2. Pak Arab CPVC Pipes and Fittings (Chlorinated Polyvinyl Chloride)
Pak Arab holds the distinction of being the pioneer CPVC pipe manufacturer in Pakistan — a licensed producer using CPVC compounds sourced from a leading European manufacturer. CPVC pipes are engineered for applications where standard PVC would fail: specifically, hot water systems, high-pressure lines, and chemically aggressive environments.
Why CPVC Over Standard PVC?
CPVC undergoes additional chlorination, which raises its heat deflection temperature significantly. This means CPVC pipes can safely handle hot water up to 93°C (200°F) — making them the preferred choice for:
- Hot and cold domestic water supply systems
- Solar water heater connections
- Hotel and hospital plumbing
- Industrial chemical processing lines
- High-rise residential buildings where water pressure is elevated
Technical Characteristics:
- Material: Chlorinated Polyvinyl Chloride (CPVC)
- Temperature range: Up to 93°C continuous service
- Pressure rating: Higher than standard PVC at equivalent temperature
- Joining method: CPVC solvent cement (no heat tools required)
- Standards: ASTM D2846, ASTM F441
Available CPVC Fittings: Elbows (90° and 45°), Tees, Reducers, Couplings, End Caps, Unions, Adapters, Ball Valves
3. Pak Arab UPVC Pipes (Unplasticized Polyvinyl Chloride)
UPVC (Unplasticized PVC) pipes are the hardened, rigid variation of PVC pipes with superior dimensional stability and chemical resistance. They are the standard choice for pressure plumbing lines in residential, commercial, and industrial settings.
Key Standards and Schedules:
| Standard | Use Case |
| SCH-40 | Pressure water supply lines |
| SDR-26 | Water drainage |
| SDR-32.5 | Water drainage |
| SDR-41 | Water drainage |
| SDR-64 | Gravity flow lines |
Available Sizes: ½ inch to 6 inches diameter Colors: White, Light Grey
UPVC’s rigidity makes it resistant to deformation under soil loads, traffic surcharges, and hydraulic pressure — a critical attribute for buried pipelines.
4. Pak Arab HDPE Pipes (High-Density Polyethylene)
High-Density Polyethylene (HDPE) represents the next generation of piping for large-scale infrastructure, agricultural, and industrial applications. Unlike rigid PVC, HDPE is semi-flexible, allowing it to absorb ground movement and vibration without cracking — an invaluable property in seismically active or subsidence-prone regions.
Why HDPE is the Infrastructure Standard:
- Exceptional chemical and corrosion resistance
- Long service life exceeding 50 years under standard conditions
- Leak-free heat-fused joints (butt fusion, electrofusion)
- Suitable for both water and gas distribution
- High impact resistance in cold temperatures
Applications in Pakistan:
- Municipal water supply networks
- Irrigation and agricultural water channels
- Industrial effluent and process piping
- Telecom cable ducting
- Mining slurry transfer lines
Pak Arab HDPE pipes are available in a broad range of diameters and pressure ratings (PE 80 and PE 100 grades), with compatible HDPE fittings including saddle clamps, electrofusion couplings, butt-welded reducers, and flanged adapters.
5. Pak Arab PPRC Pipes and Fittings (Polypropylene Random Copolymer)
PPRC (also written as PP-R or PPR) pipes are the modern homebuilder’s first choice for internal hot and cold water plumbing in residential and commercial buildings. Made from Polypropylene Random Copolymer, these pipes combine thermal insulation, corrosion immunity, and a 50+ year service life in a single, lightweight package.
Key Advantages of PPRC:

Frequently Asked Questions (FAQs)
What is the difference between PVC and UPVC pipes from Pak Arab?
PVC (Polyvinyl Chloride) is a broad category of plastic pipes. UPVC (Unplasticized PVC) is a specific formulation that contains no plasticizers, making it harder, more rigid, and more chemically resistant than standard PVC. Pak Arab’s UPVC pipes are recommended for pressure water supply lines (SCH-40) and drainage (SDR series), while their standard PVC pipes are used for general supply, drainage, sewerage, and agricultural applications. Both are produced under the Pak Arab brand by Zaka Sons.
Can Pak Arab CPVC pipes be used for hot water systems?
Yes. Pak Arab CPVC pipes are specifically engineered for hot water applications and can handle continuous service temperatures up to 93°C. They are Pakistan’s first indigenously manufactured CPVC pipes and are joined using CPVC solvent cement — no heat tools required. They are the preferred choice for solar heater connections, hotel and hospital hot water systems, and high-rise buildings.
What sizes are available for Pak Arab PVC and UPVC pipes?
Pak Arab PVC pipes are available in sizes ranging from ½ inch to 8 inches (and up to 24 inches for large-diameter special applications), in standard 6-metre lengths. UPVC pipes are available from ½ inch to 6 inches. HDPE pipes cover a wide range of diameters. PPRC pipes range from 20mm to 110mm. For specific project requirements, contact Arfa Trading for a complete size and availability list.
What are PAKARAB SPIRO pipes, and when should they be used?
SPIRO pipes are Pak Arab’s proprietary spiral-technology PVC pipes, designed for large-diameter gravity drainage and sewerage applications. Their spiral ribbed structure provides exceptional ring stiffness — resisting soil and traffic loads — while remaining significantly lighter than equivalent solid-wall pipes. They are ideal for municipal storm drains, underground sewers, culverts, and industrial drainage. Available in 5-inch and 8-inch widths with a load-bearing capacity of 5,000 kg.
Are Pak Arab pipes certified and safe for potable (drinking) water?
Yes. Pak Arab pipes that are rated for potable water supply — particularly UPVC SCH-40, CPVC, and PPRC pipes — are manufactured using food-grade raw materials and are tested to ensure no leaching of harmful substances into the water supply. They comply with PSQCA standards, which govern pipe safety for drinking water applications in Pakistan.
What is the difference between SDR-26, SDR-41, and SDR-64 in UPVC pipes?
SDR stands for Standard Dimension Ratio — the ratio of the pipe’s outer diameter to its wall thickness. A lower SDR number means thicker walls and higher pressure tolerance. SDR-26 and SDR-32.5 are suited for water drainage systems with moderate pressure. SDR-41 is a standard drainage grade. SDR-64 is designed for gravity flow (low or zero pressure) systems such as storm drains and sewer mains.
How are PPRC pipes joined, and do I need special tools?
Pak Arab PPRC pipes are joined using heat fusion (socket fusion) — a process where a handheld fusion tool heats the pipe end and fitting socket simultaneously, then the two are pressed together to form a seamless, homogeneous joint. This requires a dedicated PPR fusion welding machine (socket or butt fusion tool). The joint becomes stronger than the pipe itself and is completely leak-proof. Unlike PVC, PPRC does not use solvent cement.
How do I identify genuine Pak Arab pipes versus counterfeit products?
Genuine Pak Arab pipes carry:
The PAK ARAB brand name printed or embossed on the pipe body.
Manufacturer details: “Zaka Sons (Pvt.) Ltd., Karachi”.
Pipe class, nominal size, pressure rating, and production batch code.
Color-coded products consistent with product standards (e.g., white for standard PVC, grey for UPVC).
Always purchase from an authorized dealer like Arfa Trading to guarantee product authenticity and warranty coverage.
What is the expected lifespan of Pak Arab plastic pipes?
Under standard service conditions and correct installation, Pak Arab UPVC and PVC pipes have an expected service life of 25–35 years. HDPE pipes are rated for 50+ years. PPRC pipes also offer a service life of 50 years when used within their rated temperature and pressure limits. These lifespans significantly exceed those of galvanized iron (GI) pipes, which are susceptible to corrosion and scaling.
