Structured Product Description & Technical Details

1. Product Introduction

This portfolio includes 40+ high-demand accessories covering drill stabilizers, threaded adapters, coring tools, high-pressure valves, rotary joints, bearings, aviation plugs, butterfly valves, slings, sealing hoses, and chemical additives. Each product is made of high-grade alloy steel (42CrMoMn, 35CrMo), wear-resistant materials, and corrosion-resistant polymers, manufactured in strict accordance with API Spec 7-1, API 6A, and national mechanical standards. Key products feature precise dimensional processing (inner flat adapters 108mm-168mm, stabilizer lengths 1500mm-1700mm) and brand-certified quality (HRB bearings, SKF deep groove ball bearings, Maxxis tires, Philips lighting), ensuring 100% fit with supporting drilling and mechanical equipment without modification.

2. Function Description

• Drilling Tool Accessories: WL series drill stabilizers control well deviation and keep drilling trajectory straight; threaded adapters realize reliable connection between drill pipes of different diameters; CQX180-105 coring tools complete underground core sampling efficiently; lifting short sections assist safe hoisting of drilling tools.

• Well Control & Pipeline Parts: PFFY103-35 high-pressure valves regulate 35MPa wellbore fluid; 6BX high-pressure flange assemblies seal high-pressure pipelines; D7A1X5/D71F4 low-pressure butterfly valves control medium flow; high-pressure corrosion-resistant hoses transport high-pressure fluid without leakage.

• Transmission & Bearing Parts: Full-series bearings (self-aligning, cylindrical, tapered roller) reduce rotational friction and support heavy radial/axial loads; ZJXC rotary joints realize flexible rotation of test mining equipment with self-excited oscillation function.

• On-Site Auxiliary Accessories: Aviation plugs provide safe explosion-proof power connection; combination wrenches meet on-site maintenance disassembly needs; polyester slings and galvanized iron wire assist material lifting and binding; lighting and bulbs ensure night construction visibility.

• Oilfield Chemicals: SP-8 polymer fluid loss control agent stabilizes drilling fluid performance and reduces fluid loss in formation.

3. Structural Features

• High-Strength Material Forming: Drill stabilizers and coring tools adopt integral forging process, with uniform internal structure and no casting defects; high-pressure valves use 35CrMo alloy steel to resist pressure deformation.

• Precise Thread & Dimensional Design: Adapters and lifting short sections use right-handed regular/inner flat threads (TBG female buckle, NC56-W), with dimensional tolerance controlled within 0.02mm to avoid thread slipping and loose connection.

• Wear-Resistant & Corrosion-Resistant Surface Treatment: Bearing surfaces are quenched and tempered; galvanized iron wire and flange components undergo anti-corrosion treatment, adapting to humid and corrosive underground environments.

• Modular Quick Replacement: Rotary joints, square tiles, and valve accessories adopt modular structure, which can be disassembled and replaced with conventional tools, shortening on-site maintenance time.

4. Applicable Operating Conditions

All accessories are tested and verified for stable operation in the following harsh working conditions, fully meeting the needs of oilfield drilling and industrial construction:

• Pressure range: Low pressure 1.6MPa (butterfly valve) to high pressure 70MPa (high-pressure flange), 35MPa (oil well valve)

• Temperature adaptation: -30°C to 120°C, suitable for alpine, high-temperature desert and offshore drilling platforms

• Load bearing: Stabilizers and bearings support 5-50 tons of drilling tool load; slings bear 3 tons of lifting weight

• Environment: Corrosive drilling fluid, humid air, sandy desert, offshore salt spray environment

• Standards compliance: API 6A, API 7-1, GB mechanical bearing standards, explosion-proof electrical connector standards

5. Maintenance & Care Suggestions (Engineer On-Site Experience)

• Drill Stabilizer & Adapter Maintenance: Clean thread surface debris after each use, apply anti-rust grease; check for wear and cracks on the stabilizer body every 10 drilling cycles, replace worn parts in time.

• Bearing & Rotary Joint Care: Fill high-temperature lithium-based grease regularly (every 200 operating hours); avoid impact and overload operation to prevent bearing cage damage; check rotary joint sealing rings for aging monthly.

• Valve & Pipeline Accessory Upkeep: Flush butterfly valve and high-pressure valve cavity with clean fluid every 3 months; check hose surface for cracks and bulges, replace damaged hoses immediately; tighten flange bolts to specified torque to prevent leakage.

• Auxiliary Parts Maintenance: Store aviation plugs in dry and dust-free environment; avoid overloading polyester slings; replace energy-saving bulbs regularly to ensure lighting efficiency; keep galvanized iron wire dry to prevent rust breakage.
