Viega Prestabo bend 90° 54 Steel/Galvanized 558253

Press connector systems with press connectors and pipes made of non-alloy steel 1.0308 (E235), in acc. with EN 10305-3, externally galvanised with a zinc layer thickness of 8–15 m (blue chromatised).Press connectorsAll sizes with SC-Contur – connections, which remain unpressed become visible when the system is filled. The SC-Contur is certified and fulfils the requirements of DVGW worksheet W 534, point 12.14, connectors with forced leakage.During leakage tests with water, Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of a dry leakage test with compressed air or noble gases from 22 hPa–0.3 MPa.MarkingRed symbol (to prevent confusion with Sanpress Inox (stainless steel) articles) »Not for drinking water installations«Sealing elementsEPDM, black (ethylene-propylene-dien-monomer rubber),not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine, petrol, FKM, dull blackDimensionsD38 (DN10), D12 (DN15), D34 (DN20), D1 (DN25), D114 (DN32), D112 (DN40), D2 (DN50), D212 (DN65), D3 (DN80), D4 (DN100)external-Ø 44,5 (DN32), external-Ø 57,0 (DN50)D=Pipe diameter in acc. with DIN EN 10255Areas of applicationClosed heating systemsClosed cooling and heating circuitsCompressed air systemIndustrial and plant engineeringFire extinguisher and sprinkler unitsSystems for technical gases (request required)Use of the system for application areas and media other than those described here must be agreed with Viega Service Center.Operating conditions•Operating temperature max. 110 °C (EPDM)•Operating temperature max. 140 °C (FKM)•Operating pressure max. 1.6 MPa (PN 16)NoteMegapress is suitable for•Fire extinguisher and sprinkler units (required minimum wall thickness and maximum wall thickness need to be considered)•For pipes in acc. with DIN EN 10220 / DIN EN 10216-1 / DIN EN 10217-1:raw line 1: D38–D4
