Pipes and Fittings
N. Sguassero is one of the most
experienced manufacturers of fiberglass pipe systems using "Dual Helical Filament
Winding" technology for the pipes and "Hand Lay-Up" system for the
fittings according to ASTM-UNI-AWWA standards; these technologies guarantee
a final product with superior mechanical characteristics
compared to other manufacturing techniques.
The possibility to "vary" the winding angle of the glass roving
(main component that guarantees the mechanical strength of the product) allows
N. Sguassero to produce pipes with the
most appropriate
modulus of elasticity, either axial or circumferential, requested for specific
applications (underground - continuous support - span support).
Piping is produced with an internal chemical barrier (liner) of a variable
thickness (from 1,5 to 2,5 mm and more upon request) and constructed with
materials that guarantee the best chemical resistance to the medium conveyed.
Whenever fiberglass (GRP-FRP) is not able to guarantee an optimum chemical
resistance, the internal liner of the piping is made of thermoplastic materials
(PVC-CPVC-PP-PE-PVDF) while the structural wall is made of fiberglass for
the mechanical resistance.
The standard range of diameters and lengths is the following:
ND 15/25 mm: 4-5 metre lengths;
ND 40/125 mm: 6 metre lengths;
ND 150/4.000 mm: 12 metre lengths.
Non standard lengths can be supplied on request.
Piping can withstand different load conditions (pressure, temperature etc.)
that depend on the raw materials used.
The types of resins available, as standard,
are the following:
- Ortophtalic;
- Isophtalic;
- Bisphenolic;
- Vinylester.
A wide range of different resins for specific applications may be used with
our production technology.
Piping is supplied with the following types of joints (special joints may
be studied and / or supplied upon request):
- Plan ends for Butt & Strap joints (lamination/bonding);
- Bell & Spigot with double "O" Ring and keylock system
for easy installation on site without the aid of specialized personnel;
- Sleeve Coupling with double"O" Ring and keylock for easy installation
and disassembly on site without removing the pipes themselves and without
the aid of specialized personnel;
- Conical glued/adhesive joint for quick on site installation;
- Special Plain Ends for "mechanical couplings" such as Helden,
Straub -Reka or similar;
- Flanges, either fixed or loose (with backing ring) in the required material
and drilling standard (UNI – ANSI – DIN etc.).
Moreover N. Sguassero
produces piping in spool pieces (prefabricated - factory made) constructed
on the basis of Customer's drawings, that are ready for installation on site
without the aid of specialized personnel. |
