Weatherford 16-25 Tongs & ZJ30 SJ Petro Hyd System

Core Purpose & Equipment Adaptation

Our drilling spare parts are precision-engineered and supplied to perfectly适配 (match) critical drilling equipment across multiple systems, including JC70DB drawworks, Weatherford 16-25 hydraulic power tongs and casing tongs, ZJ30 SJ Petro carrier hydraulic systems, BOP hoisting DZ500, 2500 Supreme series pumps, and 350/500 ton hoisting equipment. We directly address the unique, on-site pain points of three core user segments—drilling engineering teams, maintenance technicians, and procurement professionals—each relying on our parts to keep operations running safely and efficiently. Drilling engineering teams face the costly pain of unplanned downtime from failed components, which can halt drilling operations for hours; maintenance technicians need easy-to-install, durable parts with clear guidance to resolve faults quickly without specialized tools; procurement professionals require industry-standard, OEM-compatible parts that align with equipment specifications and safety regulations, eliminating the risk of ill-fitting or subpar components that lead to repeated replacements. The core purpose of our products is to ensure the continuous, safe, and efficient operation of drilling rigs by providing direct-fit, high-quality replacements for mission-critical components—covering mechanical, hydraulic, sealing, electrical, and filtration systems—all designed to withstand the harsh conditions of onshore and offshore drilling, reduce operational costs, and minimize downtime.

Maintenance & Care Recommendations

Proper maintenance of drilling spare parts is critical to extending service life, reducing replacement costs, and preventing unplanned equipment failure. Below are practical, on-site actionable guidelines—designed for ease of implementation by on-site technicians, with clear steps to keep parts performing reliably:

• Regular Inspection (60-100 Working Hours): Conduct visual and functional checks of all wear-prone parts—inspect JC70DB drawworks gaskets (1200006226) and oil seals (1300007211) for cracking or leakage; check 648414308 mechanical seals for wear or damage; test proximity sensors (N10000, N02-1010-010) for accurate detection; inspect filter elements for clogging. For Weatherford 16-25 tongs, check 122125-001 seal kits for signs of wear or fluid leakage.

• Filtration System Maintenance: Replace JC702.01.05.00 filters (for JC70DB drawworks) and filter elements (XTRALIS VSP-005 VESDA, RSC117503) every 500 working hours; clean filter housings monthly to prevent contaminant buildup—clogged filters restrict fluid flow, causing hydraulic system pressure spikes and component damage. Use only compatible filter elements to ensure filtration efficiency.

• Lubrication & Sealing Care: Apply cup oil grease (1300003055 for JC70DB) to bearings (1300156149), key shafts (601212392), and sleeve shafts (641102182) every 100 working hours to reduce friction and wear; apply anti-seize compound to studs (648401115), nuts (648402014), and stretching screws (РР201032894 80900-21) to prevent corrosion and seizing, especially in offshore environments. Replace seals and gaskets immediately if leakage is detected.

• Electrical Component Care: Keep proximity sensors, twisted screened instrumentation cables (10490038-002), and service loops (AY11384-1-1) clean and free of dust/mud to ensure reliable operation; check electrical connections monthly for tightness and corrosion—loose connections cause electrical malfunctions. Store spare electrical parts in dry, sealed packaging to prevent moisture damage.

• Timely Replacement of Worn Parts: Replace plunger pumps (PP1069271) and relief valves (H06-1018-010) if pressure regulation is inconsistent; replace gears (DT14862) and bearings if noise or play is detected; replace seal kits (122125-001) for Weatherford 16-25 tongs when seals show signs of wear to prevent fluid leakage and tong failure. Follow OEM guidelines for replacement intervals for high-wear components.

• Proper Storage of Spare Parts: Store all spare parts in a dry, well-ventilated area (relative humidity <60%) away from direct sunlight and drilling fluid/mud. Keep mechanical parts and fasteners in anti-corrosion packaging; store seals and gaskets in a cool environment to avoid rubber aging; keep electrical components in sealed containers to prevent dust and moisture ingress.

On-Site Fault Maintenance Cases

Below are 3 real, short on-site drilling rig fault cases—reflecting common issues faced by drilling teams—demonstrating how our direct-fit spare parts resolve critical problems quickly, minimize downtime, and restore operational efficiency:

Case 1: JC70DB Drawworks Fluid Leak & Bearing Damage

A drilling site reported persistent hydraulic fluid leakage from their JC70DB drawworks, accompanied by noisy operation from the bearing assembly. Inspection revealed a cracked 1200006226 gasket and worn 1300156149 bearing—caused by delayed gasket replacement and insufficient lubrication with 1300003055 cup oil grease. Solution: Replaced the 1200006226 gasket and 1300156149 bearing with our OEM-compatible parts, applied the recommended cup oil grease to the new bearing, and inspected the hydraulic line for additional leaks. The drawworks resumed leak-free operation, bearing noise was eliminated, and downtime was limited to 1.5 hours—avoiding a costly rig shutdown.

Case 2: Weatherford 16-25 Casing Tong Seal Failure

A Weatherford 16-25 casing tong experienced severe hydraulic fluid leakage, rendering it unable to clamp casing pipes securely. The issue was traced to a worn 122125-001 seal kit, which had degraded due to exposure to drilling fluid and repeated use.Solution: Replaced the worn seal kit with our direct-fit 122125-001 seal kit, cleaned the tong’s hydraulic components, and tested the clamping function. The casing tong resumed full functionality within 45 minutes, restoring casing operations and preventing delays in the drilling schedule.

Case 3: 2500 Supreme Pump Mechanical Seal Leak & Efficiency Loss

A 2500 Supreme MS pump experienced significant fluid leakage from the shaft area and reduced pumping efficiency. Inspection found a failed 648414308 mechanical seal and a worn 641102182 sleeve shaft—caused by contaminant buildup and lack of regular maintenance. Solution: Replaced the 648414308 mechanical seal and 641102182 sleeve shaft with our OEM-compatible parts, cleaned the pump’s internal components, and installed a new filter to prevent future contamination. The pump resumed leak-free operation, and pumping efficiency was restored to 100%, minimizing fluid waste and operational costs.
