Features & Benefits

High Performance Properties

Resistance To Hot Water

Astral DrainPro piping system can withstand extreme temperature conditions. Astral DrainPro piping system can work flawlessly up to 95°C for short term exposure and up to 90°C for long term exposure, making the system ideal for the commercial kitchens & trade waste applications.

Improved Acoustic Performance

Mineral filled Polypropylene material keeps system shock and vibration proof. This special characteristic helps to reduce noise during waste discharge. 3 layer pipe construction and PP mineral filled material of Drainpro provides good sound insulating properties.

Excellent Chemical Resistance

Drainage and Sewerage piping system often encounter extreme conditions due to presence of various chemicals in waste water. Astral DrainPro piping system has excellent resistance to such chemicals that keep the system away from corrosion, rusting and pitting. Due to Polypropylene material it can withstand wide range of chemicals ranging from pH 2 to pH 12. This makes the DrainPro piping system ideal choice for laboratory discharge.

High Impact Strength And Fatigue Resistance

Semi-crystalline nature of PP imparts high impact and fatigue resistance that helps Astral Drainpro to overcome many challenges of traditional system like breakages and damages due to transportation, handling and storage of pipes on site.

Smooth And Abrasion Resistance Inner Surface

The smooth and abrasion-resistant inner surface enable obstacle-free flow by keeping inner surface free from deposits and scaling.


The manufacturing and installation processes of Astral DrainPro piping system utilise very less energy and 100% recyclable material makes the system Eco-friendly solution.

Other Features & Benefits

Lower Thermal Expansion

Special mineral filled PP 3-layer construction in Astral DrainPro piping system reduces the thermal expansion making the system highly recommended when external and internal temperature fluctuation are more. The thermal expansion of DrainPro is almost half of the HDPE material. Also, the push-fit connection system makes it a more versatile and stable system during such changes in length due to expansion and contraction.

UV Stability And Long Life

Draipro piping is manufactured using UV Stabilized material which protects the pipes and fittings from the degradative attack of UV improving the lifespan of the product

Simple And Quick Joining

The unique joining of pipe and fittings with the push-fit rubber ring provides the leak-proof solution for waste-water discharge. Even replacement and transfer of piping are very easy without cutting pipe.

Lower Cost

Push-fit rubber joining provides easy installation which saves time & human effort. Its light weight makes installation, handling and transportation easier and also cost-effective in comparison to heavy metallic piping systems.

Shock And Vibration Proof

Rigid structures are prone to breakage due to vibrations. Additional flexibility is given to the drainage piping system by not glueing or welding the joints. The characteristic feature of the push fit system of DrainPro provides not only air-tight and leak-proof connection but also a shock and vibration resistant joint. This helps to maintain pipe integrity in the event of an earthquake
