Poly Gharb is a recognized manufacturer of polyethylene (PE) pipes and fittings for water transmission, pressurized irrigation, industrial low-pressure gases, sewer rising mains, cable ducting, and drainage. With first-grade raw materials and process-based quality control, the brand aims to ensure durability, safety, and stable hydraulics across networks.
Brand snapshot & market position
Leveraging thermal fusion technologies and tight dimensional control, Poly Gharb offers a wide range of PE pipes and fittings for municipal, industrial, and agricultural projects. The brand is built on three pillars: consistent quality, scalability from small jobs to major infrastructure, and a complete fittings portfolio for fast, leak-free installation.
Advantages of Poly Gharb PE products
- High abrasion and chemical resistance against aggressive waters and effluents
- Lightweight and faster installation compared with metal or concrete pipes
- Flexibility for uneven terrain; reduced failure risk during seismic events
- Low hydraulic roughness (lower head loss and more efficient pumping)
- Long service life under standard operation; UV-stabilized via coating/additives
Product range & typical spans
Sizes and pressure classes below are industry-typical and can be manufactured to project specifications. When specifying, confirm the exact size/class mix for your project.

SDR–PN mapping for PE100 (rule-of-thumb)
The following values are commonly used for design at 20 °C. Final selection must follow project standards, operating temperature, and safety factors.
Table 2 — SDR ↔︎ PN (typical design guide)
| Material | SDR | Approx. PN (bar) | Technical note |
|---|---|---|---|
| PE100 | 11 | 16 | Suitable for primary municipal/industrial mains |
| PE100 | 13.6 | 12.5 | Balanced strength and efficiency |
| PE100 | 17 | 10 | Widely used in irrigation & mid-line transfer |
| PE100 | 21 | 8 | Long runs with lower head loss |
| PE100 | 26 | 6.3 | Low-pressure or duct applications |
Applications
- Urban & rural water: Hygienic distribution and trunk lines with minimal leakage.
- Agriculture: Sprinkler/drip, risers, and inter-farm lines; excellent resistance to fertilizers and salts.
- Industry: Neutral or mildly corrosive fluids, effluents, and low-pressure process lines.
- Power & telecom: Ducting for mechanical and moisture protection.
- Drainage & stormwater: Collection and conveyance with minimal sedimentation.
Materials & classes
Common grades are PE80 and PE100; for higher pressure at reduced wall thickness, PE100 is preferred. Always track material traceability (batch certificates) and exact resin grade for project QA/QC.
Reference standards & quality control
Request certificates of conformity to standards such as ISO 4427, EN 12201, and the relevant national standard. Key controls include hydrostatic testing, dimensional checks (OD/wall), ovality, and pipe marking. Electrofusion fittings should include barcodes or weld parameters.
Jointing methods & installation notes
- Butt fusion: For medium to large diameters; requires facing, precise alignment, and controlled heater temperature.
- Electrofusion: Ideal for repairs and critical joints; fast installation and high traceability.
- Flanged: Interface to valves/equipment; allows disassembly and periodic service.
- Compression/threaded: For small diameters and low-pressure branches.
Execution tips: Clean/dry pipe ends; control ambient temperature and wind; use restraint rings at direction changes and thrust points; provide sand bedding and proper compaction to avoid point loads.
Technical selection & lifecycle guidance
- Flow & head loss: Size diameter by design flow and allowable velocity (typically 0.6–1.5 m/s for water). Rule of thumb:
Q = (π D² / 4) × V. - Working pressure & temperature: Allow for pressure derating at elevated temperatures.
- Routing: Respect minimum bend radius (function of SDR and diameter).
- Lifecycle efficiency: Consider pipe/fittings, installation, and pumping energy over the service life.
Handling, storage & care
Store coils/reels on flat, smooth surfaces away from sharp edges; avoid contact with raw metal edges. Outdoors, use covers to protect from intense sunlight and mechanical damage. Do not throw or drag assembled components.
Common issues & remedies
- Fusion-joint leakage: Often due to contamination or uneven pressure—repeat fusion with proper preparation.
- Ovality from storage: Caused by poor stacking—use pallets and proper restraint.
- Unexpected head loss: Undersized diameter or fouling—recheck hydraulics and clean.
- Failure at bends: Missing restraints or short anchor lengths—install thrust blocks or restrained joints.
