Mechanical Joint Integrity
Critical Bolted Joints
Hevï Technology's Technicians travel the world to address critical bolted joints on high-value plant components. Central to this service is the company's extensive use of Ultrasonic Bolt Load Analysis.
The Danger of "Torque"
Assembly torque is merely an indication of resitance to a wrench's input force. Even with fully calibrated tools, "torque" has limited relationship to a fastener's preload. Reliance on torque is a leading cause of bolt failure, joint leakage, production loss and the need for often costly plant repair or replacement.
The Safety of "Elongation"
A fastener's elongation is directly related to its load. Thus, by measuring the stretch of a fastener, required bolt preload can be attained with confidence. Hevï Technology utlizes highly-specialized ultrasonic instrumentation to determine bolt base-line length and then, elongation. The resultant data are used to "tune" each fastener into spec.
The Reassurance of "Experience"
Sophisticated ultrasonic bolt load technology was originally developed for the US space program. Today's instruments have become "relatively" easier to use. Nonetheless, inexperience can garner a false sense of security. Technician proficiency is absolutely critical for reliable results. With almost twenty years experience in this field, Hevï Technology provides peace-of-mind to the company's clients.
