Carbon steel plate flange
CS Flanges connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are Carbon Steel weld neck flange, Carbon Steel slip on flange, Carbon Steel blind flange, Carbon Steel socket weld flange, Carbon Steel threaded flange and Carbon Steel lap joint flange. Carbon Steel Blind Flangesare many different standards of flanges to be found worldwide. Common world standards include ASA/ANSI/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean), ASME B16.5 150#, 300#, 600#, 900#, 1500#, 2500# | BS EN1092-1 PN 10/16/25/40
Why and how steel flange working for pipeline system
The connection between two pipes can be directly welded together, but it is difficult to connect together without welding. When the connection part has problems, it will be hard to repair. The same problem also happened between pipe and valve connection.
Flange is usually used for connecting pipes or valves, so it can solve the above problems easily.
How many parts included in a flange connection?
The flange connection type usually comes with double units, with a gasket and some bolts & nuts to connect each other. (Firstly pipes are welded on the flanges, then valves and other equipment could be installed on flanges.)
When connecting these parts, put gasket in the middle of two flanges, then tightening the flange screws, so the two will be connected together tightly.
Flange Performances
Flange connection has good strength and sealing, simple structure and low cost. It can be repeatedly disassembled.
Failure mode
The flange connection mainly has a leakage problem, and the leakage quantity should be controlled within the allowable range of process and environment.
Carbon Steel Flange is made of the material production of carbon Steel Flange, and flange is a kind of used to connect piping accessories. Connections are welding, thread, the three CARDS. Carbon steel flange forging, casting, medium plate rolling production process, medium plate cutting system, etc. Second forging of the highest prices, medium plate products, casting products are the lowest. Standards: machinery to standard JB/T81-94, chemical standard HG20593-97, HG20617-97, the national standard GB/T9119-2000, Marine standard CB M1001-81, thermal power D - GD87-1101 standard.Compared with ordinary carbon steel flange material Q235B, 20 #, 16 mn, 45 # steel, Q345B material, etc.
National standard flat flange are suitable for pressure or temperature fluctuations of the pipeline or high temperature, high pressure and low-temperature pipes, mainly used for conveying is expensive, inflammable, explosive medium on the pipeline.This product is not easy to deformation, good sealing, wide application, it is the nominal pressure of PN at about 16 map. Butt welding flange connection is convenient to use, can withstand greater pressure. National standard flat flange production and executive standard: gb, American standard, Japanese standard, German standard, the standard of Italy.National standard flat flange production standard GB/T9119-2000. HG2052 ~ 20635, JB81-94, and the CBM standard flange (ship), etc.Moreover in 2009 flange to the country's nuclear power projects.
