Threaded Fittings
Manufacturing technique
Yuanyang provides a wide range of threaded fittings and pipe fittings, offering the possibility for users to choose the correct fitting basing on the applications. Threaded fittings are manufactured exclusively with die forging and machining techniques. Welding or casting treatments are unacceptable.
| Type | Nominal diameter | Pressure range | |
| 45/90 degree forged elbow | 1/2"~4" | DN15-DN100 | SCH80, SCH160 CL2000~CL6000 |
| Forged reducer | 1/2"~12" | DN15-DN300 | SCH40~SCH160 |
| Forged tee, cross, cap | 1/2"~4" | DN15-DN100 | SCH40~SCH160 |
Quality Commitment
At Yuanyang, quality and customer needs are given high priority. We purchase raw steel materials only from well-known brands. In our factory, each production step is under strict control and supervision; and raw materials are marked with different colors so that they are easily-distinguished; 100% spectral detection is conducted for all of the finished fittings before shipping.
