An Eastern European country's water authority embarked on a major flood control infrastructure modernization following severe flooding events. The project required producing ultra-large-diameter corrugated HDPE pipe (1200–1600mm) for major drainage culverts and river protection systems.
A regional engineering contractor secured a 10-year supply contract to furnish all corrugated pipe for the national flood control program, estimated at 200,000+ linear meters.
The SL1600 is one of Suba's largest standard configurations. The contractor selected it because:
Contract finalized in Q4 2023. Total investment: €420,000 including machine, installation, training, and 24 months of technical support. Delivery target: Q2 2024.
Suba manufactured the SL1600 with additional structural reinforcement for the large-diameter application. Shipment via specialized heavy-goods transport in three containers arrived in Q2 2024. On-site assembly took 8 weeks, with continuous Suba supervision.
The contractor's team completed a 4-week technical program covering setup, troubleshooting, and maintenance protocols.
The SL1600 entered production in Q3 2024 and completed initial testing by Q4. Performance metrics:
| Specification | Target | Actual |
|---|---|---|
| Outer Diameter Range | 1200–1600mm | 1200–1600mm ±3mm |
| Wall Thickness | 5–7mm | 6.2mm ±0.15mm |
| Monthly Output | 2,500 m | 2,680 m |
| Corrugation Consistency | ±5% | ±1.8% |
| Defect Rate | <1% | 0.3% |
Preliminary feedback indicates that the flood control structures built with this pipe will provide 50+ years of service life, significantly reducing long-term infrastructure costs.
"The SL1600 is a game-changer for large-scale infrastructure. We're now supplying pipe for some of the most critical flood protection systems in the region. The precision and consistency of the Suba machine is unmatched." — Project Lead, Eastern European Engineering Authority
