3D Bend
3D bend is a special pipe fitting, which is characterized by its bending radius is three times the nominal diameter of the connected pipe. This design is called a large radius elbow, also known as a butt-weld elbow. Due to its large bending radius, it can effectively reduce the stress concentration of the pipeline when turning, thereby improving the durability and service life of the pipeline.

3D Bend Description
3D bend is a piping system in the axial bending radius of the pipe nominal diameter of 3 times the connectors, alias 3 times butt-welding elbow, belongs to the category of industrial fittings, mainly used in electric power, chemical industry, petroleum and other fields of low-pressure piping system. Its bending radius between the long radius elbow (1.5 times the diameter) and short radius elbow (1 times the diameter), the core function is to change the direction of the pipe

Advantages
- Low flow resistance design: Larger bending radius reduces turbulence, and the pressure loss is more than 30% lower than that of short radius elbows, which is suitable for high flow rate systems (such as oil pipelines).
- High structural strength: The hot simmering process improves the creep resistance of the metal, and the pressure resistance is ≥10MPa (carbon steel material).
- Space adaptability: Balance turning efficiency and installation space, widely used in equipment-intensive areas (such as around chemical plant reactors).
Applications
- Energy and chemical industry
Oil/gas pipeline steering, resistant to corrosion by sulfur-containing media (stainless steel 316L material).
- Power and shipbuilding
Boiler high-temperature steam pipeline (chrome-molybdenum steel material resistant to 650℃), compact layout of ship engine compartment.
- High-end manufacturing
Aerospace hydraulic pipeline (titanium alloy 3D elbow), automobile exhaust system.
