Type of Flange
Raised Face Weld Neck Flange
Raised face weld neck flange is an industrial product characterized by the requirement that the joint surface of both flanges on the sealing surface be convex.
Flat Face Slip On Flange
Flat face slip on flange refers to a type of flange that is connected to a container or pipeline using fillet welds. There are two types of flange rings: those with necks and those without necks.
High Hub Blind Flange
High hub blind flange is a type of flange used in pipeline systems to completely seal the ends of pipelines. It does not have a central hole and is mainly used for isolating, sealing, or temporarily sealing pipeline systems.
Raised Face Socket Weld Flange
Raised face socket weld flange refers to a flange that is inserted into the flange ring ladder at the end of the pipe and welded on the outside of the pipe. There are two types: with neck and without neck.
Pipe Threaded Flange
Pipe threaded flange is a method of connecting pipes with threads by machining the inner hole of the flange into pipe threads and matching them with threaded pipes to form a non welded flange connection.
Long Weld Neck Flange
Long weld neck flange is a type of flange with a higher neck height, which improves the stiffness and load-bearing capacity of the flange. However, its on-site installation is relatively convenient and can omit the process of welding and rubbing, making it popular in practice.
Grooved Flange Adaptor
Grooved flange adaptor is a pipeline connection method mainly used for connecting large-diameter pipelines. It is achieved through clamp connection technology and has the characteristics of simple operation and quick installation.
Steel Plate Flange
Steel plate flange is a mechanical connection component composed of flange, sealing gasket, and bolts, which is used to tightly connect two adjacent pipelines or equipment together.
Advantages of Flange
Reliability
The flange adopts the principle of face sealing, and the connection is strong, which can ensure the safe and reliable operation of the fluid conveying system.
Economic efficiency
The manufacturing cost of the flange is relatively low, and it is easy to assemble by fixing methods such as screws or nuts, which can improve production efficiency and reduce production costs.
Strong pressure bearing capacity
The flange connection consists of multiple bolts and gaskets, which can withstand high pressure and tension.
Good sealing
Flange connection is formed by placing the flange gaskets at both ends of the pipeline between the flanges and tightening the bolts.
When installing flanges, it is essential to measure the flange and its surrounding components accurately. This will ensure that the flange fits securely onto pipes or other equipment and helps prevent leaks from occurring due to improper alignment.
Flanges should be inspected for any signs of damage such as cracks or corrosion before installation in order to ensure that they are still safe and suitable for use. If a flange needs to be machined or modified then this should also be done prior to installation.
Finally, all bolts used with the flange should be checked for tightness and lubricated if necessary in order to make sure that they are properly secured when tightened during installation.
