Overview<\/h2>\n

\"\" \"\" \"\" \"\"<\/p>\n

Our Welded Pipe Phased Array Ultrasonic Testing PAUT Machine<\/a> is a fully automatic CNC-controlled NDT system developed for 100% volumetric inspection of seamless tubes, ERW pipes, oil casings and production tubing.<\/div>\n
<\/div>\n
Equipped with high-performance ultrasonic transducer arrays, it provides high-sensitivity detection of longitudinal cracks, transverse fractures, inclined defects and laminar delaminations. It can realize precise full-length wall thickness measurement synchronously with flaw detection in a single inspection cycle.<\/div>\n
<\/div>\n
All inspection workflows and data logging fully comply with official API 5CT and API 5L standards, well meeting stringent quality control requirements for OCTG manufacturers in the global oil and gas industry.<\/div>\n

Working Principle<\/h2>\n

The machine operates on the\u00a0ultrasonic pulse-echo technique<\/strong>. High-frequency ultrasonic waves (2\u20135 MHz) are generated by piezoelectric probes and transmitted into the pipe wall via\u00a0water-coupling<\/strong>.<\/p>\n

    \n
  • No defect<\/strong>: Ultrasound travels through the wall and reflects from the inner surface, producing a\u00a0back-wall echo<\/strong>.<\/li>\n
  • With defect<\/strong>: Waves reflect earlier at discontinuities (cracks, inclusions, laminations), generating a\u00a0defect echo<\/strong>\u00a0before the back-wall signal.<\/li>\n
  • The system calculates\u00a0defect depth, size, and position<\/strong>\u00a0based on echo time and amplitude, enabling accurate, repeatable, and high-speed inspection.<\/li>\n<\/ul>\n<\/div>","protected":false},"featured_media":4217,"template":"","meta":{"_acf_changed":false},"product-category":[20,47],"class_list":["post-4235","product","type-product","status-publish","has-post-thumbnail","hentry","product-category-octg-production-line","product-category-ultrasonic-flaw-detection-machine"],"acf":[],"_links":{"self":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/product\/4235","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/media\/4217"}],"wp:attachment":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/media?parent=4235"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/product-category?post=4235"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
