Description

Guidelines described in this document apply to pressure-boundary flanged joints with ring-type gaskets that are within the circle enclosed by bolt holes.
Bolted flange joint assembly (bfja) guidelines described document apply pressure-boundary flanged joints ring-type gaskets entirely within circle enclosed bolt holes no contact outside circle. selection features suitable specific service need, may used develop effective procedures broad range sizes conditions normally encountered industry. guidance troubleshooting bfjas not providing leak-tight performance also provided (appendix p). pcc-1-2019 replaces previous edition, published 2013.  unique world addressing issues pressure vessel piping standards perspective. address subsequent advances gasket technology, bolting procedures, calculation methods enabled improvement integrity efficiency bolted-joint assembly.  assembles current industry best practice one easily-referenced location. appendix a, “training qualification assemblers”, example, provides establishing uniform criteria training qualifying personnel, well quality control program. addition, f, “alternative patterns”, adds faster will achieve equal better legacy methods. applying lessons learned offer significant benefits bfja safety, cost-reduction. intended assemblers, designers, supervisors, inspectors instructors industries employ boundary joints.
