Frequently Asked Questions (FAQ)

Q1: How do I choose the right bore size and pressure rating for my Плашечный превентор?

Bore size should match or exceed your largest casing OD plus clearance. For most land rigs, 7 1/16″ is the standard for 4-1/2″ to 5″ drill pipe operations. Pressure rating must exceed your maximum anticipated surface pressure (MASP). The 5,000 psi (5M) working pressure is adequate for most land drilling applications. For higher pressure wells, 10M or 15M rated BOPs are recommended. Always consult your well program and casing design before selecting.
