Overview<\/h2>\n

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

Our Single Girder Gantry Ultrasonic Pipe Testing Machine<\/a> is a fully automatic CNC-driven NDT solution engineered for 100% full volumetric inspection of seamless and ERW oil pipes, casings and production tubing.<\/div>\n
Equipped with high-performance ultrasonic transducer arrays, it achieves high-sensitivity detection of longitudinal cracks, transverse fissures, oblique defects and laminar delaminations. In a single inspection run, it also performs precise full-length wall thickness measurement simultaneously.<\/div>\n
All inspection procedures and data recording fully adhere to authoritative industry standards API 5CT and API 5L, reliably meeting rigorous quality control requirements of OCTG manufacturers worldwide in the 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>","protected":false},"featured_media":4213,"template":"","meta":{"_acf_changed":false},"product-category":[20,47],"class_list":["post-4232","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\/4232","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\/4213"}],"wp:attachment":[{"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/media?parent=4232"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/gh-petro.com\/pt\/wp-json\/wp\/v2\/product-category?post=4232"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
