| 摘要 |
A tubular and tubular connection for joining adjacent tubulars of a tubular string for passage of fluid therethrough is provided. The tubular connection includes a pin end at an end of a first of adjacent tubulars and a box end at an end of a second of the adjacent tubulars. The pin end has an outer locking surface. The box end has a plurality of fingers at an end thereof with slots therebetween. The fingers are selectively extendable for placement about the pin end of the first of the adjacent tubulars. The fingers having an inner locking surface for interlocking engagement with the outer locking surface of the pin end whereby loads are distributed between the adjacent tubulars. |
