HYDROLINE C is a centrifugally spun cement mortar lining made up of Type SR Blast Furnace Slag cement, sand and water. Pipes are spun with high radial acceleration, around 100g and are simultaneously vibrated, producing a very dense smooth lining of extremely low permeability. From years of proven in service experience, HYDROLINE C is hydraulically smooth with Colebrook- White k factors for all new pipes commonly in the order of 0.01-0.03mm.
HYDROLINE CSC -Some very aggressive, soft waters of low hardness (total alkalinity <30mg/L) or high dissolved C02 may leach lime from cement mortar linings and result in an increase in pH of the conveyed waters. This is particularly so with low flows or long residence times, say in the order of 1-3 days. This problem can be easily overcome at the design stage with an assessment of water chemistry and operational conditions.
The application of an effective seal coat to the cement mortar lining surface will restrict pH increases in the conveyant.
HYDROLINE CA features the same high application specifications of our premier lining product, though this time centrifugally cast with a special calcium aluminate cement mortar, which is ideally suited to aggressive applications such as septic gravity sewers and other aggressive industrial effluents.
HYROLINE PUR is a sand coloured Polyurethane lining applied at an average of 1.5mm thick internal layer. The lining offers excellent resistance to chemical and attack (pH1-13) and abrasive media. The lining also strong - with an elongation strength >10% and adherence >8MPa - it will not detach even in the most severe conditions.
