API Spec 7K PDF

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.
