Overview of Bolts

A Bolt is a threaded fastener that has an external male thread used in conjunction with nuts to attach separate pieces of equipment together. Bolts are often used to hold together sections of pipelines, piping, boilers or other equipment. In industrial applications it is extremely important for bolts to be tightened properly and inspected regularly. Because bolt failure can lead to significant process safety incidents, operators should take measures to ensure they have implemented an effective joint integrity management program.

ASME PPC-1 provides guidelines for pressure boundary bolted flange joint assemblies and can be used to develop joint assembly procedures for a broad range of services.
