Flanges are disk-shaped parts, most common in pipeline engineering, and flanges are used in pairs.
Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flanges are divided into threaded connection (wire connection) flanges and welded flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connection bolt diameter and number are different.
Titanium flange has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, health, water heating, fire, power, aerospace, shipbuilding and other basic engineering.
Feature
The neck flat welded flange, like the plate flat welded flange, is also a flange that extends the , pipe fittings, etc. into the flange and connects with the equipment or pipe through the fillet weld.
Seal form
The sealing surface forms of flat welded flange with neck are:
Convex surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full plane (FF).
Diameter range of neck flat welded flange: DN10~DN600.
Scope of application
PN series PN2.5~PN40; Class Series Class150 to Class1500
Advantages: Flat welded flange with neck is also a flat welded flange, because it has a short neck, which improves the strength of the flange and improves the bearing strength of the flange. Therefore, it can be used for higher pressure pipelines, PN series PN2.5~PN40; Class Series Class150 to Class1500
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. In addition, there are Japanese JIS pipe flanges, but they are generally only used for public works in petrochemical installations, and have less impact internationally. The pipe flanges of various countries are introduced below:
1, the European system pipe flange represented by Germany and the former Soviet Union
2, the American system pipe flange standard, represented by ANSI B16.5 and ANSI B 16.47
3, British and French pipe flange standards, the two countries each have two casing flange standards.
To sum up, the international standard of pipe flanges can be summarized as two different, and not interchangeable pipe flanges system: a European pipe flanges system represented by Germany; The other is the American pipe flange system represented by the United States.
IOS7005-1 is a standard issued by the International Organization for Standardization in 1992, the standard is actually the United States and Germany two series of pipe flanges merged into the pipe flanges standard.
