Overview<\/h1>\n

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

Our Ultrasonic Flaw Inspection Machine<\/a> for Drill Pipes and Drill Collars is a fully automatic CNC-controlled NDT system engineered for 100% volumetric inspection of OCTG products including drill pipes and drill collars.<\/div>\n
<\/div>\n
Outfitted with high-performance ultrasonic transducer arrays, it delivers highly sensitive detection of longitudinal cracks, transverse fractures, inclined flaws and laminar delaminations. The equipment performs accurate full-length wall thickness measurement simultaneously with flaw detection within a single inspection pass.<\/div>\n
<\/div>\n
All inspection procedures and data logging fully comply with official API 5CT and API 5L standards, perfectly meeting strict quality control specifications for OCTG manufacturers across the global oil and gas sector.<\/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>","protected":false},"featured_media":4223,"template":"","meta":{"_acf_changed":false},"product-category":[20,47],"class_list":["post-4238","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\/4238","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\/4223"}],"wp:attachment":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/media?parent=4238"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/product-category?post=4238"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
