Material Inspection<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first actual inspection work on the pressure vessel is the raw materials inspection. Based on the ASME Code, providing&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/what-is-the-material-test-report-mtr-mill-test-report\/\" target=\"_blank\" rel=\"noopener\">material test reports<\/a>&nbsp;for&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/pressure-vessel-plate\/\" target=\"_blank\" rel=\"noopener\">pressure vessel plate<\/a>&nbsp;is mandatory. For other components, the marking inspection will be enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But if the purchase order has mandated the MTR to be provided for all components, such as nozzle pipes, fittings, etc., then the manufacturer needs to provide them as well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As mentioned above, the original or authenticated copies of mill certificates for plates normally are available at the manufacturer&#8217;s premises.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/industrial-third-party-inspection\/\" target=\"_blank\" rel=\"noopener\">third party inspector<\/a>&nbsp;examines these certificates for compliance with specifications, and where appropriate, drawings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The review includes checks on:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Certificate No.<\/li><li>Heat or Cast No.<\/li><li><a href=\"https:\/\/ptrotek.wordpress.com\/what-is-the-material-test-report-mtr-mill-test-report\/\" target=\"_blank\" rel=\"noopener\">Chemical Composition<\/a>.<\/li><li><a href=\"https:\/\/ptrotek.wordpress.com\/what-is-the-destructive-testing\/\" target=\"_blank\" rel=\"noopener\">Mechanical Properties<\/a>.<\/li><li>Heat Treated Condition.<\/li><li>NDE Applied and Results.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Then the inspector witnesses the plate material identification on the certificates against the plate marking. It is also necessary to check the identification with the pressure vessel drawing datasheet, material list and other specifications as appropriate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The transfer identification to cut off plates also is checked.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Visual inspections for surface finish and probable defects are done and dimensional compliance with specification also needs to be controlled.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the third party inspector carries out the material inspection, then provides the inspection visit report (IVR), the report contains the following items:<br><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Confirmation of satisfactory document review<\/li><li>Record of the endorsement of certification reviewed\/witnessed<\/li><li>Record of all&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/what-is-the-nonconformity-report-ncr\/\" target=\"_blank\" rel=\"noopener\">non-conformities<\/a><\/li><li>Record of any tests witnessed and the result<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Third Party Inspection for Pressure Vessel &#8211; Fabrication<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the pressure vessel raw material inspection is carried out, and the results were satisfactory or non-conformities were closed by remedial action, then the pressure vessel manufacturer will start fabrication.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The third party inspector checks the following points on the pressure vessel, based on the&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/inspection-and-test-plan-for-pressure-vessel\/\" target=\"_blank\" rel=\"noopener\">inspection and test plan (ITP)<\/a>, which has already been agreed upon between the purchaser and the pressure vessel manufacturer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The inspection scope is determined in the ITP. Some purchasers prefer to have stringent controls and assign the TPI for more \u201c<a href=\"https:\/\/ptrotek.wordpress.com\/inspection-and-test-plan\/\" target=\"_blank\" rel=\"noopener\">hold or witness points<\/a>\u201d for inspection and test activities, and some others prefer less \u201chold or witness points\u201d and assign the TPI much more work in the \u201creview document.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This depends in the inspection budget, which purchasers assign for inspection. Much more inspection will have a much larger cost and less risk, and conversely, less inspection will have less cost but more risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Third Party Inspection for Pressure Vessel &#8211; Preparation for Welding<\/strong><br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The third party inspector carries out the visual and dimensional check to ensure compliance with WPS and other specifications.
