HEGLERFLEX-SHK

Flexible plastic jacket pipes of PE for sanitary and heating engineering

Application

The HEGLERFLEX-SHK jacket pipe is a flexible protective tube used with pipelines for heating and sanitary engineering inside buildings.

The stability requirements for protective tubes, specifying an adequate deformation resistance during construction and in the installed condition, are complied with. When used as a protective pipe in a heating system, permanent resistance up to an inlet temperature of 60 °C is ensured. The jacket pipes are available in two different qualities and in customer-tailored design (to KIWA BRL-K 536
Part D or KOMO BRL 5607, and SINTEF directive
No.02-2014/1^st edition).

PE corrugated pipe, outside and inside corrugated
Admissible temperature range, without mechanical load:
