Manufacturer of High Pressure Pipe Fittings Manufacturing, Industrial Heavy-duty Pipe Fittings
Pipe Fittings by Process
Advanced pipe fittings manufacturing processes are essential for the reliable finished product quality. NFF has over 30 years of experience in pipe fittings production and has over 160 manufacturing equipment, which allow us to perform every process and control pipe fittings quality with reduced overall production cost. According to the size, installation type and material, each pipe fitting is manufactured by its own process - welding, cold forming, hot forming, hot extrusion, forging or machining.
-
- Welded Pipe Fittings
Welding process is a good choice for the production of oversize pipe fittings. For example, if you want an elbow larger than DN600, it's rather difficult to make it by a seamless steel pipe. Generally, we take two steel plates to weld a large size elbow.
-
- Seamless Pipe Fittings
For the production of regular-size pipe fittings, seamless steel pipe is a perfect raw material. Each pipe fitting is manufactured with its best appropriate process—cold forming, hot forming or hot extrusion, which is be decided with considerations of its material, size, shape, use, standard and special properties.
-
- Forged Pipe Fittings
Forged pipe fittings are made by steel bars or ingots undergone heating, forging and machining. Forged pipe fittings usually connect to pipelines by socket weld or thread. They are mainly used for small bore piping system.
