PREMANT district heating pipe

Pipe routing

Pipe routing for PREMANT district heating pipe is not subject to any special requirements. In relation to the pipe, it

should mainly be selected on the basis of expansion capability. In normal pipe routing, changes of direction using

L-bends are the first choice for this purpose. Then come Z-bends and U-bends, which accommodate the expansion that

occurs at precisely defined points.

The angular dimensions of the 'expansion bend' should not exceed 90°, otherwise substantially longer expansion limbs

are needed; whenever possible, right-angled pipe routing should be the aim.

If no expansion can be accommodated in buildings,

fixed points must be positioned in the building wall

or approx. 3 m in front of it.
