Jianing Forging adopts proprietary forging processes and strict quality control systems to solve connection reliability challenges from the source, ensuring that every flange can withstand the long-term test of complex working conditions.
The tower flanges (wind turbine tower forged flanges) produced by Caring Forging use high-quality alloy steel as the base material, undergoing multiple forgings, heat treatments, and precision machining. The product is specially designed for onshore and offshore wind turbines, featuring high tensile strength, excellent low-temperature toughness, and stable dimensional accuracy. It is compatible with mainstream tower connection structures to support continuous operation of the entire turbine.
High-quality alloy steel is selected, and after three-stage ultrasonic testing, the internal defect rate is lower than the industry's general standard.
The forging ratio is sufficient, the fibers flow continuously, and the overall mechanical properties are uniform and reliable.
Equipped with dedicated tooling, with coaxiality and end face parallelism strictly controlled within set tolerances.
Supports customization of non-standard dimensions, materials, and surface anti-corrosion processes, seamlessly matching different tower segments.
This product is a customized item. The specific price should be calculated comprehensively based on flange specifications, material requirements, heat treatment grade, and order quantity. Please provide detailed requirements or drawings, and we will offer you a targeted quotation plan.
Jianing Forging provides full-process services from technology selection and process review to delivery tracking. During order execution, we proactively confirm key milestones with customers to help deliver products on schedule; After-sales service provides technical support and prompt handling of quality disputes, assisting customers in completing on-site installation and acceptance.
