Factory Bend 5D API 5L Grade B / X52 ASME B16.49 Hot Induction Pipe Bend
We are a professional manufacturer of pipe fittings, flanges, and hot induction bends in China, supplying high-quality API 5L Grade B, X52, X60, X65, and X70 induction pipe bends for oil & gas, petrochemical, power generation, and pipeline projects worldwide.
Our ASME B16.49 hot induction bends are manufactured with strict dimensional control and excellent mechanical performance, suitable for high-pressure and large-diameter pipeline systems.
What is a Hot Induction Pipe Bend?
A hot induction bend is a pipe fitting manufactured by heating and bending steel pipe through induction heating technology. Compared with standard elbows, induction bends provide smoother flow transition, lower pressure drop, and better mechanical performance for long-distance pipelines.
Hot induction bends are widely used in:
- Oil and gas pipelines
- Petrochemical plants
- Power stations
- Offshore projects
- Water transmission systems
- LNG projects
ASME B16.49 Induction Bend Standard
Our induction bends are manufactured according to:
- ASME B16.49
- ASME B16.25
- API 5L
- MSS SP-75
The welding ends are prepared according to ASME B16.25 requirements.

FAQ
What is the difference between a pipe bend and an elbow?
Pipe bends usually have a larger radius such as 3D or 5D, providing smoother flow and lower pressure drop compared with elbows.
What does 5D pipe bend mean?
5D means the centerline radius of the bend equals 5 times the pipe diameter.
What standard covers induction bends?
ASME B16.49 is the main standard covering factory-made wrought steel induction bends.
Are custom bend angles available?
Yes. We can manufacture induction bends according to custom project drawings and specifications.
