It can complete accurate full-length wall thickness measurement alongside flaw detection in one inspection cycle.<\/div>\n<div><\/div>\n<div>All inspection processes and data logging fully comply with authoritative API 5CT and API 5L standards, effectively satisfying strict quality control standards for OCTG manufacturers across the global oil and gas sector.<\/div>\n<h3>Principe de fonctionnement<\/h3>\n<p>The machine operates on the\u00a0<strong>ultrasonic pulse-echo technique<\/strong>. High-frequency ultrasonic waves (2\u20135 MHz) are generated by piezoelectric probes and transmitted into the pipe wall via\u00a0<strong>water-coupling<\/strong>.<\/p>\n<ul>\n<li><strong>No defect<\/strong>: Ultrasound travels through the wall and reflects from the inner surface, producing a\u00a0<strong>back-wall echo<\/strong>.<\/li>\n<li><strong>With defect<\/strong>: Waves reflect earlier at discontinuities (cracks, inclusions, laminations), generating a\u00a0<strong>defect echo<\/strong>\u00a0before the back-wall signal.<\/li>\n<li>The system calculates\u00a0<strong>defect depth, size, and position<\/strong>\u00a0based on echo time and amplitude, enabling accurate, repeatable, and high-speed inspection.<\/li>\n<\/ul>\n<h3>Our Core Advantages<\/h3>\n<ul>\n<li>High\u2011precision detection for pipe body, thread and coupling, effectively identifies cracks, porosity, inclusions and other hidden defects conforming to API\u20115CT standards.<\/li>\n<li>High\u2011speed on\u2011line non\u2011destructive testing, matches full\u2011line production rhythm without interrupting continuous OCTG manufacturing.<\/li>\n<li>Multi\u2011mode integrated inspection: combine ultrasonic, magnetic particle and eddy\u2011current testing to cover surface and subsurface flaws.<\/li>\n<li>Automatic data recording &amp; real\u2011time report generation, traceable inspection records for quality audit and customer review.<\/li>\n<li>Intelligent alarm &amp; automatic marking for defective tubes, reduces manual misjudgment and lowers human\u2011error risk.<\/li>\n<li>Stable performance for long\u2011hour heavy\u2011duty industrial operation, suitable for harsh pipe\u2011making workshop environment.<\/li>\n<li>Easy integration with existing OCTG production line, minimal modification required for on\u2011site installation &amp; commissioning.<\/li>\n<li>Low maintenance cost, supports long\u2011term continuous running to guarantee overall line productivity.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>","protected":false},"featured_media":4226,"template":"","meta":{"_acf_changed":false},"product-category":[20,47],"class_list":["post-4233","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\/fr\/wp-json\/wp\/v2\/product\/4233","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gh-petro.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/gh-petro.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gh-petro.com\/fr\/wp-json\/wp\/v2\/media\/4226"}],"wp:attachment":[{"href":"https:\/\/gh-petro.com\/fr\/wp-json\/wp\/v2\/media?parent=4233"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/gh-petro.com\/fr\/wp-json\/wp\/v2\/product-category?post=4233"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
