Common Flange Types
To provide you with various types of pipe flanges of different specifications and materials
Weld Neck Flanges
These flanges have a long, tapered hub that attaches to the pipe. They are employed in high-pressure and high-temperature applications because they provide adequate reinforcing and strength.
Slip-on Flanges
These flanges glide over the pipe and are then welded into place. They are simple to install, inexpensive, and commonly used in low-pressure applications.
Blind Flanges
Solid discs are used to seal the end of a pipe or vessel. They are commonly employed in systems that require regular closure or testing.
Socket Weld Flanges
These flanges feature a socket or bore into which the pipe is placed and then fillet welded. They are appropriate for smaller-diameter pipelines and high-pressure applications.
Lap joint flange
It’s like Slip-On Flanges, but the flange surface and hole of a lap joint flange are rounded at the corners to fit the flange portion of a lap joint stub end. This means that it can only be used with a lap joint stub end.
Threaded Flanges
Threaded flanges have internal threads that connect to pipes with exterior threads. They are frequently employed in low-pressure applications and non-critical systems.
We can also make custom flanges for you
Due to the special projects of some customers, standard flanges cannot achieve the use effect, so we can also provide customized flanges as required.
The process is as follows:
