摘要: A coupling apparatus and a method are for connecting two drill-pipe sections in a string of drill-pipe sections joined together by tool joints. The coupling apparatus comprises: a first pipe with a first end portion and a second end portion, the first end portion being provided with a tool joint for connection to a drill-pipe section; a second pipe with a first end portion and a second end portion, the first end portion being provided with a tool joint for connection to a drill-pipe section.

摘要: A drainage device is for a tubular, telescopic pipe-landing unit having a through pipe bore partially formed of a center pipe extending from an upper end portion of an outer pipe-landing section and with a free end in through an upper end portion of an inner pipe-landing section, which is axially movable in the outer pipe-landing section. The center pipe has a fluid-communication opening arranged for pressure equalization between the pipe bore and an annulus between the center pipe and the outer pipe-landing section. The annulus has a drain passage arranged to be opened by the axial movement of the inner pipe-landing section into the outer pipe-landing section away from an extended, operative position, in which an abutment portion on the upper end portion of the inner pipe-landing section is resting sealingly against a seat portion on a lower end portion of the outer pipe-landing section.
