Heavy-Duty Carbon Steel Seamless Rolled Rings for Wind Turbine Towers

Carbon Steel Seamless Rolled Rings for Wind Turbine Towers

Iraeta produces carbon steel seamless rolled rings engineered for wind power applications. With dimensions up to 21m outer diameter, 5m height, and 300 tons weight, these rings serve as critical load-bearing connections in wind turbine towers. Our manufacturing integrates material science, forging, heat treatment, and precision machining to deliver high structural strength, fatigue resistance, and corrosion protection for offshore environments.

Key Selling Points

Exceptional Dimensions: Rings up to 21m diameter and 5m height reduce welding and assembly complexity in large towers.
High Strength Carbon Steel: Tailored chemistry and controlled forging ensure yield strength and toughness for 20MW+ turbines.
Fatigue & Corrosion Resistance: Optimized for 24/7 cyclic loads and salt spray exposure in offshore wind farms.
Certified Quality: ISO 9001:2016, PED 2014/68/EU, EN 1090, and ISO 14001 ensure compliance with global standards.

Technical Specifications

Material	Carbon Steel (e.g., S355, S420, custom grades)
Max Outer Diameter	21 m
Max Height	5 m
Max Weight	300 tons
Certifications	ISO 9001, PED, EN1090, ISO 14001, ISO 45001
Applications	Wind turbine tower connections, flange rings

Models and Options

Available as single-piece rolled rings with custom cross-section profiles. Options include pre-machined surfaces, heat treatment (normalizing, quenching & tempering), and ultrasonic testing.

Materials and Structure

Manufactured from carbon steel ingots or continuous cast round billets. The seamless rolling process eliminates weld seams, providing uniform grain flow and enhanced mechanical properties. Typical grades include S355J2, S420N, and proprietary compositions for low-temperature toughness.

Applications

Offshore wind turbine tower flange connections
Transition pieces for monopile foundations
Ring flanges for nacelle components

Customization

Iraeta offers end-to-end customization: material specification, dimensioning, tolerancing, machining, and testing. Contact our engineering team for tailored solutions.

FAQ

What is the lead time for carbon steel wind turbine rings? Lead time depends on size and specification; typically 8-16 weeks after engineering approval. MOQ is 1 unit.
Do you provide material certificates? Yes, we issue EN 10204 3.1 or 3.2 certificates as required.
Can rings be supplied with post-weld heat treatment? We perform heat treatment to meet mechanical properties; specific PWHT can be arranged.
What is the payment term? Standard 30% deposit, 70% before shipment.
How do you ensure quality for offshore applications? We conduct 100% ultrasonic testing, dimensional inspection, and third-party verification.
