1 Scope
1.1 OBJECTIVE
The objective of this publication is to provide owners and users of equipment listed below guidelines for inspection, maintenance, repair, and remanufacture procedures that may be utilized to maintain serviceability of the covered equipment.
This recommended practice covers the following drilling equipment:
a. Rotary tables.
b. Rotary bushings.
c. Rotary slips.
d. Rotary hoses.
e. Slush pump components.
f. Drawworks components.
g. Spiders not capable of use as elevators.
h. Manual tongs.
i. Safety clamps not used as a hoisting device.
1.2 PROCEDURE DEVELOPMENT
The owner or user, together with the manufacturer should jointly develop and update inspection, maintenance, repair, and remanufacture procedures consistent with equipment application, loading, work environment, usage, and other operational conditions. These factors may change from time to time as a result of new technology, equipment history Product improvements, new maintenance techniques, and change in service conditions.
