Component Specifications

Definition
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.
Working Principle
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.
Materials
Stainless steel (AISI 316/316L) or nickel alloys (e.g., Hastelloy C-276) for corrosion resistance; heat-treated alloy steel (e.g., ASTM A193 B7) for high-strength applications; coatings like PTFE or zinc-nickel for additional protection.
Technical Parameters
  • 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)
Standards
ISO 898-1, DIN 931, ASME B18.2.1

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
