Closing plate 320×130

High-strength steel (Q235B); size 320×130mm; surface anti-corrosion paint; installed on the guiderail ends to seal open areas, prevent debris and drilling fluid from entering the framework, and reinforce end structural stability.

1. Corrosion from drilling fluid and moisture accumulation on the surface; 2. Deformation from accidental impact during BOP handling or rig maintenance; 3. Weld seam separation from vibration during rig transportation.

1. Clean weekly to remove debris and drilling fluid; 2. Inspect monthly for deformation and weld seam separation; repair if needed; 3. Use protective padding around the closing plate during BOP handling to avoid impact damage.

Bolt M16X65

High-strength alloy steel (10.9 grade); heat-treated for tensile strength; surface zinc-plated for corrosion resistance; size M16×65mm; used to connect structural components (cross beam, angle steel) and hoisting parts (pad eyes) to the guiderail main body.

1. Thread wear from repeated installation and removal during maintenance; 2. Fatigue cracking from long-term vibration and load stress; 3. Corrosion from moisture and drilling fluid seepage into threads.

1. Tighten to OEM-specified torque during installation; retighten monthly; 2. Replace bolts if threads are stripped or cracks are found; 3. Apply anti-rust thread compound before installation to prevent corrosion and thread seizing.

4309300016

1 model hex nut

High-strength steel (8 grade); surface zinc-plated; matched with Bolt M16X65 to secure connections, preventing loosening from rig vibration. The hex design allows for easy tightening and removal with standard tools.

1. Thread wear from repeated tightening and loosening; 2. Deformation of the hex head from improper tool use (e.g., oversized wrench); 3. Corrosion leading to thread seizing.

1. Use the correct size wrench to avoid hex head deformation; 2. Replace nuts if threads are stripped or corrosion is severe; 3. Pair with spring washers to enhance anti-loosening performance; replace nuts when replacing bolts.

Spring washer 16

High-carbon steel (65Mn); heat-treated for elasticity; surface zinc-plated; size 16mm; installed between the bolt head/nut and component surface to absorb vibration, preventing nut loosening.

1. Loss of elasticity from long-term vibration and load stress; 2. Corrosion leading to breakage; 3. Deformation from over-tightening during installation.

1. Replace spring washers whenever bolts or nuts are removed; do not reuse worn washers; 2. Inspect monthly for corrosion and elasticity; replace if brittle or deformed; 3. Ensure proper alignment during installation to avoid uneven stress.

Spring washer 16

High-carbon steel (65Mn); heat-treated for elasticity; surface zinc-plated; size 16mm; identical to 4313000016, used as a redundant or auxiliary anti-loosening component for critical connections (e.g., pad eyes, cross beam).

Are these parts compatible only with Z05090900001AA BOP Handling Guiderails for ZJ40 Truck-mounted Drilling Rig? Can they be used for fixed ZJ40 rigs or other BOP guiderail models?

All parts are exclusively matched to the Z05090900001AA BOP Handling Guiderails, designed specifically for ZJ40 truck-mounted drilling rigs. They cannot be used for fixed ZJ40 rigs or other guiderail models, as mobile rig components are lighter, more vibration-resistant, and have unique connection dimensions. Using non-compatible parts causes structural instability, BOP handling risks, and safety non-compliance. For other rigs, provide the specific guiderail model for matching genuine parts.

2

Why are there two identical spring washer models (4313000016 and 4317100016), and can they be used interchangeably?

Both 4313000016 and 4317100016 are Spring Washer 16, identical in size, material, and function—they are interchangeable. They are provided as redundant or auxiliary components to ensure critical connections (e.g., pad eyes, cross beam) have enhanced anti-loosening performance, which is vital for mobile rigs facing frequent vibration. Using them in pairs for high-stress connections is recommended to prevent fastener loosening and ensure BOP handling safety.

What is the key maintenance focus to ensure BOP handling safety, and how often should critical parts be replaced?

Key maintenance focuses on safety: 1. Pre-hoisting inspections of pad eyes (check for wear/cracks) and fasteners (check tightness); 2. Monthly retightening of all fasteners and inspection of weld seams; 3. Quarterly corrosion checks and anti-corrosion touch-ups; 4. Replacement of spring washers every 6 months or when disassembled. Critical parts replacement timeline: Pad eyes (replace if wear/cracks are found, or every 24 months); bolts/nuts (replace every 18 months or if stripped); structural components (replace if deformed/cracked, per API Spec 8C inspections).
