All components comply with API 16A and API 7K standards, making them suitable for critical well control and drilling operations where safety and reliability are paramount.

Maintenance Suggestions

Based on decades of on-site maintenance experience, our engineers provide practical, easy-to-follow suggestions to extend the service life of spare parts and avoid common faults: For annular BOP packing units (3131189-02), inspect for wear and leakage every 300 working hours; if the packing is compressed by more than 3mm, replace it immediately—avoid over-tightening the packing, as it will cause excessive friction and damage the BOP ram. For casing tong seals (103311-001), clean the seal groove before installation to remove mud and debris; replace the seal every 500 working hours, even if no leakage is found, as rubber degrades over time. For Parker Hannifin clutch assemblies (270XAAKP-D4XK), check the clutch gap every 400 working hours (standard gap 0.8-1.2mm); add the recommended lubricating oil (ISO VG 32) to the clutch mechanism to prevent dry friction. For filters (250034-085, 02250048-734), replace the filter element every 800 working hours; if the pressure differential switch (02250050-154) triggers an alarm (pressure difference exceeding 0.7 bar), replace the filter immediately to avoid damaging the hydraulic pump. For pulsation dampener bladders (5773), check the pre-charge pressure every 6 months (standard 1,000 PSI); if the pressure drops by more than 100 PSI, recharge it to prevent bladder damage. A key reminder: When replacing BOP components, ensure all parts are clean and free of debris, as even small particles can cause seal failure and well control risks.
