For sewage discharge from small diameter pipes
The TOPAZ ductile iron pipeline system is dedicated to sewage discharge for small diameters of DN/OD 75 to 160 mm and is suitable for most soils.
The range comprises six metre pipes along with many fittings and accessories.
Benefits
Protection: resulting from research by Saint-Gobain PAM, BioZinalium ensures the perfect external protection for TOPAZ pipes. Composed of 85-15 zinc-aluminium alloy enriched with copper and covered by a protective layer of Aquacoat. BioZinalium reduces the risk of localised biocorrosion. TOPAZ fittings are protected internally and externally with a red epoxy coating applied by powdering with a minimum thickness of 250 µm.
Resistance: DUCTAN, a completely smooth internal lining provides TOPAZ pipes with a strong resistance to the harshest acid and alkaline effluents over a pH range from one to 10. The plasticity of DUCTAN ensures good impact and abrasion resistance.
Simple installation and adaptability: designed to be handled and installed by hand, TOPAZ products are easy to fit and can adapt to ground movements.
Economic laying: the design of TOPAZ pipes enables eco-laying with the reuse of natural backfill and thus creates considerable cost savings in relation to the purchase and transport of raw materials.
Compliance: TOPAZ high performance elastomer NBR quality joints have been adapted to resist the effluent found in mains drainage, complying with the requirements of standard EN 681-1 type WG.
