Due to their self-recovery and micro-perforation free characteristics, the xFlex Speed ICTA series conduits are mandatory when making concrete buried systems. All the more so, they are also indicated when making chased systems, where the level of mechanical stress is lower.

No, pliable conduits must be chased, installed under plaster, floors, walls or ceilings, buried in concrete or liquid cement, on movable walls, or suspended ceilings. They can not be installed on outer surfaces.

No, rigid pipes and accessories can be installed outside the wall, but only in places which are sheltered from direct exposure to sunlight.

No, these conduits should always be stored in warehouses protected from sunlight. It is however possible to store pallets of conduits which are intact and covered by the specific anti-UV protective sheet. This protective sheet must always be replaced to protect the coils or bundles of conduits after picking products from the storage pallets.

The diameter of a conduit which undergoes laboratory tests with a load of 750 Newtons on 5 cm can reduce by up to 50%. Once the load has been released, the diameter returns to its original value with a decrease of less than 10%.

The IP Code (“Protection Rating”) consists of two digits (e.g. IP65) that define the degree of protection for the system in question. The term “system” refers to the coupling of pipes and fittings; the higher the figure, the higher the protection level. The first digit varies from 1 to 6 and defines the level of protection against solids (powder); the second is from 1 to 8 and defines the level of protection against liquids (water drops, splashing, immersion).

It is the lowest temperature to transport, store, install and use conduits. At temperatures no lower than the ones declared, conduits maintain their tested mechanical resistance to impact and compression.

In contrast with low temperature field, it is the highest temperature to transport, store, install and use conduits, without subjecting them to mechanical stress.

Conduit compression resistance decreases proportionally with increasing temperature. For installations in hot places and/or climates, it is fundamental to choose conduits with adequate mechanical and thermal features (ICTAAM 34323 – ICHW 33432 – ICTHX 43432). Polypropylene conduits are strictly recommended for their high mechanical and thermal resistance. In contrast, PVC conduits are not advised for their low thermal resistance, since they collapse over 60°C.

Unlike PVC conduits, polypropylene conduits are:
– 3 times more resistant to impact (6 joules at -5°C compared to 2 joules)
– resistant to low and high temperatures (from -15°C to +90°C)
– self-recovering
– free from micro-perforations
– environmentally friendly: they are LSZH, so with very low emission of toxic fumes, and they contain no heavy (e.g. lead) or chlorinated metals.
These characteristics make corrugated polypropylene conduits ideal for creating any type of system no matter what the conditions.
They are essential when implementing electrical systems buried in concrete, especially when castings undergo accelerated curing technologies using vibration systems.
