PREMANT district heating pipe
Drainer
Description
The end cap on the vent branch has to be ordered separately. Drainers are pre-insulated in the factory in the same way as
the plastic casing pipe, and they conform to EN 448. The branch is made with a T-piece to EN 10253 and welded-on pipe
cylinders, or by extruding the base pipe.
The nozzle height (h) and the nominal width can also be produced to the customer's requirements. Flanges, relief valves
and ball valves can also be used as closures for the nozzle.
