The S.I.R.I.A. S.p.A. companywas founded in 1932. It wasspecialized in theconstruction of waterpipelines and aqueducts ingeneral. In 1980 theFERRERO family bought thecompany and changed itsname into NOVA (new) SIRIAS.r.l. and specialized in theproduction of fittings. In2012 the Companycelebrated 80 years ofhistory.

Historical Context

Today Nova Siria relies on:• 2 plants• 40 employees• 15 distributors• Customers in more than 50countries worldwide.

The Company

Roletto (TO)ITALY

Wide Range Mechanical Couplings

Centre Sleeve

Compression Rings

Sealing Gaskets

Bolts

As the bolts are tightened, the two end rings are drawn together.This compresses the gaskets against the pipe surface thus providingan effective leak-proof sealing.

Tolerance Range

Range of different outside diameters that a single fitting can connect.

Our products are coated withRILSAN®NYLON 11, a polymer producedfrom a renewable raw material of plantorigin, the Ricinus Communis (Castor Oil),which grows primarily in tropical countries.

Rilsan® Fine Powders is hence athermoplastic which is not directly impactedby the variation in crude oil prices.

Rilsan is compliant with the most importantinternational norms regarding contact withpotable water (e.g. WRAS, DWGW, etc.).

Anti Corrosion Coating

Straight couplings provide a flexible mechanical connection between two spigot ends

having the same nominal bore and the same or different outside diameter.

Reducing Couplings

When the difference between the O.D. of the pipes is bigger than the gasket’s tolerancerange (30mm or 50 mm) the solution is our stepped couplings.

Reducing Couplings

Wide Range Flanged Adaptors

Our flanged adaptors are used to joint pipes of any material with any flanged component(e.g. valves)

Ductile Iron Style (OD 58 – 327 mm.) Carbon Steel Style (OD 327+ mm.)

“Pipe Locking” is our end restrained system made of radial grippers.It is independent from the sealing system and works on the majority of pipe materials(HDPE, DUCTILE IRON, STEEL etc.).Pipe Locking System is provided on every end restrained fitting from OD 58mm. to OD 2000+mm.

MULTIGRIP are our endrestrained fittings and areused whenever the axial thrustof pressure has to becompensated.

MULTIGRIP steel fittings havebeen tested for PN10, PN16 orPN25 according to size andpipe materials.

Duofit fittings are used to repair and hottapping live pipelines. They are designedand produced on demand.

Duofit provide a permanent, fast andinexpensive solution to all repair and hottapping problems.

First Duofit installation ever (1993)

Live pipelines do not have to be shut off

No mains emptying

No pipe cutting
