1.10.13.06 Anti-loosening flange & 2.4.04.002 Hydro pneumatic accumulator

Introduction

Oilfield drilling operations depend on the reliability of every component, from anti-loosening flanges that prevent connection failures to hydro pneumatic accumulators that stabilize hydraulic systems. A loose flange can cause dangerous leaks, a faulty accumulator can lead to hydraulic pressure fluctuations, and a worn IBOP roller can disrupt drilling operations—all of which result in costly downtime, safety risks, and lost revenue. The spare parts listed—including the 1.10.13.06 Anti-loosening flange, 2.4.04.002 Hydro pneumatic accumulator, 1.09.04.012R Lined elevator, and 2.3.03.012 Hydraulic cylinder—are specifically engineered to fit Tianyi Top Drive models (DQ15Z, DQ40, DQ50, DQ70), TPEC Top Drive models (TDC-350, TDC-400), and ZJ series drilling rigs (ZJ15, ZJ30, ZJ40, ZJ50). These parts are tailored to meet the unique needs of oilfield operation companies, drilling contractors, and on-site maintenance teams: whether you need an urgent replacement of a damaged Anti-loosening flange to stop leaks, a reliable Hydro pneumatic accumulator to stabilize hydraulic pressure, or routine maintenance parts to prevent unplanned breakdowns. Our core goal is to deliver fully compatible, durable, and cost-effective spare parts that solve the industry’s most frustrating pain points—frequent component failure, poor compatibility, difficult maintenance, and excessive replacement costs that eat into your profits, especially critical for small to medium drilling teams relying on efficient operations to stay competitive.

Backed by a team of 18 API-certified technicians and 11 TUV-certified safety engineers, we provide on-site technical guidance and maintenance support, ensuring each part is installed correctly and performs optimally—helping you avoid costly non-productive time (NPT), which can cost thousands of dollars per hour for drilling teams.

Product Overview

Core Purpose

These spare parts are essential for the normal operation, maintenance, and safety of oilfield drilling equipment, particularly top drives and ZJ series drilling rig hydraulic/mechanical/electrical systems. The 1.10.13.06 Anti-loosening flange ensures secure connections between pipelines and components, preventing loosening from vibration that causes leaks and equipment damage—solving the problem of connection failures that halt drilling operations. The 2.4.04.002 Hydro pneumatic accumulator stabilizes hydraulic system pressure, absorbing pressure fluctuations and preventing damage to pumps and valves, similar to how optimized accumulators in HHV systems provide reliable long-term performance. The 1.09.04.012R Lined elevator securely grips drill strings, ensuring safe and efficient lifting operations. The 2.3.03.012 Hydraulic cylinder provides the necessary force for drilling components, ensuring precise movement and avoiding inefficiency. Every part is designed to address specific operational pain points, keeping your drilling equipment running safely and continuously in harsh oilfield environments, while complying with industry safety and quality standards, and helping reduce maintenance costs and downtime like the innovative technologies used in江汉石油工程钻井 operations.

Function Description

Each spare part serves a unique and vital role in the drilling equipment system. The 1.10.13.06 Anti-loosening flange features a locking mechanism that resists vibration, ensuring connections stay secure even under high vibration (up to 58 Hz)—solving the problem of loose connections that cause leaks and downtime. The 2.4.04.002 Hydro pneumatic accumulator has a maximum working pressure of 31.5 MPa, storing hydraulic energy to stabilize pressure fluctuations within ±0.5 MPa, avoiding the common issue of pressure drops that reduce drilling efficiency. The 1.09.04.012R Lined elevator has a maximum load capacity of 500 tons, gripping drill strings securely without damage, ensuring safe lifting operations. The 2.4.20.442 High pressure water hose handles up to 42 MPa of pressure, delivering clean water for drilling operations and preventing leaks that can cause environmental hazards and equipment damage. All parts work together seamlessly to maintain the integrity, safety, and efficiency of the entire drilling system, supporting the high-performance needs of modern drilling equipment like the DQ15Z small-size top drive.

Structural Features

Our spare parts are designed with the harsh oilfield environment in mind, boasting structural advantages that outperform standard components. The 1.10.13.06 Anti-loosening flange is made of high-strength carbon steel with a corrosion-resistant coating, tensile strength of 900 MPa, ensuring it can withstand high pressure and vibration—extending service life to 7,600 working hours, 2,600 hours longer than ordinary flanges. The 2.4.04.002 Hydro pneumatic accumulator features a seamless steel shell, complying with API 6A temperature grades from K to V, and uses nitrogen for pressure stabilization (non-corrosive, ensuring no impact on service life), similar to the optimized accumulators used in HHV systems. Fasteners like 4.10.02.127 Hexagon bolt and 4.10.11.018 Nuts meet ASTM A 453/A 453 M grade 660D requirements, with a minimum 0.2% offset yield strength of 725 MPa for diameters up to 63.5 mm, and undergo hot-dip galvanization for corrosion resistance. The 2.4.51.028 O-seal is made of high-temperature resistant rubber, withstanding temperatures up to 120℃ to prevent seal failure. The 2.4.25.017 Steel pipe is precision-welded, with a maximum working pressure of 42 MPa, avoiding bursts in high-pressure systems.

Applicable Working Conditions

These spare parts are widely suitable for various oilfield scenarios, including onshore oilfields (Daqing Oilfield, Jianghan Oilfield, Permian Basin), offshore oil platforms (North Sea, Gulf of Mexico), and desert oilfields (Gobi Oilfield, Kazakhstan). They can withstand extreme temperatures ranging from -45℃ to 95℃, adapt to high humidity (up to 98%), high vibration (frequency 12-58 Hz), and high-pressure environments (up to 70 MPa). Whether for deep well drilling (depth up to 7,200 meters), horizontal drilling, or workover operations—including small-size rigs using DQ15Z top drives for ZJ15-30 rigs—our parts maintain stable performance. They solve the problem of poor adaptability of ordinary spare parts to harsh conditions, and are fully compatible with Tianyi Top Drive models (DQ15Z, DQ40, DQ50, DQ70), TPEC Top Drive models (TDC-350, TDC-400), and ZJ series drilling rigs (ZJ15, ZJ30, ZJ40, ZJ50), eliminating the hassle of finding mismatched components and ensuring quick replacement. This compatibility is critical for reducing downtime, as waiting for mismatched parts can cost thousands of dollars per hour in non-productive time, a key concern for drilling teams looking to optimize efficiency like those using innovative technologies in江汉石油工程 operations.

Maintenance and Care Recommendations

To extend the service life of our spare parts and ensure equipment safety and stability, our engineers offer practical, on-site maintenance advice. For the 1.10.13.06 Anti-loosening flange, check the locking mechanism every 150 working hours and re-tighten if necessary—this prevents loosening and leaks, a step many teams overlook. A key engineer tip: never reuse worn 2.4.60.002 Union seal; even minor damage can cause leaks that lead to hydraulic system failure and environmental risks, and always verify seal compatibility with your equipment’s as-built documentation. For the 2.4.04.002 Hydro pneumatic accumulator, check the nitrogen pressure every 500 working hours (similar to maintaining air conditioning systems) and recharge if it drops below 10 MPa, as insufficient pressure reduces its ability to stabilize hydraulic systems. The 1.09.04.012R Lined elevator should be inspected every 300 working hours for wear on the lining, and replaced if wear exceeds 2 mm. Never mix different types of fasteners, as this can lead to uneven load distribution and component failure. Our team also provides on-site maintenance training to help your team master these skills and avoid common mistakes, reducing maintenance costs and unplanned downtime.
