API SPEC 7K

Abstract

This specification provides general principles and specifies requirements for design, manufacture, and testing of new drilling and well-servicing equipment and of replacement primary load-carrying components manufactured subsequent to the publication of this specification. <br>This specification is applicable to the following equipment: <br>a) rotary tables; <br>b) rotary bushings; <br>c) standard rotary slips designed for use in standard rotary bowls with a 33.333 cm/m (4 in./ft) API taper; <br>d) nonstandard rotary slips without a taper of 33.333 cm/m (4 in./ft) for use in manual spiders as described in Item i); <br>e) high-pressure mud and cement hoses; <br>f) piston mud-pump components; <br>g) drawworks components; <br>h) manual spiders that use standard rotary slips as described in Item c) that are not capable for use as elevators and are installed on or above the master bushing/rotary table; <br>i) manual spiders that use nonstandard rotary slips not having a taper of 33.333 cm/m (4 in./ft) not capable of use as elevators, and installed on or above the master bushing/rotary table; <br>j) spring, pneumatic, or hydraulic spiders with integral slips not capable for use as elevators and are installed on or above the master bushing/rotary table; <br>k) spring, pneumatic or hydraulic spiders with integral slips not capable for use as elevators and are installed in, or partly in, the rotary table; <br>l) manual tongs; <br>m) safety clamps not used as hoisting devices; <br>n) power tongs, including spinning wrenches; <br>o) blowout preventer (BOP) handling systems; <br>p) pressure-relieving devices for high-pressure drilling fluid circulating systems; <br>q) snub-lines for manual and power tongs.
