ASTRAL CHEM PRO is proven CPVC piping system meeting all challenging application requirement of industrial piping system. It gives trouble free service to the industry for years together.


ASTRAL CHEM PRO industrial piping system can be used up to 93°C temperature & intermittent up to 110°C & pressure based on the pipe sizes. ASTRAL CHEM PRO CPVC industrial piping system is suitable for many industrial requirements like Metal Treating Pump & Raiser, Food & beverages, Industrial waste water, Chemical processing etc. ASTRAL POLY TECHNIK LIMITED is the only Indian company manufacturing industrial grade Chlorinated Polyvinyl Chloride (CPVC) Pipes of schedule 40 & 80 and fittings of schedule 80 confirming to ASTM Standards ranging from ½”(15mm) to 12” (300mm). All ASTRAL CHEM PRO CPVC industrial pipes are produced from compound confirming to ASTM D1784.


 Many chemicals encountered in the process industry aggressively corrode most metal equipment resulting in process leaks, flow restrictions and ultimately premature failure. In addition to metals there are other thermoplastics used in industry which get affected by these aggressive chemicals at elevated temperatures and pressures and lead to premature failure. Long Service life, minimum downtime and environmental compliance are critical to the success and growth of firms in the process industry. A challenging effort is required for the industry to achieve the successes where corrosion can decrease piping life, interrupt production and create potential environmental hazards. As a result, these industries often require process-piping systems those are made of materials that can withstand tough industrial environments. Ideally, this means a cost effective material that will resist corrosion and eventually providing mechanical strength, safety and long lasting performance.

GENERAL SPECIFICATIONS: ASTRAL CHEM PRO CPVC Industrial Systems are produced from specialty plastic compounds known as post-chlorinated polyvinyl chloride (CPVC). The compounds meet cell class 24448 as defined by ASTM D1784 and have a design stress of 2000 psi and a maximum service temperature of 93ºC. The compound is listed by the National Sanitation Foundation for use with portable water in accordance with NSF Standard 14. The colour is light grey.

Pipe: Pipe meets or exceeds the requirements of ASTM F441 in Schedule 40 and 80 dimensions. Available in size range 15mm (½”) to 300 mm (12”).

 Fittings: Fittings meet or exceed the requirements of ASTM F437 (Schedule 80 threaded) or ASTM F439 (Schedule 80 socket). Available in size range ½” to 12”. 

Primer/Solvent Cement: All socket type joints are made up employing primer and solvent cements that meet or exceed the requirements of ASTM F656 and ASTM F493. Both primer and solvent cement confirm with the requirements of NSF Standard 14. Only CPVC solvent cement and primer are to be used when making CPVC solvent cement joints.  Marking and Uniformity: Pipe and fittings made from ASTRAL CHEM PRO CPVC compounds are clearly marked with the manufacturer’s name or trademark, material designation and applicable ASTM Standard.


Applicable Standards: 

ASTM D1784: Standard Specification for Rigid Polyvinyl Chloride (PVC) and Chlorinated Polyvinyl Chloride (CPVC) Compounds.

ASTM F441: Standard Specification for Chlorinated Polyvinyl Chloride (CPVC) Plastic Pipe, Schedules 40 and 80.

ASTM F437: Standard Specification for Threaded Chlorinated Polyvinyl Chloride (CPVC) Plastic Pipe Fittings, Schedule 80.

ASTM F439: Standard Specification for Stocket-Type Chlorinated Polyvinyl Chloride Plastic Pipe Fittings, Schedule 80.

ASTM F402: Standard Practice for Safe Handing of Solvent Cement and Primer Used for Joining Thermoplastic Pipe and Fittings.

ASTM F656: Standard Specification for Primers Used in Solvent Cement Joints of Polyvinyl Chloride (PVC) Plastic Pipe and Fittings.


BASIC USE: ASTRAL CHEM PRO CPVC pipes and fittings are intended for use in both pressure and drain applications in general chemical manufacturing plants, pulp and paper plants, waste water treatment plants, metal treating/electroplating plants, water purification plants, and food processing plants where excellent resistance to corrosion from a wide range of chemicals, acids, and bases at temperatures up to 93°C is required.


 SYSTEM DESIGN: The system is designed in accordance with standard industry practice for thermoplastic industrial piping systems and takes into consideration such factors as pressure and flow requirements, friction loss, operating temperatures, support spacing, anchoring, bracing and thrust blocking, temperature correction factors, joining methods, chemical environment, collapse and loading, and thermal expansion and contraction.


 CAUTIONS/LIMITATIONS: Air or compressed gas should never be used for pressure testing rigid thermoplastic piping systems. Temperature correction factors to be applied when operating temperatures exceed 23° C. Only Schedule 80 pipe may be threaded up to and including 4” size, and threads to be in accordance with ANSI B1.20.1 Taper pipe Thread. Only water soluble oil or water to be used when threading Chem Pro pipe. Digressing type solvents should never be used to clean threads. Only Teflon tape should be used when making plastic connections. Flanged systems should not exceed 150 psi working pressure. Threaded joints should have 50% of the pressure rating of Schedule 80 pipe.


 ASTRAL CHEM PRO CPVC is not recommended for use with most polar organic solvents such as chlorinated or aromatic hydrocarbons, esters, or ketones. Prior testing is recommended when required service includes surfactant, oil, or grease. Consult ASTRAL for specific chemical resistance information.
