The Bwer Advantage for Three-layer Polyethylene Pipe
Discover why Bwer Pipes is recognized as the leading and most trusted manufacturer in Iraq.
Triple-Layer Co-Extrusion
Produced in a single manufacturing pass. The three layers are molecularly fused, combining an ultra-tough outer skin, a structural core, and a low-friction inner flow layer.
Integrated Scratch Protection
The outer layer is colored differently (typically blue or red) to serve as a scratch wear indicator during trenchless horizontal drilling.
100% Resistant to Chemical Permeation
Ideal for laying pipes in industrial refinery sites or contaminated ground where hydrocarbon permeation risks are high.
Saves Excavation Bedding Costs
Requires no sand bed. The tough outer protection shield allows the use of coarse backfill aggregates directly, reducing civil costs.
Technical Specifications
Step-by-Step Field Guidelines
1. Alignment and Setup
Arrange pipe runs. Inspect the outer colored skin for any deep shipping scratches.
2. Butt Fusion Welding
Weld pipes using CNC-controlled butt-fusion welding machines to ensure uniform weld bead structure.
3. Trench Placement
Lower pipe directly into the raw dirt trench. No sand bedding is required.
4. Deflection Inspection
Conduct ultrasonic thickness scanning or internal pigging to ensure zero cross-section deflection.
Quality Control & Lab Testing
Manufactured in our state-of-the-art facility in Kalar, Garmian. Tested on every single batch.
Co-Extrusion Adhesion Test
Verifies that the three layers cannot be mechanically peeled or separated.
Slow Crack Growth Resistance
Validates pas 1075 compliance (SCG resistance > 8760 hours).
Melt Flow Rate (MFR) Test
Confirms polymer stability across all three layers.
Hydrostatic Pressure Test
100-hour and 1000-hour pressure tests at 80°C to verify service lifetime.
Frequently Asked Questions
Common questions regarding implementation in Iraqi governorates.
Q: What do the color layers indicate?
A: The outer colored skin indicates pressure rating or service type (e.g. blue for drinking water) and serves as a depth-gauge for scratch inspection.
Q: Can it be electrofused?
A: Yes, but the outer protective skin must be scraped off at the joint site before electrofusion to expose the clean PE100 core.
Q: Does it cost more than single layer pipe?
A: While the material cost is slightly higher, the removal of sand bed transport costs makes it cheaper on site.
