Astral Underground Drainage products are manufactured using state-of-the-art production technology which provides comprehensive range of robust, lightweight and extremely durable drainage products with unparalleled long term performance.
Adjustable Bends are specially designed by Astral to suit with installation of inspection chambers. As the chamber inlet and outlets have fixed angle & position, adjustable bends can be changed depending on the requirement of the size. These bends are available in two different patterns one with 02 pcs (suitable for 5° to 37.5° movement) & 03 pcs (suitable for 0° to 87.5° movement). These bends eliminate use of extra fittings and pipes to get the angle with pipeline and hence very cost effective.
Access is very important on all installations for testing, inspection, and removal of any blockage or debris. Rodding in both directions can be achieved by using a 315 mm or 450 mm Large Inspection Chamber in conjunction with access fittings. Rodding points are normally used in storm water drainage systems where the rodding point is located at the head of the drain run connection to a chamber, and being no further than 22 meters away from the chamber. The rodding point should be enclosed in a concrete surround to provide support and to ensure that it does not become mislaid at ground level.
Astral’s innovative design for 315mm, 355mm & 450mm bring unmatched flexibility to the underground drainage. The joints & seals are designed in such a way that they can accommodate the movement of connecting piece up to 3° in any direction. Astral also introduces the Drain Hulk with 500 mm, 600 mm Inspection chambers & 800 mm, 1000 mm manhole for public sewer lines.
