Haustherm Heliroma HELISYSTEM PP-R 100 SDR 7.4 Pipe
The Haustherm Heliroma HELISYSTEM PP-R 100 SDR 7.4 Pipe is a single-layer pressure pipe for plumbing installations. Its raw material is grade PP-R 100; its minimum required strength (MRS), determined according to ISO 9080, is 10.0 MPa.
Inner surface roughness is around 0.007 mm, so it does not hold scale or deposits and the bore does not narrow over time. It does not corrode, and welded joints form a gasket-free, leak-tight line — safe to use concealed in walls and in screed.
