QFUSION electrofusion fittings are the outcome of over two decades of polymer engineering and field experience at Ghatrān Etesāl. By establishing a full chain—Design → Molding → Quality Control → Packaging—the brand now serves a major share of water, wastewater, irrigation, and gas networks. The fittings are manufactured from self-colored PE100 and carry a unique 90-digit barcode plus laser-etched parameters, enabling full traceability throughout the network’s service life.
Key advantages that set QFUSION apart
- Human-error-free welding – Dual-pin connection to the machine and automatic barcode reading make the process fully automated.
- Mechanical safety – A wide fusion area, PE-coated heating element, and a removable pipe stop in couplers prevent buckling or unwanted pipe movement.
- Chemical and seismic durability – PE100 resists most acids and bases and remains stable during >7-magnitude earthquakes.
- Three-stage quality control – A partner laboratory equipped with IPT (Germany) tests raw materials, in-process parts, and finished products to ISO 4427-3 and EN 1555-3.
- UV-Shield packaging – Multi-layer cartons and antioxidant liners preserve weld quality up to installation.
Components of each fitting
- Connection pins to deliver current to the element
- Visual indicator confirming a complete fusion
- Standard barcode with size, SDR, pressure class, and welding parameters
- PE-coated heating element to prevent wire oxidation
- Removable pipe stopper for maintenance and repairs
Standard installation steps (execution checklist)
- Square-cut and clean pipe ends
- Mark insertion depth
- Scrape the outer pipe surface
- Degrease with approved cleaner
- Insert the pipe to the stopper
- Fix with alignment clamps
- Connect cables and scan the barcode
- Perform fusion and allow undisturbed cooling
Table 1 – Size range and common QFUSION fittings
| Fitting type | Common sizes (mm) | Primary use | Short technical note |
|---|---|---|---|
| Coupler | 20–400 | Branching & repair | With removable stopper |
| Equal tee | 32–315 | Network direction change | 90° branch with uniform fusion |
| 90° elbow | 20–315 | Angle change | Uniform element in both legs |
| Reducer | 25–400 | Diameter transition | Concentric design for minimal loss |
| TF brass-thread adaptor | 20–110 | Metal connection | Water & gas versions |
Standards, SDR, and operating pressure
QFUSION electrofusion fittings are offered in multiple SDRs to cover different pressure classes. Understanding the diameter ↔ wall-thickness relation helps select correctly.
| SDR | Max water pressure (bar) | Max gas pressure (bar) | Example applications |
|---|---|---|---|
| 11 | 16 | 10 | Municipal water mains, city gas |
| 17 | 10 | 6 | Pressurized irrigation |
| 21 | 6 | 4 | Vacuum sewage networks |
Values derived from EN 12201 and EN 1555 for PE100.
Compliance with national & international standards
- Water supply: INSO 14427-3, ISO 4427-3, EN 12201-3

Technical support & after-sales
For each project, QFUSION provides a CSV of welding parameters and a dedicated lab certificate. The technical team can analyze barcode-logged data to monitor the quality of every joint during periodic inspections.
Range of machines & accessories
Beyond fittings, the brand offers electrofusion machines, scrapers, pipeline clamps, and moisture-resistant barcode readers—all with predefined welding profiles for QFUSION codes to minimize on-site commissioning time.
Tamam Baha, as one of QFUSION’s suppliers, provides full product coverage plus pre-purchase consulting, shop-drawing approval, and hands-on welding training at the project site. The company is not the exclusive agent; customers may procure through other authorized channels as well.
