In the #Pakistani #market, **4B** is a recognized #local #brand offering a comprehensive range of PPRC (Polypropylene Random Copolymer) pipes and fittings. These are widely used for #residential and #industrial #hot and #cold #water #systems due to their durability and #high #pressure #resistance.

Below is the technical breakdown for **#4B #PPRC PN 20** and **PN 25** specifications and how they compare to other local standards.

### Technical Specifications

| Feature | PN 20 (S 2.5) | PN 25 (S 2.0) |

|---|---|---|

| **Pressure Rating** | 20 Bar (290 psi) | 25 Bar (362 psi) |

| **Wall Thickness** | Thicker (e.g., 3.4mm for 20mm pipe) | Heaviest/Thickest (e.g., 4.2mm for 20mm pipe) |

| **Primary Use** | #unplasticized #High-#pressure hot & cold water | Heavy industrial & high-rise plumbing |

| **#Max #Temperature** | Up to 70°C – 80°C | Up to 95°C (Short peaks) |

| **Standard Length** | 4 Meters (Standard) | 4 Meters (Standard) |

### Key Features of Local Brands (4B, Popular, IIL)

* **Material Quality:** Most reputable local brands like 4B use food-grade #PPRC #Type 3 material, which ensures the water remains odorless and #non-#toxic.

* **#Heat #Resistance:** Designed to withstand the high temperatures required for geyser connections and solar water heating systems common in Pakistan.

* **Fusion Welding:** Fittings are designed for thermal socket fusion, creating a leak-proof monolithic joint that is often stronger than the pipe itself.

* **Availability:** PN 20 is the standard "heavy-duty" choice for most high-end residential projects, while PN 25 is typically reserved for specialized boiler lines or extreme pressure requirements.

### Comparison with Other Local Brands

While 4B is a solid local choice, you may also encounter these top-tier Pakistani manufacturers in the same category:

1. **IIL (International Industries Limited):** Known for being PSQCA certified and widely used in large-scale infrastructure.

2. **Popular Pipes:** Very common in the retail market with a massive range of fittings (Elbows, Tees, Unions, and Metal-insert Spindles).

3. **Dadex (Polydex):** One of the oldest names in the industry, often cited for high material۔

#RAKtherm #PPRC #Stabi pipes with #aluminum #foil are #high-#performance composite pipes specifically engineered to address the thermal expansion issues typically found in standard plastic piping. Manufactured in the #UAE by Gulf Plastic and Converting Industries (Tahweel), they are a staple in high-end plumbing and #HVAC projects.

🛠 Description & Construction

The Stabi pipe is a multi-layer composite system designed for "stability." Its unique structure includes:

* Inner Layer: High-quality PP-R (Polypropylene Random Copolymer) 80, which is hygienic and smooth.

* Adhesive #Layer: A specialized hot-melt glue that bonds the plastic to the metal.

* Aluminum Layer: A 0.2 mm thick aluminum foil that provides a mechanical oxygen barrier and structural rigidity.

* Outer Layer: A protective PP-R coating. Some versions (Stabi UV) include a black layer for outdoor protection against sunlight.

📋 Key Specifications

| Feature | Details |

|---|---|

| Origin | Ras Al Khaimah (RAK), UAE |

| Pressure Ratings | Typically available in PN 20 and #PN25 |

| #Temperature #Range | Continuous up to 70°C, short-term peaks up to 100°C |

| Service Life | 50+ years under standard operating conditions |

| Standards | Complies with DIN 8077/78 and EN ISO 15874 |

| Sizes (OD) | Commonly ranges from 20mm to 110mm |

| Expansion Coeff. | ~0.03 mm/mK (75% less expansion than standard PPR) |

✨ Benefits & Features

* Reduced Thermal Expansion: The aluminum layer makes the pipe behave more like a metal pipe, preventing the "snaking" or sagging that happens when hot water flows through regular PPR.

* Oxygen Barrier: The foil prevents oxygen from permeating the pipe wall, which is critical in closed-loop heating systems to prevent the corrosion of metal radiators and boilers.

* High Pressure/Heat Resistance: Ideal for high-rise buildings and industrial applications where hot-melt stability is mandatory.

* Hygienic: Non-toxic and resistant to bacterial growth, making it safe for potable (drinking) water.

🏗 Usage & Applications

* Hot & Cold Water Systems: The primary choice for pressurized water delivery in residential and commercial buildings.

* Central Heating: Used for radiator connections and underfloor heating due to its oxygen-barrier properties.

* HVAC Systems: Excellent for chilled water lines in air conditioning systems.

* Industrial Piping: Suitable for transporting various chemicals and fluids due to its high chemical resistance.

* Outdoor Installations: The Stabi UV version (with the black outer layer) is specifically designed for external use under direct sunlight.

> Installation Note: Unlike standard PPR, Stabi pipes require a peeling tool to remove the outer PP-R and aluminum layers before heat fusion welding to ensure a secure, leak-proof bond between the fitting and the inner pipe layer.
