Can non-original parts be used for replacement?

It is not recommended. Original parts (matching the provided part numbers) meet API Spec 7K and SJ Petro ZJ40 rig design standards, ensuring compatibility and safety. Non-original parts may cause structural mismatch or premature failure.

2

What is the recommended inspection cycle for these parts?

For rotating parts (bearings, sheave) and fasteners (bolts, studs), inspect weekly; for structural parts (supports, angle steel), inspect monthly; conduct comprehensive inspection and key part replacement semi-annually.
