Bolt Tensioning Standards

1.1 This specification covers one style of heat treated, alloy steel, tension control bolt-nut-washer assemblies, also referred to as "sets," having a tensile strength of 200 to 215 ksi. These assemblies are capable of developing a minimum predetermined tension when installed...

This part of EN 10319 specifies the test method for determining the stress relaxation of bolts tensioned in bolted joint models subjected throughout the test to overall constant strain and constant temperature conditions.

Introduction: Lap-Joint Flanges (LJF) have been used for decades. The typical polyethylene flange adapter with loose LJF is also known as a Van-Stone Flange joint. The HDPE flanged joint assembly is an engineered pressure containment connection subject to diverse forces. While simple in appearance,...
