Slow Flow – PE corrugated pipes for high slopes networks

BRIEF DESCRIPTION

Double wall corrugated pipes made of high density polyethylene (HDPE), with a corrugated outer surface and provided with artificial macro roughness (AMR) in the inner surface. Pipes are available in black colour, with a diameters range (DN/OD) that goes from 200 up to 500 mm. They are delivered in bars and are used for the construction of drainage systems laid at a high slope on which it is necessary to slow down the flow speed of fluids. The hydraulic behaviour was tested at a qualified test laboratory of a university engineering faculty in Italy.

MAIN FEATURES

Ring stiffness: SN 8
Corrugated outer wall and wavy inner surface
Ability to slow down the speed of water up to slopes of 20%
Reduction of height and number of drop manholes
Socket or coupling connections with sealing gasket
Pipes can be connected with the CorPress joint
Lightweight and easy to install
High chemical and abrasion resistance
Inert to stray currents
Recyclable

SGK – HDPE big size spiral pipes for non-pressure networks

BRIEF DESCRIPTION

HDPE structured wall pipes made through spiral winding technology which find application in non-pressure underground sewerage and drainage systems and road embankments crossing. They consists of a smooth inner surface for water flowing and an outer one (in different shapes and sizes) made of PP and PE that determines the ring stiffness, with or without an external flat PE surface. All pipe lengths are provided with an integrated junction socket and the respective spigot for the electrofusion or with grooves for the sealing gasket junction system. The diameters range (DN/ID) goes from 800 up to 2500 mm.

Ring stiffness:

The two classifications of the ring stiffness according to the two distinct standards are not correlated, as they are data obtained through tests with different methods and times.

MAIN FEATURES

Wide range of diameters
Smooth or profiled outer surface
Wide range of structured profiles (moment of inertia) – ring stiffness
Socket connections with the electrofusion technology or with sealing gasket
High reliability of connections tightness
Lightweight and easy to install
High chemical and abrasion resistance
Inert to stray currents

PE100 – RC type 2 pipe for water “Europas Safe10”

BRIEF DESCRIPTION

Solid wall pipes made of PE 100 RC (MRS 10 MPa – σ_S 6,3 MPa) with a smooth inner and outer surface and with high resistance to Slow Crack Growth (SCG).
Type 2 (2 layers) is available with inner black colour wall (90% of the thickness) + outer blue colour wall (10% of the thickness).
Diameters (OD) go from 20 up to 450 mm. Pipes can be provided in coils or bars.

MAIN FEATURES

High resistance to SCG from point loads and surface incisions
Particularly recommended for NO DIG installation techniques
Good bending properties
100% permanent water tightness
Helpful for the detection of external incisions greater than 10%
Plastic behavior in unstable circumstances
Wide range of diameters and pressure classes (sizing optimization)
Wide range of fittings and special pieces , standard and customized
Related to aqueducts, this pipe is in conformity with the EN 1622 standard “determination of threshold of smell and taste”
Inert to stray currents
High chemical resistance (ISO/TR 10358)
High abrasion resistance
High shock absorbing capacity
Recyclable

Plug&Play – coupler/socket for PE pressure pipes

BRIEF DESCRIPTION

Push-to-connect double coupler made of polypropylene (PP) for PE pipes up to PN16, provided with double lip sealing gaskets and special anti-slipping rings. Elbow and tee shapes are available too. The diameters range (DN) goes from 20 up to 250 mm (OD pipes), but is also possible to request reduced sizes. The range for PE100 PN16 pipes from ɸ 20 to 63 mm requires the adoption of a “pipe liner” inside the end of the pipe to be connected. The socket version is made of PE from DN 90 up to 250 mm (PN 16-10), then butt-welded on one end of the pipe in the factory before the shipment (on-site welding is possible too).

MAIN FEATURES

High tightness reliability
Easy and fast to install
Wide range of diameters
Inert to stray currents
High chemical resistance (ISO/TR 10358)
High shock absorption capacity
Recyclable

NO FIRE – Fire and environmental protection system in the tunnels

BRIEF DESCRIPTION

NO FIRE is the system implemented in the collection of liquids that could be found on the road surfaces of tunnels.
It has a dual purpose: protects the environment from accidental spilled liquids and reduces the potential fire spread  through the manifold.
The system consists of several units: NO FIRE storm drains made of two siphons (with a drain grid D400 load class) + standard PP corrugated pipes (other can be used on request) + water treatment system.
The NO FIRE system was designed and developed to satisfy all safety standards (in terms of personal and environment) requested by recent road tunnels, the planned ones and the ones that will be upgraded.

MAIN FEATURES & BENEFITS

Safe and tested system;
In conformity with the security standards requested by TERN networks;
Multiple sizes available, for pipes with DN/OD 250-315-400 mm and DN/OD 300-400 mm;
Gravity system (no electromechanical devices);
Environmental safety  in case of fire (no fire and smokes spread in the manifold);
Surface drainage channel: 500 x 270 mm;
Lightweight and ease of installation;
Durability: a cement mortar coating guarantees the functioning of the system in case of fire too;
High chemical and abrasion resistance;
Inert to stray currents;
Excellent benefit-cost ratio;
Full technical support by the U. T. System Group.
