Astral Drainmaster Ringfit pipes are uPVC soil, waste and rain water (SWR) drainage pipes. Type B pipes are recommended for soil and waste discharge applications. Ringfit (push-fit): one end plain, other end self-socketed with an integral groove holding a yellow co-molded rubber ring; spigot is pushed into socket. Pipes are available in all sizes and in different lengths with single socket and double socket. Only products bearing the IS 13592 mark are certified.

Key features

• Made from virgin raw material
• tested for thickness and dimensional accuracy batch-wise and at random
• Extremely smooth bore and precision joints give high flow rates
• Chemical and corrosion resistant
• inert to most acids, alkalis, effluents, salts and aggressive soils
• UV stabilized for use in direct sunlight
• Non-conductor of electricity
• does not support combustion
• Light weight, resilient, with high impact resistance
• Reopenable joint - not fixed with solvent cement, so pipes/fittings can be realigned later
• Yellow co-molded rubber ring gives water-tight joint and allows for thermal expansion/contraction

Applications

• Type B: soil and waste discharge applications
• Houses, offices, hotels, commercial complexes, industries, hospitals
• Airports, railway stations, stadiums, theatres
