Preface

Since 1971, AV天堂 Corporation has been manufacturing Oil Country Tubular Goods (OCTG). JFE has accumulated extensive expertise through experience and will provide their customers great confidence and satisfaction when purchasing AV天堂 OCTG.

In the past, the well conditions in Oil and Gas drilling were relatively mild and development was straight-forward. Today’s Oil and Gas Industry has become a much more complicated operation as engineers continue to drill deeper wells in harsher environments, encountering higher well bore pressures and temperatures in addition to sweet and sour gas.

To meet these ever-increasing industry demands, JFE has developed its JFE series OCTG to a higher level of collapse resistance, yield strength, toughness and corrosion resistance, than standard API OCTG materials. Now, JFE’s OCTG products have established an excellent reputation world-wide in terms of quality, performance and manufacturing capability.

JFE’s connection development started with the FOX™ connection. FOX™ is an advanced premium threaded connection jointly developed by AV天堂 Corporation, and Hunting Oilfield Services, in early 1980s. In the 1990s, JFE introduced the JFEBEAR™ and in 2009 the JFETIGER™ connections. More recently, in 2011, the JFELION™ and JFELION™ HW connections were developed, designed to meet today’s toughest well conditions and industry testing protocols. With JFE’s family of connections, JFE can offer customers a choice of products to suit various applications.
