YG225-17 Hook Support Pin, SL135-06 Packer & Full Series Compatible Components

Introduction & Core Purpose Statement

This complete line of oilfield replacement parts is precision-engineered for onshore/offshore drilling rigs, well completion tools, and RG Petro-machinery transmission systems, covering critical wear and structural components including the YG225-17 hook support pin, SL135-06 packer, mounting plate 116867, QF514C high-speed air release valve, and custom sealing & fastener kits. Target users include drilling rig maintenance crews, well completion service teams, oilfield equipment procurement managers, and field repair technicians who demand consistent performance, strict compliance with industry standards, and direct interchangeability with original equipment.

The core purpose of these parts is to eliminate two persistent oilfield pain points: unplanned downtime from premature part failure and mismatched components that break sealing integrity or structural stability. Every part is built to meet API Spec 5B, API Spec 6A, and GB/T3452.1-2005 standards, with exclusive factory-verified data: hook support pin tensile load capacity 89,000 lbs, packer sealing durability 1420 continuous operating hours, and O-ring static pressure resistance up to 105 MPa. Backed by decades of oilfield machinery manufacturing experience and strict batch testing, these parts provide a reliable, repeatable supply chain for daily upkeep, emergency repairs, and full rig overhauls.

Product Overview

This portfolio includes structural load components, fluid control valves, sealing elements, transmission parts, and specialized fasteners—all designed for direct drop-in replacement on standard drilling rigs and well completion tools. Each part is machined to tight dimensional tolerances (±0.02mm for critical interfaces) using oilfield-grade materials resistant to H2S, high pressure, and extreme vibration. No custom modification is needed; all parts match original mounting points, thread specifications, and performance ratings.

Core Function & Structural Advantages

Key Functions

The YG225-17 hook support pin carries full hook load during tripping operations, preventing lateral shift and safety risks. The SL135-06 packer creates a dependable downhole seal to isolate zone pressure and prevent fluid cross-contamination. The QF514C high-speed air release valve quickly vents trapped air to maintain stable pneumatic control. Transmission shafts, universal shafts, and sprockets deliver consistent power transfer without slippage. Custom O-rings, seals, and retaining rings block fluid leakage and dust intrusion, extending internal component life.

Structural Features

Load-bearing parts use forged alloy steel with quenched and tempered treatment for consistent strength. Sealing parts use nitrile rubber compounds tailored for oilfield drilling fluid compatibility, resisting hardening and cracking in low-temperature environments. Valve and packer components use precision-machined mating surfaces to eliminate bypass leakage. All fasteners and pins follow unified thread standards to avoid cross-threading during field installation.

Applicable Operating Conditions

These parts are rated for onshore and offshore drilling environments, operating temperatures from -35°C to 125°C, and working pressures up to 105 MPa. They are suitable for conventional drilling, well completion, and workover operations, and compatible with H2S-containing well fluids. All components meet explosion-proof and site safety requirements for Zone 1 hazardous locations, making them suitable for both land drilling pads and offshore platforms.

Field Maintenance & Care Recommendations

Inspect hook support pins and mounting plates for surface cracks or deformation before each rig shift; replace immediately if damage is found. Lubricate transmission shafts and universal joints every 7 days with extreme-pressure lithium grease to reduce wear. Replace O-rings and seals during every major maintenance interval—do not reuse deformed or compressed sealing parts. Store all parts in a dry, dust-free area; avoid stacking heavy loads on precision components like bearings and packers. Calibrate air valves and pneumatic seals every 90 days to maintain consistent response speed.
