定义
Mounting bolts are precision-engineered fasteners used to attach agitator blades to the shaft in chemical reactors. They must maintain secure connections under dynamic loads, thermal cycling, and exposure to aggressive chemicals while preventing leakage and ensuring operational safety.
工作原理
These bolts work by applying clamping force through torque, creating friction between the blade hub and shaft to resist rotational and axial forces. Proper preload prevents loosening from vibration and thermal expansion, ensuring stable blade alignment for efficient mixing.
材料
Stainless steel (AISI 316/316L) or nickel alloys (e.g.Hastelloy C-276) for corrosion resistanceheat-treated alloy steel (e.g.ASTM A193 B7) for high-strength applicationscoatings like PTFE or zinc-nickel for additional protection.
Length
50-200 mm
Thread Size
M12 to M30
Tensile Strength
800-1000 MPa
Temperature Range
-50°C to 400°C
Corrosion Resistance
CRES 316 minimum for chemical exposure
Torque Specification
As per manufacturer's guidelines (e.g., 70-300 Nm)
标准
ISO 898-1DIN 931ASME B18.2.1

常见问题

What materials are best for mounting bolts in corrosive chemical environments?

Stainless steel (AISI 316/316L) or nickel alloys like Hastelloy are recommended for their resistance to acids, bases, and chlorides, preventing degradation and failure.

How often should mounting bolts be inspected in a chemical reactor?

Inspect during routine maintenance every 3-6 months, checking for corrosion, wear, and torque loss, with replacement as needed based on operational conditions.
