Manufacturer of High Pressure Pipe Fittings Manufacturing, Industrial Heavy-duty Pipe Fittings
Industrial Pipe Fittings
In petroleum, chemical and power generation industries, pressure piping is an essential tool to transport liquid or gas in severe working environments. NFF can offer butt weld pipe fittings, socket weld pipe fittings, thread pipe fittings and pipe flanges for these pressure pipes, which are resistant against high temperature, high pressure and corrosion.
A long-term and large-scale piping project needs quality pipe fittings from an experienced and reliable supplier. NFF has dedicated to the manufacturing of high-pressure pipe fittings from 1991 and has strong production strengths—over 160 manufacturing equipment and over 700 sets of molds. We have successfully supplied large quantities of industrial pipe fittings for power plants, oil and natural gas transportation projects, marine drilling platforms, mines, papermaking factories and various industrial applications. NFF is a long-term supplier of many world-renowned companies like Shell, Kuwait and Fluor. We are proud of our production capabilities to provide you any pipe fitting you need with exceptional quality and on-time delivery.
All of our industrial pipe fittings are designed and manufactured in strict accordance with industry standards:

-
- Butt Weld Pipe Fittings
Butt weld pipe fittings are available as elbows, tees, crosses, reducers and other fittings, which are widely used in heavy-duty industrial piping applications with high pressure requirements, especially suitable for super-large pipelines. These butt weld fittings have beveled ends, allowing for easy weld connection with pipe bevels.
-
- Socket Weld Pipe Fittings
Socket weld (SW) pipe fittings have plain spigot ends, allowing for being directly inserted into a recessed area of pipes or flanges to make a tight connection. Socket welded joint construction provides benefits of zero leakage and high structural strength. Compared to butt weld fittings, socket weld fittings feature more compact design...
-
- Threaded Pipe Fittings
Threaded pipe fittings are produced by tapping inside or outside threads onto the parts after forming. Threaded pipe fittings are connected to the pipe ends which have threads and they are commonly used for small-bore pipelines like water, oil, gas and low-pressure steam pipeline. Threaded fittings feature easy installation and allow for frequent dismounting.

- Heavy Duty Pipe Fittings
The plumbing system in heavy-duty applications requires higher resistance against pressure and corrosion than common plumbing. Therefore, pipe fittings for heavy duty industries need to be customized to meet the application requirements. NFF is able to provide customized heavy duty pipe fittings for high-pressure steam pipeline in power plants ...
-
- Industrial Pipe Flanges
Flange is one kind of common pipe fittings, which allows to be dismounted after installation, greatly increasing the maintenance flexibility of the piping system. Hence, flanges are essential to a piping system requiring regular maintenance. NFF can provide a wide range of industrial pipe flanges, including slip-on (SO) flange, weld neck (WN) flange ...
