ASME PCC-1, Guidelines for Pressure Boundary Bolted Flange Joint Assembly (BFJA), is a standard created and published by the American Society of Mechanical Engineers (ASME). Published in November of 2013, PCC-1 replaces the first edition, which was published in 2000.
This standard applies to pressure-boundary flanged joints with ring-type gaskets that are entirely within the circle enclosed by the bolt holes and with no contact outside the circle. The guidelines within the standard may also be used to develop joint assembly procedures for a broad range of sizes and service as well. Guidance on troubleshooting BFJAs not providing leak-tight performance is also provided in this document.

Joint integrity management remain at the top of many operators’ priority list. The discipline considers risk and drives safety to ensure we learn necessary lessons from past catastrophic failures, such as the Piper Alpha explosion in 1988, where leaking gas condensate ignited and killed 167 of the 229 people on board the offshore rig.

Large scale capital projects present a myriad of challenges for owner-users in the oil and gas and petrochemical industries. Budgets are constantly being stretched and project deadlines are often exceeded. One area that deserves attention from all parties involved is joint integrity management.

With the increasing demand for oil, gas, and petrochemical products in a highly competitive market, products and services irrespective of their origin must satisfy customer quality requirements. Additionally, the needs to ensure quality control and regulatory compliance are now more scrutinized and critical than ever.

In November 2013, ASME released its updated PCC-1 guidelines for pressure boundary bolted flange joint assemblies. Contained within the document is Appendix A, which represents a major change from the previous 2010 release and is considered to be one of the most critically important changes for BFJA technicians, operators, and other industry professionals.

Joint integrity programs (JIP) should be an integral part of every refinery, petrochemical, production, or other industrial-complex facility operations.
Owners and operators of complex equipment and facilities need tools to manage the life of their assets. Rigorous inspection is needed to minimize the risk of equipment failure and meet regulatory requirements. It is critical to know...

If necessity is the mother of invention, then the American Society of Mechanical Engineers (ASME), the Occupational Safety and Health Administration (OSHA), and the Environmental Protection Agency (EPA) are the parents of guidelines, standards, and regulations that help keep industrial operations safe for humans and the environment.

Leakage of pressure vessel and piping bolted joints in refineries is an unnecessary hazard, with high associated cost, that can be easily rectified using currently available technology. There have been advances in gasket testing technology in recent years that have allowed great improvements to be made in the specification of gaskets for refinery applications. This minimizes the likelihood of joint leakage and results in reduce operating cost. In addition, there have also been advances in joint assembly procedures that have enabled significant reduction in joint assembly times, while resulting in a better final gasket stress distribution and therefore lower likelihood of leakage.
