Its roots are in Torino, the fourth biggest Italian city in the North West of the country.
Nova Siria celebrates 80 years of history.
The S.I.R.I.A. Spa was founded in 1932.Its name means: “Società Idrotermica Razionale Industrie Affini”It specialized in the manufacture and installation of oil and gas combustion plants.
In 1980 the FERRERO family bought the company and changed its name into “NOVA” SIRIA Srl.
TodayToday NOVA SIRIA NOVA SIRIA is leader in large size and is leader in large size and taylor-made fittings in Italy and exports to 40 taylor-made fittings in Italy and exports to 40 Countries worldwide.Countries worldwide.
The company has ISO 9001/2008 certification The company has ISO 9001/2008 certification since 2003.since 2003.

All Nova Siria's couplings and fittings operate on the same basic compression principle:
As the bolts are tightened, the As the bolts are tightened, the two end rings are drawn two end rings are drawn togethertogether
This compresses the gaskets This compresses the gaskets against the pipe surface thus against the pipe surface thus providing an effective leak-proof providing an effective leak-proof seal.seal.
An alternative design is An alternative design is with separate bolts.with separate bolts.
This provides an This provides an independent tightening of independent tightening of the gaskets against the the gaskets against the pipe surface thus making pipe surface thus making the installation easier.the installation easier.

Our end restrained fittings (PIPE LOCKING SYSTEM) are used whenever the axial thrust of pressure has to be compensated.
The pipe locking fittings have been tested on all pipe surfaces and are tested for PN10 or PN16 according to size and pipe materials.
