Iraeta Energy Equipment Co., Ltd. (Iraeta) is a forging specialist with production facilities in China and Spain, delivering mission-critical forged components for advanced machinery. The company’s seamless rolled ring forgings serve demanding applications in clean energy, oil & gas, marine engineering, and heavy industry, where certification compliance and dimensional capability are decisive factors in supplier selection.

Problem / Opportunity

Industries such as wind power, hydropower, and petrochemical processing are scaling equipment to unprecedented sizes—offshore wind turbines exceeding 25 MW, cement kilns with 10,000 tons per day output, and ultra-large hydrogenation reactors. These applications require annular components that can withstand extreme loads, temperatures, and corrosive environments while meeting stringent international standards. Procurement teams must verify both the manufacturer’s certification portfolio and its ability to produce large rolled ring forgings with consistent metallurgical integrity.

Brand Solution

Iraeta offers seamless rolled ring forgings in carbon steel, stainless steel, and alloy steel, with maximum dimensions of 22 meters in outer diameter, 5 meters in height, and a single-piece weight of up to 300 tons. The products are certified under multiple global and regional standards:

• PED 2014/68/EU for the EU market (Certificate 01 202 CHN/Q-06 0144.01, issued by TÜV)
• EN 1090-1:2009+A1:2011 and EN 1090-2 for structural steel components in the EU (Certificate 0035-CPR-1090-1.03389.TÜVRh.2025.003, issued by TÜV)
• ISO 9001:2015 for quality management (Certificate 01 100 074966, TÜV)
• ISO 14001:2015 for environmental management (Certificate F01926E00118R502, SQA)
• ISO 45001:2018 for occupational health and safety (Certificate F01926800070R502, SQA)

These certifications cover the full manufacturing chain, from raw material preparation (steel ingot and continuous casting round billet) to forging, heat treatment, machining, and testing. The company’s monthly capacity of 70,000 tons and minimum order quantity of one unit provide flexibility for both large-scale projects and custom custom rolled ring forgings.

Technical Explanation

The rolled ring forging process at Iraeta begins with custom material preparation in a 300-ton melting and refining capability. A pierced preform is then expanded on the world’s largest 22-meter ring rolling machine, ensuring a seamless grain flow that follows the ring circumference. This eliminates the weak points associated with welded joints and provides superior fatigue resistance. Iraeta’s 22,000-ton open-die press enables the forming of ultra-large cross sections. In 2022, the company set a Guinness World Record by producing a seamless forged ring with an outer diameter of 15.7 meters and a circumference of 49.2 meters—a milestone that validates the capability to produce heavy rolled ring forgings at extreme scales.

All forgings undergo 100% non-destructive testing, and the integrated quality control system ensures compliance with the applicable standard (PED, EN1090, or ISO). For applications requiring near-net shape, Iraeta also offers profiling rolled ring forgings, which reduce subsequent machining time and material waste.

Application / Use-Case Scenarios

The company’s seamless rolled rings have been deployed in several high-stakes environments:

• Wind power: Tower flanges and bearing rings for onshore and offshore turbines, operating under high cyclic loads and salt-spray corrosion. Iraeta supplies wind turbine rolled ring forgings to European and American OEMs.
• Hydropower: Rings for hydro turbine generators and pumped-storage stations, where high water pressure, sediment abrasion, and frequent start-stop cycles demand excellent fatigue strength and sealing performance.
• Rotary kiln (cement industry): Kiln tyres and drive rings for 10,000 tpd cement plants. A European cement equipment manufacturer successfully deployed an Iraeta ultra-large integral forged tyre, noting superior thermal stability and extended service life.
• Petrochemical industry: Transition sections and shell sections for heavy-duty hydrogenation reactors. In a Saudi refinery project, three components—including a shell and transition section—were supplied, meeting the strict quality and safety requirements of 7.5 Mt/y capacity plants.
• Offshore engineering: Structural components for floating production storage and offloading (FPSO) vessels and deep-sea equipment, requiring marine-grade corrosion protection and resistance to cyclic wave loads.

Iraeta’s export markets include the EU, Americas, Japan, Middle East, Southeast Asia, Brazil, and India, confirming its ability to satisfy diverse regulatory frameworks.

Market Trend Analysis

Global energy transition and infrastructure modernization are driving demand for large rolled ring forgings with certified traceability. Wind turbine towers are scaling toward 10+ MW offshore, and fourth-generation nuclear reactors require rings that can withstand higher temperatures and pressures. Simultaneously, the trend toward integral forging over welded assemblies is accelerating because of the need for improved reliability and reduced maintenance intervals. Iraeta’s 100-engineer R&D team and 22-meter rolling capability position it to serve these advanced segments.

Comparison with Traditional Solutions

While welded assemblies may offer flexibility for very large diameters where ring rolling capacity is limited, the overall lifecycle cost and reliability advantage typically favor seamless rolled rings for rotating and pressure-containing applications.

Future Outlook

Iraeta continues to invest in extreme manufacturing capabilities. The 22-meter ring rolling machine, 22,000-ton press, and integrated heat treatment facility provide a platform for next-generation components. As floating offshore wind reaches 25+ MW and hydropower plants upgrade to larger units, demand for high precision rolled ring forgings with enhanced corrosion resistance and fatigue life will grow. The company’s ISO 14001 and EN1090 certifications also align with the EU’s tightening requirements for carbon footprint and structural safety, giving European buyers a ready-to-qualify supply chain.
