Our core purpose is to solve the most critical pain points these users face: unplanned downtime caused by incompatible or low-quality spare parts, high maintenance costs from frequent replacements, safety risks in high-pressure/high-load environments, and difficulty sourcing specialized components for older or niche equipment models. All spare parts comply with API 8C (for drilling hoisting equipment), API 6A (for wellhead and BOP equipment), ATEX EX d IIB T6 explosion-proof standards, and NACE MR0175 for H₂S environments, ensuring they meet the strict safety and performance requirements of oilfield operations. Backed by rigorous manufacturing processes, including third-party non-destructive testing (NDT) and pressure cycling, each batch of spare parts undergoes 100% factory inspection, with exclusive performance data: Brake Rim Assembly Z03010300030AA offers 11,000 working hours of service life, carbon brushes for YZ08 DC motor (T900/30178908-20) last 2,200 working hours, and the complete shear ram for 13 5/8 5000psi BOP withstands 7,000 pressure cycles at 5000psi—4,000 cycles more than generic alternatives. We provide a one-stop spare parts solution, ensuring customers can access all required components to keep their JC28/11B draw works, Canrig 1275 top drives, and 13 5/8 5000psi BOPs running smoothly, minimize downtime, and reduce long-term maintenance costs.

Product Overview

Core Product Categories & Functional Descriptions

Our spare parts are categorized by the equipment they serve, each designed to address specific on-site pain points and ensure optimal performance, directly solving the mechanical, electrical, and hydraulic faults that commonly cause equipment malfunctions:

• JC28/11B Draw Works Components: Brake Rim Assemblies Z03010300030AA and Z03010300031AA (main drum), helical gears (120681 bull, 120685 cluster, 120683 pinion), cluster gear shaft 120693, and RLA stem 124673-500. These parts ensure smooth, safe operation of the draw works, solving the problem of brake failure (a major cause of downtime) and gear wear that disrupts hoisting operations. The brake rim assemblies provide reliable stopping power for heavy loads (up to 2800kN), while the helical gears reduce noise and vibration, extending draw works service life by 2,800 working hours.

• YZ08 DC Motor Parts: Carbon Brushes T900/30178908-20 (25C14076P01) and 41B535803P3. These components ensure consistent power transmission for DC motors, solving the problem of motor overheating or failure caused by worn carbon brushes. Each carbon brush lasts 2,200 working hours, preventing frequent motor shutdowns and reducing maintenance time.

• Canrig 1275 Top Drive Components: 750 TON Bail DT11753 and 650/750 TON Pin Bail 753-15-0 (4.75 DIA). These parts handle heavy lifting loads (up to 750 tons) for Canrig 1275 top drives, solving the problem of bail or pin failure that halts drilling operations. The DT11753 bail is forged from high-strength alloy steel, ensuring it can withstand repeated heavy loads without deformation.

• 13 5/8 5000psi BOP Parts: Complete shear ram (with upper/lower seals), Ram Blocks RJ11172.15.01 (upper) and RJ11172.15.03 (lower), and Ram Seals RJ11172.15.02 (upper) and RJ11172.15.04 (lower). These components ensure reliable well control, solving the problem of BOP leakage or shear failure in high-pressure environments (up to 5000psi). The shear ram can cut drill pipe up to 4.5 inches, providing critical safety protection for well operations.

• Lifting & Rigging Parts: AY10084-2 Whale Hook Assy, AY10080 Runner Frame (rope guide), slings (1000-175-142, 1022-050-31), pin 1005-350-813, and shackle M19-2005-010. These parts ensure safe lifting and rigging operations, solving the problem of load instability or rigging failure. The 1000-175-142 sling (1 3/4 inch) handles up to 650 tons, while the M19-2005-010 shackle is galvanized for corrosion resistance in harsh environments.

Structural Features

All our spare parts are precision-machined and engineered to match the original equipment specifications of JC28/11B draw works, Canrig 1275 top drives, and 13 5/8 5000psi BOPs, making installation and replacement quick and easy—saving 55 minutes of on-site maintenance time per component on average. Key structural advantages align with API 8C and API 6A standards: brake rim assemblies (Z03010300030AA, Z03010300031AA) feature heat-treated surfaces (hardness 58-62 HRC) for wear resistance; BOP ram blocks (RJ11172.15.01, RJ11172.15.03) are made of high-strength alloy steel with precision-ground sealing surfaces (surface roughness ≤ 0.25μm) to prevent leakage; carbon brushes have a copper-graphite composition for low friction and high conductivity; and Canrig 1275 bail components (DT11753, 753-15-0) are forged and heat-treated to withstand 750-ton loads without fatigue. All electrical components (112554-D2 valve solenoid, 85890-C24 Versa solenoid valve) meet ATEX explosion-proof standards, ensuring safe operation in flammable drilling environments. Dimensional accuracy is strictly controlled (tolerance ≤ ±0.01mm for critical components), eliminating the need for modifications during installation.

Applicable Working Conditions

Our spare parts are designed to adapt to the harsh, diverse working conditions of oilfield operations where JC28/11B draw works, Canrig 1275 top drives, and 13 5/8 5000psi BOPs are used—including onshore desert oilfields, offshore platforms, high-temperature high-pressure (HTHP) wells, and H₂S-rich environments. They comply with API 8C and API 6A environmental requirements and can operate stably in temperature ranges from -60℃ to 160℃, pressure up to 70MPa (for BOP parts), and humidity up to 99%. Whether facing extreme temperature differences (desert day/night cycles), high salt spray (offshore platforms), high pressure (HTHP wells), or H₂S contamination, our spare parts maintain reliable performance. BOP parts meet NACE MR0175 standards to resist H₂S corrosion, while brake rim assemblies and gears are coated with anti-oxidation layers to withstand high temperatures. Lifting parts like slings and shackles are galvanized or coated to resist corrosion, ensuring long service life in harsh outdoor conditions.

Maintenance & Operation Tips

Based on years of on-site maintenance experience with JC28/11B draw works, Canrig 1275 top drives, and 13 5/8 5000psi BOPs, our engineers provide practical, easy-to-follow tips to extend spare part service life and reduce failures—aligned with API 8C and API 6A best practices:

• Draw works components: Inspect brake rim assemblies (Z03010300030AA, Z03010300031AA) for wear every 300 working hours; replace if wear exceeds 3mm. Lubricate helical gears (120681, 120685) every 200 working hours with high-temperature grease—our engineers remind that using low-grade grease can reduce gear life by 3,500 hours. Check RLA stem 124673-500 for alignment every 400 working hours to prevent jamming.

• YZ08 DC motor carbon brushes: Inspect brushes (T900/30178908-20, 41B535803P3) every 500 working hours; replace if length is less than 10mm. Clean motor commutator with a soft brush before installing new brushes to avoid arcing—this common mistake can damage the motor and reduce brush life by 800 hours.

• Canrig 1275 components: Inspect DT11753 bail and 753-15-0 pin bail for cracks every 600 working hours using magnetic particle testing (per API 8C requirements). Apply anti-corrosion grease to the pin bail every 250 working hours to prevent rust in humid environments.

• BOP parts: Inspect ram blocks (RJ11172.15.01, RJ11172.15.03) and seals (RJ11172.15.02, RJ11172.15.04) every 350 working hours; replace seals if they show signs of aging or damage. Test BOP pressure every 6 months to ensure it can withstand 5000psi—never exceed rated pressure, as this can cause permanent damage to the shear ram.
