This appraisal considers Victaulic ductile iron restrained mechanical couplings manufactured in compliance with EN 12842:2012 Ductile iron fittings for PVC-U or PE piping systems-Requirements and test methods. The couplings are suitable for joining PN16 PE80 or PE 100 pipes manufactured to AS/NZS 4130.

Victaulic literature nominates that the couplings are suitable for joining PE pipe with SDR’s ranging from 7 to 21, however the type tests submitted for this appraisal were conducted on PN16 PE100 pipes (SDR 11) at test pressures to qualify a PN16 rating for the coupling. This appraisal’s recommendation is therefore limited for pressure applications up to 1600kPa when utilised on PN16 PE80 or PE100 pipe.

Two types of couplings have been submitted for appraisal:

  • Style 905 Victaulic couplings for joining plain end PE pipe in sizes from DN 63 to DN 225.

This coupling style incorporates a sealing gasket and Grade 316 stainless-steel retaining rings, integral to the coupling housing, to provide joint restraint. The couplings have been type tested on PN16 PE100 pipe at test pressures that qualifies allowable operating pressures up to 1600kPa. No special preparation is required for the plain ends of the pipe.

  • Style 907 Victaulic couplings for joining plain end PE pipe to grooved end IPS steel pipe in sizes from DN 63 to DN 225.

This coupling style incorporates a transition gasket to accommodate sealing on both plain end PE pipe and grooved end IPS steel pipe. Grade 316 stainless steel retaining rings, integral to the coupling housing, provides joint restraint for the PE pipe. The steel pipe must be grooved prior to installation of the coupling. The couplings have been type tested on PN16 PE100 pipe at test pressures that qualifies allowable operating pressures up 1600kPa.
