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. This specification is applicable to the following equipment: a) rotary tables; b) rotary bushings; c) standard rotary slips designed for use in standard rotary bowls with a 33.333 cm/m (4 in./ft) API taper; 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); e) high-pressure mud and cement hoses; f) piston mud-pump components; g) drawworks components; 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; 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; 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; 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; l) manual tongs; m) safety clamps not used as hoisting devices; n) power tongs, including spinning wrenches; o) blowout preventer (BOP) handling systems; p) pressure-relieving devices for high-pressure drilling fluid circulating systems; q) snub-lines for manual and power tongs.
