Flange (Flange) , also known as Flange or Flange plate.
Flanges are parts that connect pipes with pipes and are connected to pipe ends;
Also useful in the equipment inlet and outlet flange, used for the connection between two equipment, such as reducer flange.
Flange connection or flange joint refers to the detachable connection of a group of combined sealing structure made up of flanges, gaskets and bolts. Pipe flange refers to the flanges of pipe fittings in pipeline devices, and refers to the inlet and outlet flanges of equipment when used in equipment.
There are holes in the flanges and bolts hold the two flanges together.
Use gasket to seal between flanges.
Flanges are divided into thread connection (thread connection) flange, welding flange and clamping flange.
According to the production material can be divided into: WCB (carbon steel), LCB (low temperature carbon steel), LC3 (3.5% stainless steel neck butt welding steel pipe flange
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 (haas tower nickel alloy C), CY
40 (for nickel alloy) http://www.buxiugangbang.cc
Flanges from small to large, the common specifications are:
DN10, DN15, DN20, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN
175, DN200, DN225, DN250, DN300, DN350, DN400, DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1200, DN1400, DN1600, DN1800, DN2000, DN2200, DN2400, DN2600, DN2800, DN3000, etc.
Flanges 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
(Hastert nickel alloy B), CW6M (Hastert nickel alloy C), Cy40 (Inco nickel alloy)
Flange connection method: namely two pipes, pipe fittings or equipment, first respectively fixed on a flange, between two flanges, plus flange pad, with bolts connected together, completed the connection.
Some pipe fittings and equipment have their own flange, also belongs to the flange connection.
This connection is mainly used for the connection of cast iron pipes, rubber lining pipes, non-iron metal pipes and flange valves, and the connection of process equipment and flanges is also used for flange connection.
The main characteristics of flange connection are convenient disassembly, high strength and good sealing performance.
When installing the flange, the two flanges should be kept parallel, the sealing surface of the flange should not be damaged, and should be cleaned.
The gasket used for the flange should be selected according to the design regulations.
Flange connection is an important connection way in pipeline construction.
Flanges are threaded connection (wire) flanges and welding flanges.
Low pressure small diameter wired flange, high pressure and low pressure large diameter are welded flange, flange thickness and connecting bolt diameter and number of different pressures are different.
According to the different levels of pressure, flange gaskets are made of different materials, from low pressure asbestos gaskets, high pressure asbestos gaskets to metal gaskets.
Flanged connection is easy to use and can withstand greater pressure.
Flanged connection is widely used in industrial pipelines.
In the home, the pipe diameter is small, and the pressure is low, the flange connection is not visible.
If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
