PVC solid wall pipes for cable protection

BRIEF DESCRIPTION

Solid wall pipes made of polyvinyl chloride (PVC-U), available in grey colour (RAL 7021). The diameters range (OD) goes from 50 up to 250 mm. Standard pipes are delivered in 6m lengths with a built-in socket provided with a gasket. Glue connection available on demand. They are used for the construction of underground networks for cables threading.

For Circular Economy goals, pipes can be partially made (on demand) with recycled material, guaranteed by PSV mark (Plastica Seconda Vita – Second Life Plastic).

MAIN FEATURES

Ring stiffness: 450 – 750 N
Impact resistance class: L – N
CEI EN 61386 standard (with IMQ quality mark)
Standard socket connections with sealing lip-gasket made of EPDM (EN 681)
Glue socket connections
High chemical and abrasion resistance
Inert to stray currents
It can be provided with PIPE TRACER, the 3D (altimetric map) tracking system for underground pipelines.

SGPVC Pressure – PVC solid wall pipes for water pressure networks

BRIEF DESCRIPTION

Solid wall pipes made of polyvinyl chloride (PVC-U), available in grey colour (RAL 7021). The diameters range (OD) goes from 50 up to 500 mm. Standard pipes are delivered in 6m lengths with a built-in socket provided with a gasket. Glue connection available on demand. They are used for the construction of pressurized piping systems (irrigation – water system – plant engineering and other industrial applications).

It can be provided with PIPE TRACER , the 3D (altimetric map) tracking system for underground pipelines.

SG-PVC Sewer – PVC solid wall pipes for sewerage networks

BRIEF DESCRIPTION

Solid wall pipes made of polyvinyl chloride (U/D-PVC), available in brick-red colour (RAL 8023). The diameters range (OD) goes from 110 up to 500 mm. Standard pipes are delivered in 3 or 6m lengths with a built-in socket provided with a gasket. Glue connection available on demand. They are used for the construction of non-pressurized waste systems, outside the buildings (code: “U”), buried inside the building (code: “D”).

For Circular Economy goals, pipes can be partially made (on demand) with recycled material, guaranteed by PSV mark (Plastica Seconda Vita – Second Life Plastic).

MAIN FEATURES

Ring stiffness: SN 2 – 4 – 8
“ICE” certification (impact resistance test at -10°C for installation in cold climates) with marking☸

On demand:
– Socket connections with DINLOCK gasket type (with hard insert made of PP). Cold insertion (EN 681)
– Socket connections with POWERLOCK gasket type (with hard insert made of PP). Warm insertion (EN 681)
– Glue socket connections

PSV mark (Plastica Seconda Vita – Second Life Plastic) on demand)
High chemical and abrasion resistance
Inert to stray currents
It can be provided with PIPE TRACER , the 3D (altimetric map) tracking system for underground pipelines.
Wide range of standard moulded fittings

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.
