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.

PE FLANGER COVER

BRIEF DESCRIPTION

Flanged cover made of high density polyethylene (HDPE), which consists of a flange welded on a cylindrical element made of HDPE (as the top of inspections or pipes) + closing blind flange, and a specific EPDM sealing gasket is placed between the two flanges. Both flanges are provided with matching holes (D= 18 mm) for the connection through screws (M16 x 70 mm) and corresponding bolts, for inspection accesses with a guarantee on gas and liquid tightness without pressure.

MAIN FEATURES

Made entirely of PE (except for the locking screws)
Stainless steel screws on demand
High chemical resistance
Completely  tight
Lightweight and quick to install
Inert to stray currents
Recyclable

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 8slowflow (2)
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
