API Spec 7K Historical

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.
