Underground drainage

PVC pipes threaded and micro-slotted for drainage

PVC pipes, made by System Group PVC, have the double function of collecting excess water in the soil and conveying it in a drain line,in order to ensure the safety of environments in the vicinity of natural or artificial slopes. It has been proven for years, that the use of a product with the slots adequately adjusted to the ground particle size, guarantees a long draining effectiveness over time. The sub-horizontal drainage pipes can also be used for road drains, agricultural, railway, airport, construction and public green.

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

CENTRALDRENI HDPE solid wall slotted pipes for drainage

BRIEF DESCRIPTION

Solid wall pipes made of high density polyethylene (HDPE) with a smooth inner and outer surface, available in black colour. They are provided with transverse slots of different sizes and layout and are used for the construction of underground drainage systems for liquids, landfill leachate and biogas collection. The diameters (OD) range goes from 75 up to 400 mm and pipes are delivered in bars. Upon request, they can be certified PSV (Plastica Seconda Vita – Second Life Plastic) when are made with HDPE obtained from separate waste collection to guarantee that the products can be traced back so being part of circular economy model.

MAIN FEATURES

Wide range of slots layout
Long-range bending
Plastic behaviour in unstable situations
Wide range of fittings and special pieces, standard and customized
Inert to stray currents
High abrasion and chemical resistance (ISO/TR 10358)
High shock absorption capacity
Recyclable
