Our CPVC Hot Water & Industrial Piping are manufactured using 100% virgin lead-free resin under strict ISO 9001 and Saudi Aramco Vendor #10116102 quality standards, delivering superior burst strength, thermal stability, and corrosion immunity.
Depending on the exact specification, systems comply with ASTM F441, ASTM F439, ASTM D2846, Saudi Aramco 9COM.
Available in sizes from 1/2" to 8" IPS, supporting Schedule 40 & Schedule 80 (Up to 450 PSI at 23°C).
Thermoplastic piping provides 100% galvanic corrosion immunity, making it impervious to high sulfate and chloride sabkha soils found in coastal Saudi regions.
Every order is accompanied by factory mill test certificates (MTC), dimensional compliance sheets, and third-party laboratory burst test reports.
Yes, our Jeddah fabrication plant manufactures matching sweep bends, tees, and flange adaptors fully rated for system working pressures.
Western Province: 24h; Central/Riyadh: 24-48h; Eastern/Northern/Southern: 48-72h.

CPVC prevents biofilm formation and bacterial colonisation (such as Legionella pneumophila), withstands aggressive chlorine hyperchlorination treatments, and never experiences pitting corrosion common in copper pipes.
Installers must use specialized heavy-bodied CPVC solvent cement complying with ASTM F493 (such as Corzan or Weld-On 714/724) preceded by an aggressive purple primer conforming to ASTM F656.
With 67% chlorine saturation, CPVC possesses outstanding chemical inertness against concentrated sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide (caustic soda), and brine across industrial plants.
Due to reduced flexural modulus at elevated temperatures, horizontal support hangers must be spaced closer (typically every 1.0m to 1.5m for 2" pipe at 80°C) with continuous support trays recommended for 90°C service.
CPVC has a Limiting Oxygen Index (LOI) of 60% (ambient air is 21% O2), meaning it cannot sustain combustion in air. It produces minimal smoke and satisfies UL 94 V-0 and NFPA 255 fire safety ratings.
Piping must cure fully (minimum 24–48 hours depending on temperature and diameter) before being hydrostatically tested at 1.5 times working pressure using clean water. Pneumatic (air) testing is strictly prohibited.
