The flange is mainly used to connect between the pipe ends.Apart from the connection use, the flange can also be used in toilet. Moreover, this product can also be used in the inlet and outlet of the device for connection, such as the reducer flange. The flange plays a significant role in the pipeline system. There are holes in the flange, and the bolts make the two flanges connected. Two flanges are connected by the liner. The flange boast a great number of types, in this paper, the author would like to introduce the classification of flange.
In general, the flange can be divided into several types, which include the threaded flanges, welded flanges and clip flanges. Flanges are used in pairs, and the low pressure pipes can be used with wire-bonded flanges, which is mainly used for the pressure above four kilometers. The classification of flange can be described as following.
In accordance to the standard of chemical industry, the flange mainly include the integral flange (IF), threaded flange (Th), plate flat weld flange (PL), neck butt weld flange (WN), neck flat weld flange (SO), socket weld flange (SW ), butt ring loose flange (PJ/SE), flat weld ring loose flange (PJ/RJ), lining flange cover (BL(S)), flange cover (BL) and so on.
According to the standard of petrochemical industry, the flange can be classified into six types, such as the threaded flange (PT), butt weld flange (WN), flat weld flange (SO), socket weld flange (SW), loose flange (LJ), flange cover.
In terms of the mechanical industry standard, the flange mainly include integral flange, butt weld flange, plate flat weld flange, butt weld ring plate loose flange, flat weld ring plate loose flange, flanged ring plate loose flange, flange cover.
According to the national standard, the flange can be divided in to several types, which mainly include the integral flange, threaded flange, butt weld flange, neck flat weld flange, neck socket weld flange, butt weld ring with neck loose flange, plate flat weld flange, butt weld ring plate loose sleeve Flange, flat welded ring plate loose flange, flanged ring plate loose flange, flange cover.
The above mentioned text is a brief introduction to the classification of flange, which can be classified in accordance with four different standards, including the chemical industry standard, petrochemical industry standard, mechanical standard, and the national standard. Different flange can be used in different situation, which plays a pivotal role in the pipe fittings. The most commonly used flange include: integral flange, threaded flange, plate lat weld flange, lining flange cover and so on.
