Astral Poly Technik Ltd is very proud to introduce CHLORINATED POLY VINYL CHLORIDE [CPVC] for the first time into this part of the globe, under license from Lubrizol, [formerly Noveon, USA] under brand name Astral FlowGuard
CPVC. It is also manufacturing Industrial Piping System under brand name Astral Corzan
CPVC. It has a techno commercial joint venture with Specialty Process LLC, USA, the world leaders of manufacturing FlowGuard
CPVC Pipes and Fittings in USA since last 28 Years.
pipes and fittings, manufactured by Astral Poly Technik Ltd, are made from the specialty plastic, chemically known as Temperature Chlorinated Poly Vinyl Chloride [CPVC]
. This CPVC compound shall meet cell class 23447 B as defined by ASTM D1784 and have a design stress of 2000 PSI and a maximum service temperature upto 93°C.
Pipes are produced in copper tube size (CTS) from 15 mm (½”) to 50 mm (2”) with two different standard dimensional ratios - SDR-11 and SDR-13.5. The fittings are produced as per SDR 11. All Astral CPVC SDR 11 and SDR 13.5 pipes are made from identical CPVC compound material having same physical properties. The CPVC fittings are manufactured from compound material which meets all the requirement as per ASTM standard. CPVC pipes of Copper Tube Size (CTS) dimensions can also be applied to CPVC (IPS) dimensions by using IPS x CTS fittings. The CPVC pipes from 15 mm (½”) to 50 mm (2”) are also produced as per IS 15778 standard in both class that is Class 1 (SDR 11) and Class 2 (SDR 13.5).
Apart from having the same physical properties, SDR 11 and SDR 13.5 which are having different wall thickness and therefore, at any given temperature, they have different pressure ratings. For e.g.
|Temperature (°C) |
|Pressure Rating |
| ||(PSI) |
| (Kg/Sq.Cm) |
|SDR 11 ||23 |
|SDR 13.5 ||23 |
Astral also produces FlowGuard pipes in iron pipe size (IPS), available sizes are 65 mm (2½”) to 300 mm (12”) in SCH 40 and SCH 80 which meets the requirements of ASTM F 441. The pressure ratings varies with schedule pipe size and temperature.STANDARDS & SPECIFICATIONS :
