Structural Features

Material & Design Advantages

Our parts are built to withstand the harshest drilling and industrial environments, with structural features that prioritize durability, compatibility, and safety—designed for real-world use, not just specifications:

1. High-Performance Materials

We use industry-grade materials tailored to each component’s function: high-strength alloy steel for drilling coupling XT-57 and HAMMER UNION 1002B50XXH (tensile strength ≥850MPa); Viton® and nitrile rubber for O-rings (P100203, 160 X7) and oil seals (170X200X16) (resistant to oil, high temperature up to 180°C, and corrosion); high-carbon chromium steel for bearings (43010300222, 23047834) for fatigue resistance; and precision-machined steel for pipe connections (1204PJNPS01A) and bolts. All raw materials pass ISO 9001:2015 certification, with a material qualification rate of 100%.

2. Precision Engineering

All parts are manufactured using CNC machining technology, with a dimensional tolerance of ±0.0025mm—ensuring perfect compatibility with OEM equipment. For example, the drilling coupling XT-57 has precision-threaded connections (thread pitch error ≤0.008mm) for leak-proof assembly; the Bush bearing P100110 (SPM TWS-600S) has a polished inner surface (Ra ≤0.3μm) to reduce friction; and the Round dies GOST 9740-71 (M48, M30 X3.5) have precise thread profiles for consistent, high-quality threading.

3. Safety & Durability Design

Many parts feature reinforced designs for harsh conditions: the Motor YB3-160M-4W is explosion-proof (EXdIIBT4Gb) and waterproof (IP65), suitable for offshore and onshore drilling sites; the HAMMER UNION 5″ 7500CWP FIG.1002 has a heavy-duty steel body to withstand high pressure (7500 psi) and impact; the Vibrating screen box 503 (250/100 mesh HDF-5) has a reinforced frame to resist vibration and extend screen life by 50%.

Applicable Working Conditions

Our parts are rigorously tested to perform in the most demanding drilling and industrial environments, covering key scenarios that match our users’ real-world operations:

• Oilfield Drilling: Suitable for 3NB-500 petroleum machinery, SPM TWS-600S mud pumps, NOV TDS-10SH top drives, ZJ-20 drilling rigs, F-800 mud pumps, and QWS-2500SD pumps. Withstands high pressure (up to 15,000 psi), corrosive drilling fluids, extreme temperatures (-45°C to 180°C), and heavy vibration.

• Hydraulic & Pneumatic Systems: Parts like Anti-Track Valve 810699-00-0100, Solenoid valve 04/7M 24DC, and hydraulic station YZBF-120LD are designed for high-pressure hydraulic systems, withstanding frequent pressure cycling and oil exposure.

• Hazardous Zones: Explosion-proof components (Motor YB3-160M-4W, EX 13-3-C-16-335PN plug) meet EXdIIBT4Gb standards, suitable for drilling sites with flammable or corrosive materials.

Maintenance & Care Recommendations

Proper maintenance of our parts will maximize their service life, reduce replacement costs, and ensure equipment safety. Below are practical, easy-to-follow recommendations based on years of industry experience—no technical jargon, just simple steps:

• Drilling Components: Inspect the drilling coupling XT-57 every 800 operating hours for thread wear or damage. Clean threads with a wire brush and apply anti-seize lubricant before installation. Replace if threads are stripped or cracked.

• Bearings & Bushings: Lubricate bearings (43010300222, 23047834) and Bush bearing P100110 (SPM TWS-600S) with API-grade grease every 600 operating hours. Check for abnormal noise or vibration—this may indicate misalignment or wear. Replace bearings if they show signs of rust or pitting.

• Seals & Gaskets: Check O-rings (P100203, 160 X7), OIL SEAL 170X200X16, and gaskets (turbocharger 65.09901-0033) every 400 operating hours for cracks, hardening, or deformation. Clean sealing surfaces to avoid debris, and replace seals if leakage is detected. Apply a thin layer of compatible lubricant to seals during installation.

• Filters: Replace transmission filter 1328876, Fuel filter PARKER RACORT800-344-3286, and FILTER ELEMENT SECOND FOR GARA-ALTYN RIG when pressure differential exceeds 0.35MPa. Clean filter housings regularly to prevent impurity buildup. Use only genuine filters to avoid damaging engines or pumps.

• Electrical Components: Inspect Intermediate Relay AC SK4-220d, Motor YB3-160M-4W, and Circuit breaker PR121/P-LSI every 1,000 operating hours for loose connections or damage. Keep electrical components dry and clean to prevent corrosion. Replace fuses and relays with the same rating to avoid electrical overload.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases, based on actual user experiences—providing practical guidance for equipment maintenance and part replacement, helping you quickly diagnose issues and minimize downtime:

Case 1: SPM TWS-600S Mud Pump Noise & Wear

Equipment Model: SPM TWS-600S Mud Pump
Fault Phenomenon: The pump produced loud noise during operation, and maintenance checks revealed excessive wear on internal components, leading to reduced performance.
Root Cause: The original bush bearing was low-quality, with poor surface finish and insufficient lubrication, causing increased friction and wear after 2,200 operating hours.
Solution: Replaced with our Bush bearing P100110 HPS GmbH SPM TWS-600S pump, which features a polished surface and high-wear resistance. After installation, the pump noise was reduced by 60%, and internal wear decreased significantly. The bush bearing has since lasted 5,800 operating hours—2.6x longer than the original part, reducing maintenance costs by 40%.

Case 2: 3NB-500 Petroleum Machinery Pressure Fluctuations

Equipment Model: 3NB-500 SJ PETROLEUM MACHINERY CO
Fault Phenomenon: The machinery experienced frequent pressure fluctuations during fluid discharge, leading to unstable operation and increased pump strain.
Root Cause: The original SPRING DISCHARGE VALVE was faulty, with a worn spring and imprecise valve seat, failing to regulate pressure effectively.
Solution: Installed our SPRING DISCHARGE VALVE P9000018AA, engineered to match 3NB-500 specifications. The valve’s high-strength spring and precision seat restored pressure stability (error margin ≤1.5%), and the machinery operated smoothly. The valve has lasted 4,500 operating hours—3x longer than the original, eliminating pressure-related downtime.

Case 3: ZJ-20 Drilling Rig Air System Malfunction

Equipment Model: ZJ-20 Drilling Rig (Air System)
Fault Phenomenon: The air system failed to respond properly, leading to delayed braking and safety risks during drilling operations.
Root Cause: The original Anti-Track Valve was worn and clogged, preventing proper air flow and reducing valve responsiveness.
Solution: Replaced with ourAnti-Track Valve 810699-00-0100, designed specifically for ZJ-20 air systems. After installation, the air system responded instantly, braking time was reduced by 45%, and safety was restored. The valve has operated reliably for 3,200 hours, with no signs of wear or clogging.
