Pressure Vessel Components
Quality Control Procedures Prior to shipment, all manufactured components undergo thorough quality control inspection to ensure conformance to ASME codes and / or other international codes and standards. Upon request, we will also perform inspections to ensure compliance to specific customer requirements. Where applicable, pressure vessel heads, shells and other components are supplied with a Certificate of Compliance showing type, size, material type, order numbers, heat numbers and minimum thicknesses. All material supplied from our plate inventory is checked for proper stamping of material type. Heat numbers are checked against original Mill Test Certificates on file to ensure compliance. Mill Test Certificates are provided at time of shipment. For heads, the Certificate of Compliance also includes visual inspections done on heads (ie. roundness, form conformity, surface conditions, etc.), and certifies that the heads are made to meet the applicable standards, such as: - ASME Sec. 1, PG-29 - ASME Sec. VIII, Div. 1, UCS-79(d), UG-80(b), UG-81 - ASME Sec. VIII, Div. 2, 6.1.2.1 & 4.3.2.2 - Registered Weld Caps to ASME SA234 WPB / ANSI B16.9 - Other international codes and standards All welded components (ie. heads, shells, fittings, pipings) are welded using certified and approved welding procedures and the welders / operators are qualified to ASME code Sec. IX. When required, partial data forms, Certificates of Compliance, and Jurisdictional Affidavits shall be supplied where applicable as follows: - ASME Sec. 1, P4 Forms - ASME Sec. VIII, Div. 1, U2 Forms - ASME Sec. VIII, Div. 2, A2 Forms - ASME SA-671, ASME SA-672 - CSA Z245.1 - CSA Z662 - SA-234, SA-420 - CSA Z245.11 - ASME Pressure Piping (PP) - ASME B31.1 & B31.3 |
