Critical Connections Demand Certainty

By Yvette Schmiz and Gord Britton, Integra Technologies |

Figure 1.  During tightening, hydraulic pressure load within a bolt should be uniformly and accurately applied to avoid gasket damage and other issues that can create leakage Common knowledge dictates that planning ahead ensures effective results, regardless of the task at hand. Controlling the process is essential to controlling the outcome. Operations in the chemical process industries (CPI) require accuracy and attention to detail, right down to some of the smallest elements — bolts. Delays, defects and accidents in the CPI can be avoided by improving the effectiveness and reliability of bolted joints. Many questions arise when considering bolt performance and maintenance. For instance, how often does one pay attention to the behavior of a stud bolt when tightening? How often should routine tightening checks be completed, and how does one know which tightening method is best for a specific application? Some of these issues can be addressed with an understanding of bolts’ behavior under various tightening methods. Bolted flanges are certainly not designed to leak, and simple procedures and maintenance routines exist to help prevent prolonged shutdowns, save on costs and improve overall safety.…
