About

Astral DWV


ASTRAL DWV system comprises of uPVC foam core pipes and uPVC click ring type fittings. Both the products are new and unique in nature compared with traditional products available in market.

DWV FOAMCORE PIPES:

DWV Foamcore pipes are basically multilayer pipes having outer and inner layers of conventional PVC and middle layer of foamed PVC. Outer and inner layers are designed to take the load while middle layer of foamed PVC gives rigidity and maintains the shape of the pipe under load. It reduces total weight of pipe and makes it light when compared to solid wall PVC pipes.

STANDARDS:

ASTRAL DWV pipes and fittings are intended for use above and below ground including exposure to direct sunlight and are manufactured as per requirements given in most widely used Europeon & International standards for drainage & sewerage.

COLOUR & MARKING

ASTRAL DWV pipes and fittings are manufactured in dark grey colour in a semi-gloss finish which is opaque and flawless. All DWV pipes and fittings are marked with Batch No. / Lot No. which includes the month / year of manufacture.

APPLICATIONS:

The pipes and fittings are intended for non-pressure drain, waste & vent applications and have been independently accessed and recognised as quality products.

DWV CLICK RING FITTINGS:

Click ring fittings are unique in nature having one rubber ring and one additional ring known as ”Click ring” which is fitted over the specially designed socket geometry of ASTRAL DWV sewer & drain fittings. This ‘Click ring’ ensures the locking of rubber ring within the groove of fittings. The rubber rings are also specially designed having unique geometry and PP cord inside which provides the proper locking to rubber ring and also stiffness against the force of Click ring when fitted over the drain fittings.

FEATURES & BENEFITS:

  • Light weight & strong
  • Reduction in noise level
  • High impact strength
  • High temperature range
  • Leakage elimination
  • High flow rates
  • Longer service life
  • Cost savings

AVAILABLE SIZE:

75 mm, 110 mm, 160 mm with stiffness class SN2, SN4 and SN8

Features and Benefits

DWV PIPES ADVANTAGES

LIGHT WEIGHT & STRONG:

ASTRAL DWV Foamcore pipes are light in weight compared to solid wall pipes and give more strength compared to solid wall pipes due to their unique multilayer construction.

REDUCTION IN NOISE LEVEL :

Due to the middle layer of foamed PVC, ASTRAL DWV Foamcore pipes have very good insulating properties which act to reduce the noise generated by transportation of fluid inside the pipe. This will be very much beneficial in large buildings.

HIGH IMPACT STRENGTH :

Due to the middle layer of foamed PVC, ASTRAL DWV Foamcore pipes can take very high impact compared to solid wall pipes & can reduce the problems of cracking & breaking of pipes while transportation, handling & Installation.

HIGH TEMPERATURE RANGE:

ASTRAL DWV Foamcore pipes can be used for high temperatures compared to solid wall pipes as the foamed layer can withstand high temperatures.

SYSTEM ADVANTAGES HIGH FLOW RATES:

Extremely smooth bores, precision joints and lack of internal projections ensure unrivalled hydraulic capacity over the total life of the system. Flatter gradients can be possible using ASTRAL DWV uPVC drainage systems over conventional systems.

FLAMMABILITY:

UPVC does not support combustion and is inherently difficult to ignite. It also stops burning once the source of heat is removed.

NON CONDUCTIVE:

UPVC is a non-conductor of electricity, and is therefore not subject to galvanic or electrolytic action.

CORROSION RESISTANCE:

The inert nature of uPVC drainage system provides complete corrosion resistance and renders wrapping, coating and lining unnecessary. It also ensures that uPVC drain waste and vent pipes have long operational life compare to conventional asbestos or cast iron systems.

LONGER SERVICE LIFE:

ASTRAL DWV system comprises of Foamcore pipes & click ring type fittings. Both the products are weather resistant, corrosion resistant, and excellent in cushions. effect and ideally suited for sewer & drain applications. These benefits makes ASTRAL "DWV" system most favorable in term of service life.

COST SAVINGS :

ASTRAL DWV piping system can greatly speed up the installation work as they are light in weight, easy to handle and convenient in fixing. The spacing of manholes can be increased due to greatly reduced incidence of blockages and increased flow rates possible with ASTRAL DWV System. reduction in their number makes sound economic sense. All these benefits will lead to very high cost savings when compare to conventional piping system like asbestos or Cast Iron with respect to manpower, material and total time for completion of project work.

UV STABILIZED :

ASTRAL DWV system is UV stabilized which gives protection to the system while being operational in direct sun light.

ENVIRONMENTAL IMPACT :

PVC has a lower feedstock energy especially compared to other polymers and common building materials. It is the least energy intensive of all thermoplastics. In life cycle analyses and independent studies, PVC's environmental impact has been found most favorable, so the more usage of PVC will greatly help to keep our global natural resources intake for longer period of time. It is not polluting air, water or land during manufacturing or service life and can be recycled after prolonged service life.

CHEMICAL RESISTANCE :

The excellent chemical resistance of uPVC pipes to acids, alkalis, oxidising and redcing agents makes it particularly suitable for a wide range of drain applications. uPVC pipes are resistance to all of the chemicals expected to be encountered in drain & waste application.
