High-Strength Double End Studs

High-Strength Double End Studs are special fasteners with threaded ends and a smooth center. They are designed to solve structural connection problems involving deep holes, confined spaces, or periods of disassembly. These High-Strength Double End Studs are widely used in petrochemical reactors, high-pressure flanges, large diesel engine cylinder heads, compressor housings, and wind turbine gearboxes. Compared to single-ended bolts, High-Strength Double End Studs do not wear down the threads of the base material during disassembly, and can be adapted to different connection thicknesses by adjusting the thread lengths at both ends. Under high-temperature or alternating temperature conditions, High-Strength Double End Studs, when used with special lubricating or heat-insulating gaskets, can effectively control preload decay caused by thermal stress.

Produkto funkcijos ir taikymas

Flexible double-thread design: The screw-in and fastening ends can be designed with different lengths, different pitches (coarse/fine), and even different precision grades. The fastening end can be freely configured according to the total thickness of the connected parts.

Excellent anti-relaxation properties: Utilizing a quenching and tempering process, it exhibits low creep and stress relaxation tendency under high temperatures and alternating loads, making it suitable for pressure vessels and high-temperature pipeline flanges.

Reliable preload control: Both ends of the thread can be tightened using a precision torque wrench or hydraulic tensioner. The tightening end can be machined with a cylindrical locating surface (or a slip-on flange structure) with high parallelism, facilitating synchronous preload using a tensioner.
