Hydraulic Tensioning v. Torque: Design Considerations for Turbo-Machinery Equipment

Riverhawk, Webinar, Free


OEMs and end users in the turbomachinery industry are routinely faced with tooling and bolting challenges associated with traditional torqueing methods.  Insufficient and non-uniform load distribution, insufficient gasket sealing, stud thread galling, and torque spikes all contribute to costly, time-consuming turnarounds.

These issues are common in rotating and reciprocating equipment in numerous industries including power generation, petrochemical, oil & gas, nuclear, mining, steel and others.

Hydraulic tensioning systems, available in both standard and custom designs, provide accurate, precise and repeatable performance, saving users both time and money.  The Hydraulic Tensioning System is suitable for most applications including high temperature, limited spot face, high residual load applications and can be retrofitted to existing installation requirements.

This informative webinar, presented by Patrick McCormack, Business Development Manager of Riverhawk Company, will present several tensioning and joining solutions highlighting:

  • Tension v. Torque

    • How a Hydraulic Tensioning System will eliminate stud galling and reduce disassembly and reassembly time while extending hardware longevity

    • The use of simultaneous hydraulic tensioning of studs to avoid problems of insufficient loading such as inadequate flange closure

  • Rotational Equipment Challenges

    • Effective use of torque couplers on compressors, gearboxes, motors and fans to eliminate keys, splines tapered shafts and heat at assembly

    • Avoiding torque-related events such as spikes and torsional vibrations on critical equipment using effective shaft joining technologies

    • Eliminating rotational torque vibrations

Attendees will be free to pose additional questions which will be addressed at the webinar conclusion.

This webinar can help you in making informed decisions concerning new or retrofit bolting and tooling alternatives.
