Hydroscandi lõikurrõngasliitmikud

Cutting ring fittings are characterised by a very rigid tube assembling, resistance to vibrations and pressure impulses. The fittings can be dismantled/reassembled more than once.

When assembling the cutting ring fitting, the ring's two edges are pressed into the pipe, which gives a mechanical bearing. The first edge has already started the penetration before the second edge starts cutting into the pipe. After the assembling, part three of the cutting ring is pushed in between the cone and the pipe, to make sure no vibrations are transported to the cutting edges. The fourth part secures radial movement. The design of the ring profile gives a very strong, axial and radial bearing. The tension is carried by the whole cutting ring length.

Materjalid
Hydroscand's cutting ring fittings are manufactured of automatic steel or of forged materials. The standard surface treatment is E-coated. E-coated is the name of the surface treatment Hydroscand use for its fittings. It is Cr6 free and therefore more environmentally friendly and better for human health. Temperatures up to +200°C. Sealing with standard NBR maximum +90°C.

Ühendused
Withworth pipe thread G, cone pipe threads R, NPTF cone, UNF, metric. Cutting ring cone according to ISO 8434-1. When different connection dimensions are possible, the standard dimension is noted in bold text.
 

Sertifikaadid
Hydroscand can deliver fittings with the following standards/certificates: DVGW, Norske Veritas, Germanischer Lloyd, ISO 9002. 

Please note that all cutting ring fittings are also available without nut and cutting ring.
