Setting the Industry Standard

Historically the management of bolted flange joints has been subject to limited guidance compared with the welded joint. However as leaks become increasingly unacceptable by management teams and emissions targets are lowered, more industry guidance has gradually emerged to raise standards. 2013 proved to be a landmark year in this respect, with two major new standards published concerned with the assembly and management of bolted flange joints. ASME released an updated PCC-1-2013 Guidelines for Pressure Boundary Bolted Flange Joint Assembly and CEN (the European committee for standardisation) re-published EN1591 Part 4 with modifications as a standard now entitled Flanges and their Joints – Part 4: Qualification of Personnel Competency in the Assembly of the Bolted Connections of Critical Service Pressurized Systems.

The latest ASME release identifies the need to treat bolted flange joint assembly with similar quality assurance requirements to that of welded joints. Hydratight has long championed this approach, and has been at the forefront of driving industry standards in controlled bolting, flange management, and integrity assurance for more than 20 years. This has culminated in Hydratight becoming the world’s first ASME PCC-1-2013 qualifying organization, following an independent audit by Lloyds Register Energy.

Hydratight’s key areas of credibility include the following:-


  •  

    Launched a Hydratight Joint Integrity College to deliver training and qualification that meets or exceeds the requirements of ASME PCC-1-2013 guidance to our own technicians, engineers and managers.
