A brief introduction to SO flange
Because the neck height is low, the stiffness and bearing capacity of SO flange flange with neck are improved, and the site installation is more convenient and popular. Do you know what components SO flange is made of? How does SO flange work? Below, for everyone a brief introduction, for everyone to understand.
But before we get to the questions that SO flange works, what kinds of flange are made of. SO flange plates include a flange with an inner hole in the center and multiple screw holes in the flange. A neck boss is arranged on one side of the flange, whose inner diameter is equal to the inner hole and is connected to each other. The other side of the flange has a circular depression with a center that overlaps the central axis of the inner hole and a radius greater than the radius of the inner hole.
Because of structural characteristics such as SO flange (annular indentation overlapping circular indentation),SO flange is inserted into the body hole for lap welding. A three-dimensional weld can be formed between the pipe body material and the flange material to improve the welding stability between the flange and the pipe body. In other words, the neck of SO flange is shorter, which increases the strength and carrying capacity of the flange and can be used in high-pressure pipes.
Well, the above is an introduction to the structure and working principle of SO flange flange. Advantages and disadvantages of SO flange
SO flange is mainly used for gas valves and natural gas pipelines. Because the short neck can improve the stiffness and bearing capacity of the flange. Plate welded flanges are used for general media. SO flange flange is suitable for inflammable, explosive, corrosive, toxic places. The sealing surface of SO flange flange can be convex surface, concave and convex surface and tenon surface. They differ in construction, sealing effect and strength.
SO flange are generally called flat plates, also known as lap welded flanges. Flat weld the connection of the flange to the pipe. Insert the pipe into the flange hole to the appropriate position before lap welding.
The sealing surface forms of SO flange with neck are:
Convex surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full plane (FF)
SO flange diameter range: DN10~600
Applicable scope: PN series PN2.5~PN40; The Class series is Class150 to Class1500
Manufacturing process: forging
There are two main international pipe flange standards, namely the European pipe flange system represented by German DIN(including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flange.
In addition, there are Japanese JIS tube flanges, but in petrochemical installations are generally only used for public works, and the international impact is less.
The SO flange is connected to the pipe end. It is mainly a part that connects pipes to pipes. SO the flange has holes, can wear bolts, so that the two flanges are tightly connected, flange with a gasket seal.
