Our Heavy-Section Rolled Rings are engineered for high-performance applications in heavy machinery, energy equipment, offshore systems, and complex custom-engineered assemblies. Unlike standard lightweight rings, these components are specifically designed to maintain absolute structural soundness across larger wall sections and heavier cross-sections, ensuring unmatched durability in the most demanding industrial environments.
Primarily supplied as high-quality starting materials, these rings are optimized for further machining into functional supports, critical flanges, or large-scale circular components. By focusing on precise forging reduction, rigorous temperature control, and expansion stability, we deliver forged blocks that provide superior dimensional stability and high strength-to-weight ratios for mission-critical infrastructure.

Frequently Asked Questions
Q: What is the primary difference between heavy-section rolled rings and ordinary rolled rings?
The primary difference lies in the wall thickness and structural requirements. Heavy-section rings require much stricter forging reduction and temperature control to ensure the center of the thick wall is as sound as the surface.
Q: Which materials are most commonly used for these heavy forgings?
Depending on the application, we typically use high-strength alloys such as 42CrMo4, 34CrNiMo6, and A105, though we can produce rings according to any customer-provided material drawing.
Q: How do you ensure there are no internal defects in rings up to 600mm thick?
We employ full-volume ultrasonic testing (UT) with high sensitivity settings to detect any internal voids, inclusions, or cracks, ensuring 100% structural soundness.
Q: Can these rings be supplied pre-machined?
Yes, we offer three supply conditions: as-forged, quenched and tempered, or rough-machined with a specific stock allowance defined by the customer for final machining.
Q: What is the maximum weight capacity for a single rolled ring?
Our current production capacity allows for heavy-section rolled rings with a unit weight of up to 30 tons and an outer diameter of up to 8000mm.
Q: What documentation is provided with each shipment?
Each order is accompanied by a comprehensive documentation package, including mechanical property reports, dimensional reports, and an EN 10204 3.1 certification.
