... Abstract This paper uses finite element models of an API flange to consider the suitability of the maximum bolt preload permitted by API 17D, 67% of the bolt’s material yield stress [1]. The flange was reviewed under ambient temperature, and under a large thermal gradient. Pressure and external...

... Abstract Bolted flanges are widely used to connect pipelines in many industries. To assure sealability of a flange, generation of proper preloads in the bolts during the assembly process is critical. However, in the existing standard practice, identical torques are typically applied to all...

... Abstract Over the past two years, the accuracy and repeatability of equipment used to assemble bolted flanged joints have been studied, and progress has been reported in past papers. One of the findings has been that pneumatic torque wrenches demonstrated a broader plus/minus range on bolt...

... Abstract Bolted flange connections are heavily used within the chemical production/processing, transportation, marine, and power generation industries to contain processes while minimizing leaks. These leaks could cause unsafe working conditions, environmental hazards, and/or loss of product...
