Preinsulated bends comply with the requirements in EN 448-1 and can be used for a max. operating pressure of 25 bar up to and including DN400. Larger dimension are as a standard for max. operating pressure of 16 bar. However, on request they are available for an operating pressure of 25 bar.
90° bends in dimensions ≤ ø 406.4 mm have a bending radius of 2.5 x d and are made by means of cold bending.
90° bends in dimensions ≥ ø 457.0 mm have a bending radius of 1.5 x d and are made by means of a weld elbow.
Preinsulated bend with same leg lengths.
On request available in major dimensions.
