PREMANT district heating pipe

Fitting bend

PRE 6.354

Fitting bends are used as additional insulation for medium pipe bends welded in at the building site

by the pipelayer. Fitting bends are made from non-shrinking HDPE pipe. Shrink-on collars are used

to seal the pipe on the face side.

The

fitting bend comprises:

• Segment bend made from PE sleeve pipe

• Shrink-on collars

Fitting bends are made to measure depending on the bend design (radius, angle, length).

The following details are therefore required when placing an order:

• Nominal diameter of the medium pipe

• Nominal diameter of the PE casing

• Bend design or radius

• Angle of the fitting bend

Compliance with the minimum lengths defined in the following table is required if a prefabricated

welded bend as per EN 10253/2 is

fitted between the adjacent free pipe rod ends.
