Flange basic introduction
Pipe flanges and their gaskets and fasteners are collectively referred to as flange joints.
Pipe flanges and their gaskets and fasteners are collectively referred to as flange joints.
Applications:
Flange joint is a kind of component which is widely used in engineering design and involves a wide range of areas. It is an essential part of pipe design and pipe fitting valves, and it is also a necessary component in equipment and equipment components (such as manholes, sight glasses, liquid level gauges, etc.). In addition, other professions such as industrial furnaces, thermal engineering, water supply and drainage, heating and ventilation, automatic control, etc., also often use flange joints.
Material:
Forged steel, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chromium molybdenum steel, chromium molybdenum vanadium steel, molybdenum dititanium, rubber lined, fluorine lined material.
Categories:
Flat welded flange, neck flange, butt welded flange, ring joint flange, socket flange, and blind plate, etc. Implementation standards: GB series (national standard), JB series (Mechanical department), HG series (chemical department), ASME B16.5 (American standard), BS4504 (British standard), DIN (German standard), JIS (Japanese standard).
International pipe flange standard system:
There are two main international pipe flange standards, namely, the European pipe flange system represented by the German DIN(including the former Soviet Union) and the American pipe flange system represented by the American ANSI pipe flange.
Neck butt welded flange - one of 12 kinds of flanges
The sealing surface forms of the neck butt welded flange are: convex surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full plane (FF).
Advantages:
The connection is not easy to deform, the sealing effect is good, and it is widely used, suitable for pipelines with large fluctuations in temperature or pressure or pipelines with high temperature, high pressure and low temperature, and also for pipelines with expensive media, inflammable and explosive media and toxic gases
Disadvantages:
The flange with neck butt welding is large in volume, heavy in weight, expensive and difficult to install. Therefore, it is more likely to bump in transit.
