Overview<\/h2>\n

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

CNC Automatic Medium and Heavy Plate Ultrasonic Testing Machine<\/a> is a fully automatic CNC-controlled NDT system engineered for 100% volumetric inspection of assorted steel plates used for OCTG production and other industrial applications.<\/div>\n
<\/div>\n
Equipped with high-performance ultrasonic transducer arrays, this system achieves highly sensitive detection of longitudinal cracks, transverse fractures, inclined flaws and internal laminar delaminations. It executes precise full-length plate thickness measurement simultaneously with flaw detection within one inspection pass.<\/div>\n
<\/div>\n
All inspection workflows and data logging fully comply with stringent API 5CT and API 5L specifications, meeting strict quality control requirements for OCTG manufacturers throughout the global oil and gas sector.<\/div>\n
\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":4230,"template":"","meta":{"_acf_changed":false},"product-category":[20,47],"class_list":["post-4240","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\/4240","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\/4230"}],"wp:attachment":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/media?parent=4240"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/product-category?post=4240"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
