Seamless Steel Elbows Bw DIN2605-1
TECHNICAL DESCRIPTION
Elbows are connecting elements with a specific bending radius that are used to connect pipes of the same diameter.
Knee bending radius:
• short radius 2D
• normal radius 3D
• long radius 5D
The elbows can be made 45°, 90°, 180°.
Dimensions: Ø 21.3 – 711.0
Our SEAMLESS STEEL ELBOWS BW DIN2605-1 are precision-engineered pipe fittings designed for high-pressure and high-temperature industrial applications.
