Wind power generation bolt 

Wind power generation bolts are important fasteners used in wind power generation units, featuring high strength and corrosion resistance. They are mainly used for fixing the tower frame and connecting the pitch flange.

Types of wind power bolts

Wind power bolts are mainly classified into the following categories:

Wind power tower bolts: Used to fix the tower of the wind power generator, usually made of high-strength double-ended bolts, with strength grades generally ranging from 8.8 to 12.9.

Wind power blade bolts: Used to connect the wind power blades to the hub, requiring good fatigue resistance and corrosion resistance.

Wind power main bolts: The most important bolts in wind power generators, usually requiring the installation of nearly 1,500 bolts, with high strength requirements. Common materials are alloy steel and stainless steel.

Materials and strength grades

Materials: Wind power bolts commonly use carbon steel, alloy steel, and stainless steel. Alloy steel bolts typically have a strength of 8.8 or 10.9 grades, while stainless steel bolts have excellent corrosion resistance and are suitable for humid or corrosive environments.

Strength grades: Wind power bolts typically have strength grades of 8.8, 10.9, and 12.9, with the numbers representing the multiple of tensile strength. For example, an 8.8-grade bolt has a tensile strength of 800 MPa and a yield strength ratio of 0.8.

Application and importance

Wind power bolts play a crucial role in wind power generation units, ensuring reliable connections of various components and directly related to the safety performance of wind power generation units. With the development of the wind power industry, the demand for high-strength, corrosion-resistant wind power bolts is increasing, promoting the advancement of related technologies and market development. Conclusion

Wind turbine bolts are indispensable fasteners in the wind power generation industry, featuring high strength and corrosion resistance. They are widely used in various parts of wind turbine units. With the continuous advancement of technology, the performance and application scope of wind turbine bolts will further improve in the future.
