PRK

Raccordi per tubi in plastica indicati per tubi in PE

Questo raccordo per tubi in plastica è compatibile con tubazioni in PE, SDR 11 e SDR 17, in materiale PE40, PE80, PE100 e PE100RC, e può essere utilizzato sia in applicazioni fuori terra che interrate. Presenta una serie di caratteristiche notevoli, tra cui dadi di serraggio in plastica acetilica stampata ad iniezione e stabilizzata con raggi UV. Resistente alla luce solare, assicura un funzionamento affidabile e senza problemi. Per semplificare la manutenzione, il raccordo PRK può essere smontato e riassemblato.

Features & Benefits

Comprehensive and flexible range

Ensures rapid installation.

No loose parts

A near-single unit construction allows for quick and easy installation.

AMETAL^®

Dezincification-resistant alloy that guarantees a longer coupling lifetime, and lowers the risk of leakage.

Technical Information

Technical description

Application:

Polyethylene piping, SDR 11 and SDR 17, of material PE40, PE80, PE100 and PE100RC according to EN 12201.
NOTE: Use TA's reinforcing bush (liner) for SDR 11 20-50 mm and for SDR 17 32-63 mm. See Accessories.

For PVC pipes with special thrust screw and cone, see Accessories.

PRK-coupling with FPL thrust nut for soft and hard copper pipes and soft steel pipes. A support bush must be used for soft copper and steel pipes. See catalogue leaflet FPL for complete details.

Dimensions:

16 to 63 mm
Special couplings not included in the standard range can be produced by means of reductions.

Max. working pressure:

Same as that appropriate for the piping.
(Coupling max 1.6 MPa = 16 bar).

Max. vacuum:

99% = 750 mm Hg

Temperature:

Max. working temperature: 40°C

Material:

Body: AMETAL® or gunmetal (allows underground installation).
Thrust screw: Acetal plastic
Thrust screw for dim 63, of AMETAL® with cone of Acetal plastic.

AMETAL® is the dezincification resistant alloy of IMI Hydronic Engineering.

Threads:

All bodies have pipe threads, which can be used as pipe connections.

Approvals:

Approved for tapwater systems by RISE Certification, Sweden.
(Not valid for sliding straight coupling 53 423-0xx).
