Rotary flange
1. The rotary flange is mainly used for connection of submarine and underwater pipelines. The outer ring of the rotary flange allows 360° rotation centering on the inner ring to quickly align the bolt hole of the corresponding standard flange. This feature is vital to submarine pipeline operation. It can make the diver align the bolt hole quickly and conveniently.
Slip-on plate flange
2. Slip-on plate steel flange is applicable to pipelines featuring low pressure rating and not severe pressure surge, vibration and oscillation. Slip-on flanges featuring easy alignment in flange welding and assembly and cheap price have been widely applied.
Galvanized flange
Galvanized flanges feature good anti-corrosion property. Galvanized flanges can be classified into the hot dip galvanized flange and the cold galvanized flange.
Flat flange
The flat flange also called slip-on plate steel flange is applicable to pipelines featuring low pressure rating and not severe pressure surge, vibration and oscillation. Slip-on flanges featuring easy alignment in flange welding and assembly and cheap price have been widely applied.
Blind plate
Blind plate is also called flange cover or blank flange. It is the flange on whose center there is not a hole. It is used for blocking the pipe opening.

Glange cover
The flange cover is also called blind plate or blind flange. It is the flange on whose center there is not a hole. It is used for blocking the pipe opening.
Blind flange
Blind flange is also called blind plate or flange cover. It is the flange on whose center there is not a hole. It is used for blocking the pipe opening.
Threaded flange
The threaded flange also called screw thread flange is a non-welded flange. Compared with the slip-on plate flange or the WN flange, the threaded flange can be installed and repaired conveniently. The inner hole of the flange is machined into a pipe thread. The flange and the pipe are not connected through welding, but through threads, that is, threads of the inner hole are produced through lathing, threads of the pipe are produced too, and then they are connected.
Screw thread flange
Wire buckle flange, also known as thread flange, is a non-welded flange. Compared with welding flange or butt welding flange, wire buckle flange has the characteristics of convenient installation and maintenance. It is to process the inner hole of the flange into pipe thread. The connection mode of the flange and the pipe is not welded, but the threaded connection mode, that is, the inner hole of the flange is threaded, the pipe on the pipe is threaded, and then the corresponding thread is connected.
Threaded flange
The threaded flange also called screw thread flange is a non-welded flange. Compared with the slip-on plate flange or the WN flange, the threaded flange can be installed and repaired conveniently. The inner hole of the flange is machined into a pipe thread.

SORF flange
Full name of neck flat welded flange with neck flat welded steel pipe flange English name :Slip-on for short SO flange.
Lap joint flange
Loose sleeve flange is also known as loose sleeve flange, sliding sleeve flange.
WN flange
Butt welded flange full name with neck butt welded steel pipe flange, also known as WN flange. The welding flange is not easy to deform, sealed well, the welding distance from the joint surface is large, the joint surface is free from welding temperature deformation, it takes a more complex cough body structure, suitable for pressure or temperature fluctuations of the pipeline or high temperature, high pressure and low temperature pipeline, generally used for PN greater than 2.5MPa pipe and valve connection; Also used to transport expensive, flammable, explosive medium pipeline. The butt welding flange is generally made by forging or forging process, which should be tested by ultrasonic wave without delamination defect.
Lap joint flange
flange connections, which are flange flange, two kinds of pipes, fittings, or devices, are first fixed in a flange flange, and between the two flanges, flange pads are bolted together to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, invisible flange connection. If you're in a boiler room or a production site, there are flanged pipes and equipment everywhere.
Socket flange
The full name of socket flange is socket welded steel pipe flange, which refers to the pipe end inserted into the flange ring ladder, welded at the pipe end and outside the flange. It comes with or without a neck. The flange with the neck tube has good rigidity, small welding deformation and good sealing. It can be used for the occasions of 1.0~10.0MPa pressure. Container B flange also belongs to socket welding flange, used for sealing requirements of higher occasions. Design, socket welding flange can be checked according to the whole flange. Socket flanges are only suitable for piping with nominal diameter of 50 or less.
