The Role of the Flange in Pipeline Equipment

Flange through welding methods, such as flat welding, butt welding, socket welding, connected with pipe, equipment and containers by threaded connection, clamp connection. Through the connection between the two flanges to connect the pipe and pipe, pipe and equipment, forming the pipe line, which is the role of the flange in the pipeline equipment. The connection between the two flanges is that adding the gasket in the middle of the flange, by a sealed and detachable connection way which is combined by the bolt-on.

Flange is the most commonly used in pipe fittings, flange as well as elbow, tee, valves and other pipe fittings connecting the pipeline with equipment together. In the use process, due to the different transportation medium, different temperature, different flow, which leads to the pipe length, horizontal height and pressure produced by concrete pump power are different. Consumers should pay special attention to material and quality of products in the selection of piping components and accessories. Purchasing pipes and pipe fittings, consumers should carefully adhere to the national and international standards, that means consumers should do full design and evaluation of the size, pressure of product, according to the need for carbon steel, alloy steel, stainless steel pipe fittings and other materials and fittings to make careful selection. What’s more, the quality of pipe fittings and technical requirements, production and testing processes should be strictly controlled.

The material of flange can be divided into: WCB (carbon steel), LCB (low temperature carbon steel), LC3 (3.5% nickel steel), WC5 (1.25% 0.5% chrome molybdenum steel), WC9 chromium (2.25%), C5 (% 5% chromium molybdenum), C12 molybdenum chromium (9% 1%), CA6NM (4 (12% chromium steel), CA15 (4) (12% chromium), CF8M stainless steel (316), CF8C stainless steel (347), CF8 stainless steel (304), CF3 (304 l stainless steel), CF3M (316 l stainless steel), CN7M (alloy), (monel), N7M M35-1 (B) hastert nickel alloy, CW6M nickel alloy C (Hastur tower nickel alloy), CY40 (Inconel nickel alloy) and so on , consumer can choose according to need.

There are many kinds of flanges, such as welding plate flange, slip-on flange, welding neck flange, socket welding flange, threaded flange, flange cover, butt welding ring loose set flange, welding ring loose flange, ring groove face flange and flange, flange plate with large diameter, large diameter high neck flange, blind flange and so on. Type, size from the nominal diameter of DN10 to DN4000; shape from the round, square, oval to various shapes can be processed.

In the purchase, sale and use process, it should be in according to the use purpose, it is recommended to comply with the design principles, adopt the standard pipe fittings products and select the standard series of flanges to ensure quality and safety of the project. In view of the practical application, there are the choice of non-standard, second standard flange, please use carefully to ensure that the project quality and safety. Considering the construction and operating costs, at the same time, pursuing the safety of production and economic benefits.
