| 摘要 | A wellhead assembly includes first and second wellhead members. An annular lock groove is located on an inner or an outer diameter surface of the first wellhead member. An annular lock ring is supported on an annular shoulder of the second wellhead member and is radially moveable between an unset position and a set position where a locking profile of the annular lock ring engages the annular lock groove. The second wellhead member is positioned concentrically with the first wellhead member, defining an annulus between the first and second wellhead members. An energizing ring is positioned in the annulus and axially movable between an unengaged position and an engaged position. The energizing ring has an engaging portion with a corrugated shape in cross section that is interference fit between the annular lock ring and the second wellhead member when the energizing ring is in the engaged position. | ||||||
