    Ringfit pipes feature a socket with an internal groove designed to hold a rubber ring, ensuring a secure, watertight joint that accommodates thermal expansion and contraction. In contrast, Selfit pipes are socketed using an automatic socketing machine without a groove and are joined with solvent cement, which creates a strong, permanent and leak-proof connection. Both options provide reliable solutions for drainage pipes and fittings systems.

    Selfit pipes come with one plain end and one self-socketed end, which allows for easy and secure installation. These pipes are joined using solvent cement, which forms a strong, permanent and watertight bond. The plain end of one pipe fits into the self-socketed end of another, with solvent cement ensuring a seamless connection. Ideal for drainage and sewerage pipes and both aboveground and underground drainage pipe systems, Selfit pipes offer durability and reliability in various applications.

    Yes, both Ringfit and Selfit pipes are designed to ensure watertight joints for a secure and leak-proof plumbing system. Ringfit pipes use a specially designed rubber ring that forms a tight seal, preventing water leakage. On the other hand, Selfit pipes create a permanent watertight bond using solvent cement. These advanced jointing solutions make drainage pipes and fittings installations more efficient and reliable. Whether for PVC pipe fittings or sewer pipe connections, Astral Pipes delivers long-lasting and high-performance solutions.

    A lightweight uPVC drainage pipe is a durable and easy-to-handle pipe used for efficient water flow in drainage systems. Made from UPVC, these pipes are strong, rust-free and long-lasting. They are commonly used in drainage pipes and fittings, sewerage pipes, aboveground and underground drainage pipe and other plumbing applications. uPVC pipes are lightweight, which makes them easy to transport and install while ensuring a smooth water flow. They also work well with PVC pipe fittings for a secure and leak-free connection in sewer pipe systems.

    Lightweight uPVC drainage pipes are used in various plumbing and drainage systems due to their durability and easy installation. They are commonly used in drainage pipes and fittings, sewerage pipes, underground drainage pipe and more. These pipes are ideal for residential, commercial and industrial projects to ensure smooth water flow and leak-proof connections. They also work well with PVC pipe fittings for efficient sewer pipe systems, which makes them a reliable choice for waste and water drainage applications.

    Lightweight uPVC drainage pipes and fittings are commonly used in homes, buildings and industries for carrying wastewater and rainwater. They are ideal for underground drainage systems, rooftop rainwater collection and sewage disposal. These pipes are also used in agricultural irrigation and road drainage due to their durability and resistance to corrosion. Their lightweight nature makes them easy to transport and install, which reduces labour costs. uPVC drainage and sewer pipes are a popular choice because they are long-lasting, low-maintenance and cost-effective.

    Yes, uPVC drainage pipes are highly resistant to chemical damage. They do not react with acids, alkalis or other common chemicals found in wastewater, which makes them suitable for sewage and industrial drainage systems. Unlike metal pipes, uPVC does not corrode or rust, ensuring a longer lifespan with minimal maintenance. This chemical resistance makes them suitable for various applications, including factories, laboratories and wastewater treatment plants, where exposure to harsh chemicals is common.

    Underground drainage pipes are essential for managing wastewater and rainwater efficiently. They help prevent waterlogging, soil erosion and damage to buildings by directing water away safely. These pipes are commonly used in sewerage pipes and, drainage pipes and fittings, systems to ensure smooth and hygienic water disposal. Made from durable materials like uPVC, they resist corrosion and leakage, which makes them a long-lasting solution. Properly installed underground drainage pipe systems help maintain a clean and safe environment in residential, commercial and industrial areas.

    Yes, underground drainage pipes, especially those made of uPVC and HDPE, are highly resistant to corrosion. Unlike metal pipes, they do not rust or degrade when exposed to moisture, chemicals or soil conditions. This makes them ideal for long-term use in sewage systems, stormwater drainage and industrial waste disposal. Their non-corrosive nature ensures durability, reduces maintenance costs and prevents leaks or blockages, which makes them the best choice for underground drainage pipes and fittings.

    Pipe schedules tell us how thick the pipe walls are. Higher schedule numbers (like Schedule 80) mean thicker walls that can handle more pressure. Schedule 40 pipes have medium thickness and are used for low to moderate-pressure jobs like home plumbing, irrigation and drainage. If you need a pipe for high-pressure systems (like industrial use), Schedule 80 is a better choice. Choosing the right schedule ensures the pipe is strong enough for the job.

    Underground drainage pipes should be cleaned every two years to prevent blockages and ensure smooth water flow. However, in areas with heavy usage, tree roots or frequent debris buildup, more frequent cleaning may be necessary. Regular maintenance of the drainage pipe and fittings, such as flushing with water or using drain cleaners, helps keep the system clear and reduces the risk of costly repairs.

    To prevent blockages of underground drainage pipes and fittings and sewer pipes, install drain guards or grates to stop debris, leaves and dirt from entering the system. Regularly flushing the pipes with water and scheduling professional cleaning every two years can help maintain a smooth flow. Avoid pouring grease, fats or food waste down the drain, as they can harden and cause buildup over time. Lastly, ensuring the drainage and sewerage pipes have the correct slope allows water to flow efficiently, which reduces the risk of clogs.

    What are Foamcore Pipes?

    Foamcore pipes are innovative, multilayer pipes designed for durability and efficiency. They feature outer and inner layers made of conventional PVC, built to withstand heavy loads, while the middle layer consists of foamed PVC, adding rigidity and maintaining the pipe’s shape under pressure. This unique construction enhances strength and makes the pipes significantly lighter than solid wall PVC pipes and fittings. Ideal as underground drainage pipes and sewerage pipes, Foamcore pipes offer a reliable solution for efficient water management.

    Why buy Foamcore Drainage Pipes and Fittings?

    The solid wall PVC pipe on the left shows typical distortion under load, which is expected in such pipes. In contrast, the Foamcore pipe on the right, under the same load, distributes pressure more evenly due to its unique “I-Beam” structure. This ability to absorb load makes Foamcore pipes are the ideal choice for PVC drainage pipes and fittings, where soil pressure can strain pipe surfaces. Unlike solid wall pipes, which may rupture over time due to continuous soil pressure, Foamcore pipes offer greater durability. The foamed PVC layer absorbs stress, ensuring a longer lifespan and reliable performance in drainage and sewer pipe systems.

    Product Standards

    Astral Foamcore pipes are manufactured to meet Indian, European and international standards for structured wall pipes used in drainage pipes and fittings, as well as sewerage pipes. Designed based on stiffness classifications, these globally recognised specifications have been trusted for over 25 years.
