MPCH Master Bushing
MPCH Master Bushing – High-performance rotary table component designed for 17½" to 37½" drilling operations. Features pin/square drive compatibility, alloy steel construction, and API 7K certification for durability in extreme conditions. Enables secure kelly bushing engagement while supporting 250-ton loads. Includes interchangeable insert bowls (No.1/No.2/No.3) for flexible pipe handling. Reduces wear on rotary tables by 40% with heat-treated surfaces. Ideal for onshore/offshore rigs requiring reliable torque transfer and extended service life.
Product Details
Product Overview: API 7K-Compliant Turntable Cores & Insert Bowls
Material: High-grade alloy steel castings with H₂S/CO₂ corrosion resistance and boron-carbide surface hardening.
Design: Integral/split structures with distribution drive (for directional drilling) or square drive (standard rotary applications).
Compliance: Fully certified to API Spec 7K for drilling equipment safety, load capacity, and dimensional precision.

Core Advantages
- Extreme Environment Performance
- Temperature Range: -40°C to 200°C (-40°F to 392°F), validated for Arctic drilling and geothermal wells.
- Corrosion Resistance: Boron-carbide coating reduces wear by 60% in H₂S/CO₂-rich formations.
- Operational Efficiency
- Quick-Change Inserts: Swap insert bowls in <20 minutes using standard rig tools (e.g., Model #1024 to #1025).
- API Slip Compatibility: Works seamlessly with API RP 8B-certified slips (drill pipe, collar, casing) and roller cores.
- Load & Precision Engineering
- Static Load Capacity: 500+ short tons with zero slippage (grooves machined to ±0.002" tolerance).
- Split-Structure Benefits: Perform maintenance on MSS Split models without removing the turntable.
Technical Additions for Enhanced Credibility
- Material Testing: Alloy steel castings undergo UT/MT inspections and Charpy V-notch impact testing (-50°C).
- Dimensional Guarantee: Compliant with API Spec 7K Section 8.4 for rotary table interchangeability.
- Customization: Modify insert bowls (e.g., #1903 for 11¾"–13⅜" casings) for HPHT or sour gas well profiles.
