Product Overview

Key Product Models & Functional Explanations

Every part we supply is designed to solve specific operational problems, with clear compatibility and performance advantages. Below are the core models and how they support your equipment:

• Lock nut 3P104372 (HPS GMBH): Specifically designed for SPM TWS-600S pump suction valve covers, this lock nut prevents valve cover loosening caused by high-pressure vibrations—solving the common issue of fluid leakage and pump inefficiency. It features a high-torque design (maximum torque 180 N·m) and corrosion-resistant coating, with a service life of 7,800 working hours—1,100 hours longer than standard lock nuts.

• NOV Seal 51300-385-F: Made of high-quality rubber, this seal is tailored for NOV TDS-10SH topdrives, preventing fluid leakage in rotating components and reducing unplanned shutdowns. It withstands temperatures from -45°C to 130°C and fits perfectly with original topdrive parts, with a sealing life of 5,500 working hours—800 hours longer than generic seals.

• Rubber Liner Assembly Z02040400004AA (SJ Petroleum): Designed for XJ350 workover rig balance shafts, this liner reduces friction and vibration, solving the problem of premature shaft wear. It is made of wear-resistant nitrile rubber, with a wear resistance of 6,200 working cycles and compatibility with all XJ350 rig models.

• Weatherford Die 487980 (541 0180): A 3/8” steel die for Weatherford TT 5.5-15 tongs, this part provides secure pipe gripping to prevent slipping during drilling operations. It is forged from high-strength alloy steel, with a hardness of HRC 58 and a service life of 4,800 clamping cycles—reducing replacement frequency by 2.5 times compared to standard dies.

• ZQ Hydraulic Tong ZQ 203-100 with Accessories: This complete hydraulic tong assembly includes all necessary accessories (jaw ZQ203-065, set screw ZQ203-057, brake band ZQ203-245) for quick installation, solving the problem of mismatched accessories and lengthy assembly times. It is compatible with 5 1/2” pipes and operates at a maximum torque of 150 kN·m, ideal for on-site pipe handling.

Structural Features

Our spare parts are built to withstand the harshest oilfield conditions, with structural designs that prioritize durability, compatibility, and ease of use:

• Precision Manufacturing: Using CNC machining technology, all parts have a dimensional accuracy of ±0.015mm, ensuring perfect fit with original equipment—eliminating installation delays caused by size deviations. For example, the 3P104372 lock nut has a thread tolerance of 6H, matching the SPM TWS-600S pump’s suction valve cover perfectly.

• High-Durability Materials: Critical parts (dies, lock nuts, shafts) are made of alloy steel with quenching and tempering treatment, achieving a tensile strength of 820MPa—resisting impact and corrosion in harsh oilfield environments. Seals and liners use nitrile rubber and Buna materials, with excellent oil and temperature resistance.

• User-Friendly Design: Parts like the Bushing Pull out Tool AH130101160100 feature an ergonomic handle for easy operation, reducing on-site labor time by 35 minutes per use. Modular components, such as the ZQ 203-100 hydraulic tong accessories, allow for quick replacement without specialized tools.

• Safety Compliance: All electrical and mechanical parts meet explosion-proof standards (Ex d IIB T3 Gb) and API 6A requirements, ensuring safe operation in hazardous oilfield areas. For example, the Cryogenic drive shaft 5000700994 is designed to withstand low temperatures down to -50°C, complying with cold-weather operation standards.

Applicable Working Conditions

Our spare parts are engineered to adapt to diverse oilfield environments, solving the problem of poor adaptability in extreme conditions:

• SPM TWS-600S Pumps: Parts like 3P104372 lock nut and Mechanical Seal WJQ56J0045 are designed for high-pressure pump operations (up to 42MPa), suitable for onshore and offshore well stimulation and cementing operations.

• NOV TDS-10SH Topdrives: Seal 51300-385-F and Packing 1540163 are ideal for continuous drilling operations with high loads (up to 500t) and high speeds (up to 120rpm), adapting to both desert and offshore environments.

• XJ350 Workover Rigs: Rubber Liner Assembly Z02040400004AA is compatible with both履带式 and轮胎式 XJ350 rigs, withstanding muddy, low-lying areas and high-vibration workover operations.

• Weatherford TT 5.5-15 Tongs: Die 487980 and related components are suitable for pipe handling in high-temperature (up to 150°C) and high-humidity environments, common in Middle Eastern and Southeast Asian oilfields.

• Cryogenic & Cold Environments: Cryogenic drive shaft 5000700994 and oil seal D170x200x16 (HG4-692-67) are designed for cold-weather operations (down to -50°C), ideal for oilfields in Siberia and northern Canada.

Maintenance & Care Recommendations

Based on 16 years of on-site engineering experience, we provide practical maintenance tips to extend part life and reduce costs—avoiding common mistakes that lead to premature failure:

• Seals & Liners: Check seals (51300-385-F, S01-1159-01N) every 300 working hours; clean the sealing surface with a non-abrasive cleaner before replacement, and apply a thin layer of 32# anti-wear hydraulic oil to prevent aging. Avoid using sharp tools during installation—this is a common mistake that causes 70% of seal failures.

• Lock Nuts & Fasteners: Tighten 3P104372 lock nuts to the recommended torque (180 N·m) using a torque wrench—over-tightening can crack the suction valve cover, while under-tightening causes leakage. Check fasteners (Hex Nut UNF-2B 55324-C, Quick bolt assembly 6417-6-1) every 500 working hours for looseness.

• Mechanical Parts (Dies, Liners): Grease the Z02040400004AA rubber liner every 200 working hours with lithium-based grease; replace the 487980 die when the wear depth exceeds 0.4mm to prevent pipe slipping. Store dies in a dry, oiled container to avoid rust.

• Hydraulic & Pneumatic Parts: Filter hydraulic oil for ZQ 203-100 hydraulic tongs every 1,000 working hours (filter precision ≤10μm) to prevent valve and cylinder wear. Clean the QF514 quick exhaust valve monthly to remove debris that causes air flow blockages.

• Storage Tips: Store all parts in a dry warehouse (temperature 5-25°C, humidity ≤60%); keep seals and gaskets (4P-3871, XJFH-5/35-1016) in sealed packaging to prevent aging. Avoid storing metal parts near corrosive substances—this extends their service life by 2,000+ working hours.
