Three mud pumps on site change valve bodies and seats every 400 hours, and screens run about 40 pieces a week.
Looking at onshore Niger Delta blocks, local suppliers can only do seats and some screens; the material certificate lists ordinary alloy steel without a hardness curve.
Looking at onshore Niger Delta blocks, which tests should alternatives pass, and which pressure-retaining parts must stay with the original or authorised channel?

What we see at Port Harcourt is that test hardness and dimensional tolerance on seats first, then inspect after 200 hours; do not swap the whole batch at once.

What we see at Port Harcourt is that on screens, check weave and tension dimensions; correct aperture with wrong tension halves the life.

In Port Harcourt, do not substitute pressure-retaining items such as safety valves and BOPs; missing certificates affect insurance and release at acceptance.
