Saudi Arabia Oil Tank Project: Precision Rolling with W12NC 4-Roll CNC System
Achieving Zero-Defect Fabrication in Extreme Environments
The Challenge
A leading EPC contractor in Saudi Arabia was struggling with the limitations of traditional 3-roll mechanical machines. For their latest refinery expansion, they needed to roll 30mm thick high-yield carbon steel into 15-meter diameter cylinders.
The primary pain points were:
- Excessive Flat Ends: Previous machines left long unbent edges, requiring costly manual grinding and re-rolling.
- Extreme Climate: Ambient temperatures exceeding 45°C caused standard hydraulic systems to overheat and lose pressure consistency.
- Aggressive Timeline: The project demanded full commissioning and production readiness within 90 days.
The SLM Solution
SLM Forming engineered a customized W12NC 4-roll CNC plate rolling machine specifically for the Middle Eastern industrial environment.
1. Advanced Geometry & Material Strength
We utilized oversized 42CrMo forged rollers with induction hardening to minimize deflection under maximum load, ensuring perfect parallelism during the pre-bending phase.
2. Tropicalized Hydraulic Cooling
To combat the Saudi heat, we integrated a high-capacity industrial air-and-water dual cooling system, maintaining hydraulic oil stability even during 24/7 continuous operation.
3. Smart CNC Spring-back Compensation
The 2026 CNC control system was pre-programmed with adaptive algorithms to calculate material spring-back, allowing for "one-pass" forming with minimal operator intervention.
4. Remote Technical Inspection
Through live high-definition video feeds from our Haian facility, the client’s engineering team performed a virtual pre-shipment inspection, verifying roller hardness and PLC responsiveness in real-time.
The Results
Reduction in Flat Ends
Faster Cycle Times
Roundness Accuracy
"SLM Forming provided more than just a machine; they provided a technical solution to our most difficult fabrication bottleneck. The W12NC system has significantly increased our bidding competitiveness for future oil & gas tenders."
