Threaded Flange Nickel Alloy Steel Flange N08825 RF ANSI B16.5 900#
Threaded flange refers to a kind of flange that uses a thread to connect with a pipe. When designing,
it can be treated according to the loose flange. The advantage is that no welding is required, and the
additional torque generated on the cylinder or pipe when the flange is deformed is very small. The
disadvantage is that the flange thickness is large and the cost is higher. Suitable for connection of
high-pressure pipes.
Implementation principle
Threaded flange is a non-welded flange that processes the inner hole of the flange into a pipe thread
and connects with the threaded pipe. Compared with flat welding flanges or butt welding flanges,
threaded flanges have the characteristics of convenient installation and maintenance, and can be
used on pipelines that are not allowed to be welded on some sites. The alloy steel flange has
sufficient strength, but it is not easy to weld, or the welding performance is not good, you can
also choose the threaded flange. However, under the condition that the temperature of the pipeline
changes sharply or the temperature is higher than 260 ° C and lower than -45 ° C, it is recommended
not to use the threaded flange to avoid leakage.

Weld Neck Flanges
Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications.
They have a long tapered hub and are often used for high pressure applications.
We are a fast growing organization, engaged in manufacturing, supply and export of welding neck
flanges, industrial weld neck flanges and forged flanges. Our weld neck flanges are drilled with the
wall thickness of flange having the same dimensions of pipe. Flanges for heavier pipes have smaller
bore, while flanges of lighter pipes have larger bore. These weld neck flanges, industrial weld neck
flanges, forged flanges are normally used for high-pressure, cold or hot temperature.
