Shanxi Jianing Forging produces a full range of flanges, including plate-type flat welding, neck butt welding, stainless steel, carbon steel, wind turbine tower tubes, pressure vessel flanges, blind plates, figure-8 blind plates, and threaded special-shaped flanges, all customizable with multiple sealing surface types, and a full set of production qualifications for stable supply.
During long-term operation, fatigue fracture and sealing failure at flange connections in wind turbine blades are common industry challenges, directly affecting unit safety and operation and maintenance costs. The blade flanges provided by Canin Forging are strictly controlled from materials to processes, helping each set of flanges stably transmit loads under harsh working conditions, effectively reducing the risk of failure.

Blade flanges are the key connecting components between wind turbine blades and hubs, and must withstand complex alternating loads. Jianing Forging focuses on the research, development, and production of wind power supporting flanges, using high-quality alloy steel formed through fine forging processes. The products have high strength, good toughness, stable dimensional accuracy, and can be adapted to various mainstream wind turbine blade models.
Made of relatively high-strength alloy steel, it undergoes multiple heat treatment processes and exhibits excellent overall mechanical properties
Fine forging process with rational flow distribution and long fatigue life
Strict dimensional tolerance control ensures reliable installation and coordination, reducing on-site adjustments
The surface anti-corrosion treatment process is mature, adaptable to various environments both offshore and onshore
Targeted development can be made based on the blade manufacturer's interface drawings, allowing flexible matching
Blade flanges are non-standard custom products, and the actual price is affected by factors such as material, specifications, quantity, and surface treatment requirements. We offer one-on-one technical matching and relatively accurate quotation services. We welcome you to provide drawings or technical parameters for customized solutions.
From drawing review to finished product delivery, we provide full-process technical support
We strictly implement the ISO quality management system, with each batch accompanied by material reports and inspection records
Delivery cycles are controllable, and urgent orders can be negotiated for expedited production
After-sales issues will be addressed within 24 hours, with technical staff arranging on-site service if necessary
