The carbon steel flange according to the seal surface different has many kinds of classification, the flange seal surface form and the use environment has the direct relations, below the small plait to take everybody to understand each kind of different seal surface. 1. The whole plane of the sealing surface type (FF): More for the flat

The traditional high pressure flange has the following characteristics:   1. The high pressure flange is connected by bolts; 2. Its sealing principle is plastic deformation to achieve sealing effect; 3. The high-pressure flange is generally large in volume, so it is relatively difficult to install and position the high-pressure flange; 4. The bolts of

Flange is a commonly used part in engineering, covering a wide range of fields, because it is an indispensable part of piping design, piping fittings and valves. The difference between standard flanges and non-standard flanges is mainly reflected in the following aspects: Flange specifications The national standard flange is a general-purpose component. The outer diameter,

The FIGURE 8 BLIND FLANGE is a kind of pipe parts, mainly for convenience of maintenance. You can paint the upper part of “8” into black in the specific shape. It’s half blind, half is a ring. It is commonly used for the pipe flange which needs to change the process. The material mainly includes carbon

1. standard GB/T14383–93, GB/T14383–2008, ASME B16.11, petrochemical standard SH3410, Ministry of chemical industry standard HG/T21634. According to the form, it can be divided into 45 degree socket elbow and 90 degree socket elbow. According to the form of pipe, it can be divided into socket elbow and threaded elbow. According to the standard, the specifications

Now many people will come into contact with the flange, but do not know what kind of flange in the end is what kind of thing, flange appears in people’s lives everywhere, the following to elaborate on the use of carbon steel flanges and connections. Flange connection is the two pipes, fittings or equipment, first fixed in

Pipe flange and its gasket and fastener are collectively referred to as flange joint. 1. Application Flange connection is widely used in engineering design. It is an essential part of pipeline design, pipe fittings, valves, etc. It is also an important part of equipment components. In addition, industrial furnace, heating, drainage, heating and ventilation, automatic

Type discrimination of alloy steel flange. Different from ordinary 20 #, Q235 and other carbon steel flanges, it is mainly used for special characteristics of pipelines and pipelines, mostly for high temperature and high pressure positions. Its common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910 and so on. The implementation standards include national standards, Ministry of Chemical
