It eliminates pipe ovality, uneven wall thickness and dimensional deviation after piercing and rolling, ensuring consistent outer diameter, roundness and straightness of OCTG pipes.<\/p>\n<p>Gracias a su accionamiento hidr\u00e1ulico de alta precisi\u00f3n y a los juegos de matrices de expansi\u00f3n modulares, proporciona una fuerza de expansi\u00f3n radial uniforme. Es compatible con aceros al carbono, aceros aleados y aceros de alta resistencia para OCTG, lo que permite la producci\u00f3n en serie con un rendimiento estable, una baja tasa de deformaci\u00f3n y una alta repetibilidad dimensional. Se adapta perfectamente a los procesos posteriores de tratamiento t\u00e9rmico, roscado y acoplamiento para cumplir con las normas API Spec 5CT.<\/p>\n<h3>Nuestras ventajas<\/h3>\n<ul>\n<li>\n<div><strong>Precise dimensional correction<\/strong><\/p>\n<div><\/div>\n<p>Uniform hydraulic expansion straightens pipe ovality, corrects uneven wall thickness and out-of-tolerance inner\/outer diameter after piercing and rolling, strictly matching OCTG dimensional tolerance required by API standards.<\/p><\/div>\n<div><\/div>\n<\/li>\n<li>\n<div><strong>Eliminate internal residual stress<\/strong><\/p>\n<div><\/div>\n<p>Relieve residual stress generated during tube piercing and hot rolling, effectively preventing pipe bending, distortion or cracking in subsequent heat treatment, threading and end upsetting processes.<\/p><\/div>\n<div><\/div>\n<\/li>\n<li>\n<div><strong>Improve roundness &amp; inner surface quality<\/strong><\/p>\n<div><\/div>\n<p>Smooth inner tube surface, eliminate indentations, wrinkles and local deformation; greatly boost concentricity, laying reliable foundation for high-precision threading and coupling assembly.<\/p><\/div>\n<div><\/div>\n<\/li>\n<li>\n<div><strong>Wide adaptability for OCTG specifications<\/strong><\/p>\n<div><\/div>\n<p>Flexibly fit various casing &amp; tubing OD ranges, compatible with multiple steel grades for J55, N80, P110 and other API 5CT OCTG products, easy specification switching for mixed batch production.<\/p><\/div>\n<div><\/div>\n<\/li>\n<li>\n<div><strong>Stable expansion uniformity &amp; high yield rate<\/strong><\/p>\n<div><\/div>\n<p>Full circumferential synchronous hydraulic expansion ensures consistent expansion deformation along entire pipe length; fewer rejected pipes, lowering production cost and improving finished product qualification rate.<\/p><\/div>\n<div><\/div>\n<\/li>\n<li>\n<div><strong>High automation &amp; easy operation<\/strong><\/p>\n<div><\/div>\n<p>Matched with automatic feeding and positioning, easy parameter adjustment; low maintenance cost, stable long-term continuous running suitable for high-volume seamless OCTG production lines.<\/p><\/div>\n<\/li>\n<\/ul>","protected":false},"featured_media":4064,"template":"","meta":{"_acf_changed":false},"product-category":[20],"class_list":["post-3620","product","type-product","status-publish","has-post-thumbnail","hentry","product-category-octg-production-line"],"acf":[],"_links":{"self":[{"href":"https:\/\/gh-petro.com\/es\/wp-json\/wp\/v2\/product\/3620","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gh-petro.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/gh-petro.com\/es\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gh-petro.com\/es\/wp-json\/wp\/v2\/media\/4064"}],"wp:attachment":[{"href":"https:\/\/gh-petro.com\/es\/wp-json\/wp\/v2\/media?parent=3620"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/gh-petro.com\/es\/wp-json\/wp\/v2\/product-category?post=3620"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
