/RJ), lining flange cover (BL(S)), flange cover (BL).
2: According to the petrochemical (SH) industry standard: threaded flange (PT), butt welding flange (WN), flat welding flange (SO), socket welding flange (SW), loose sleeve flange (LJ), flange cover (not note).
3: According to the mechanical (JB) industry standard: integral flange, butt welding flange, plate flat welding flange, butt welding ring plate loose sleeve flange, flat welding ring plate loose sleeve flange, flanging ring plate loose sleeve flange, flange cover.
4: According to the national (GB) standard: integral flange, threaded flange, butt welded flange, flat welded flange with neck, welded flange with neck socket, butt welded ring with neck loose sleeve flange, flat welded flange, butt welded ring with loose sleeve flange, flat welded ring with loose sleeve flange, flanging ring with loose sleeve flange, flange cover.

Connection mode:
flange connections, which are used for two kinds of pipes, fittings, or devices, are first fixed in a flange flange, and between the two flanges, flange pads are bolted together, which completes the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, not visible flange connection. If you're in a boiler room or a production site, there are flanged pipes and equipment everywhere.

According to the connection method, the connection types of flange can be divided into: plate flat welded flange, neck flat welded flange, neck butt welded flange, socket welded flange, thread flange, flange cover, neck butt welded ring loose sleeve flange, flat welded ring loose sleeve flange, ring groove flange and flange cover, large diameter flat flange, large diameter high neck flange, figure 8 blind plate, butt welded ring loose sleeve flange, etc.
