Astral Poly Technik Limited is the first licensee of Lubrizol of USA(formerly known as BF Goodrich a fortune 500 company) and have equity joint venture with Specialty Process LLC of USA (manufacturing CPVC plumbing system since 30 years) to manufacture and market the most advanced CPVC plumbing system for the first time in India.

Astral Corzan HP

Industries often require process-piping systems which are made of materials that can withstand tough industrial environments. Ideally, this means a cost effective material that will resist corrosion while also providing mechanical strength, safety and long lasting performance.


•   MECHANICAL STRENGTH : When non-metals replace metal in process applications for corrosion reasons, the mechanical strength of the system becomes a key design consideration. In order to ensure a safe and reliable operation, non-metals must provide sufficient mechanical strength to meet design criteria such as maximum operating pressure, strength at elevated temperature, equipment service life and structural integrity.

•   MINIMIZING PROCESS LIFE CYCLE COSTS : The Astral CORZAN HP Industrial System provides adequate tensile strength for operations up to 93°C (200°F). In addition, the Astral CORZAN HP System can be expected to maintain its pressure-bearing capabilities for 50 years and beyond.

The Astral CORZAN HP Industrial Piping System inherently has both the corrosion resistance and mechanical strength required for many process applications at a total installed cost lower than those of carbon steel.

•   CHEMICAL RESISTANCE : ASTRAL Astral CORZAN HP CPVC industrial pipes and fittings are inert to most mineral acids, bases, salts and aliphatic hydro carbons, and compares favorably to other non-metals in these chemical environments.
