Filter element 2.4.03.002 & Corrosion sleeve 1.01.39.001: High-Quality Oilfield Spare Parts

Introduction

In oilfield drilling operations, every component—from a filter element that keeps hydraulic systems clean to a corrosion sleeve that protects critical parts—plays a vital role in avoiding costly downtime. A clogged Filter element 2.4.03.002 can cause hydraulic system failure, a worn Corrosion sleeve 1.01.39.001 can lead to irreversible component damage, and a faulty 1.07.05.006 brake disc can compromise operational safety—all resulting in lost revenue, safety hazards, and prolonged non-productive time (NPT). The spare parts listed, including Filter element 2.4.03.002, Filter element 2.4.03.004, Corrosion sleeve 1.01.39.001, 1.19.02.5203 Fuel tank fixing plate TPEC top drive, and 1.07.05.006 brake disc, are specifically engineered to fit TPEC Top Drive models (TDC-350, TDC-400, TDC-500, DQ40AⅢ-A, DQ50Ⅲ-A), Tianyi Top Drive models (DQ50/3150DB, DQ70/4500DB), and ZJ series drilling rigs (ZJ30, ZJ40, ZJ50). These parts cater to the unique needs of oilfield operation companies, drilling contractors, and on-site maintenance teams: whether you need an urgent replacement filter element to unclog hydraulic systems, a durable corrosion sleeve to protect parts from harsh fluids, or routine maintenance components like retaining rings and O-rings to prevent unplanned breakdowns. Our core goal is to deliver fully compatible, long-lasting, and cost-effective spare parts that solve the industry’s most frustrating pain points—frequent clogging, corrosion damage, poor fit, and excessive maintenance costs, especially critical for teams operating in remote or harsh oilfield locations where reliable parts are hard to source.

All our spare parts comply with API Spec 7K (Drilling and Well Servicing Equipment), API Spec 6A (21st edition), ISO 9001:2015, and ISO 29001:2020 quality management standards. Our filter elements meet the latest API 614 requirements, with a clean pressure drop at 40°C of less than 30 kPa and a collapse pressure exceeding 500 kPa, while corrosion sleeves comply with NACE MR0175/ISO 15156 standards for sulfide stress cracking (SSC) resistance in H₂S-containing environments. Each unit undergoes strict functional testing, pressure resistance inspections, and corrosion resistance evaluations, with fasteners like 4.10.02.024 Head bolts with holes meeting ASTM A 453 Grade 660D requirements. We have 25 years of experience supplying oilfield spare parts, supporting over 326 oilfield projects across 40 countries—from China’s Daqing Oilfield and Shengli Oilfield to the U.S. Permian Basin, North Sea offshore platforms, and Gobi Oilfield in Kazakhstan. Our Filter element 2.4.03.002 maintains optimal filtration for 7,900 working hours, 2,800 hours longer than standard filters, and our Corrosion sleeve 1.01.39.001 resists corrosion for 8,300 working hours. Backed by a team of 21 API-certified technicians and 14 TUV-certified safety engineers, we provide on-site technical guidance and maintenance support, helping you avoid costly NPT that can reach thousands of dollars per hour.

Product Overview

Core Purpose

These spare parts are essential for the normal operation, maintenance, and safety of oilfield drilling equipment, particularly TPEC and Tianyi top drives and ZJ series drilling rig hydraulic, mechanical, and electrical systems. The Filter element 2.4.03.002, 2.4.03.004, and 2.4.03.027 remove contaminants from hydraulic and lubricating fluids, preventing system clogging and component wear—solving the problem of frequent filter replacement and system breakdowns. The Corrosion sleeve 1.01.39.001 and 1.06.06.001 protect critical components from corrosive drilling fluids and harsh environments, avoiding irreversible damage that requires expensive part replacement. The 1.19.02.5203 Fuel tank fixing plate TPEC top drive secures the fuel tank, preventing movement and leakage during high-vibration drilling. The 1.07.05.006 brake disc provides reliable stopping power, complying with API Spec 7K requirements to ensure operational safety. Every part is designed to address specific operational pain points, keeping your drilling equipment running safely and continuously in harsh oilfield environments.

Function Description

Each spare part serves a unique and vital role in the drilling equipment system. The Filter element 2.4.03.002 features high-efficiency filter media that traps particles as small as 2 microns, achieving a β 0.2 µm > 1000 efficiency rating to keep hydraulic fluids clean—solving the problem of clogging that causes system overheating and component failure. The Corrosion sleeve 1.01.39.001 is made of corrosion-resistant material with a protective coating, forming a barrier against corrosive fluids and extending component life. The 1.04.08.016 Bolt type cylinder controls mechanical movement with precise stroke control, avoiding jamming that halts drilling operations. The 2.4.05.003 Lubricating oil pump delivers consistent lubrication to moving parts, reducing friction and wear. The 1.07.05.006 brake disc provides stable braking torque of 860 N·m, preventing brake fade and ensuring safe equipment operation. All parts work together seamlessly to maintain system integrity, safety, and efficiency.

Structural Features

Our spare parts are designed with the harsh oilfield environment in mind, boasting structural advantages that outperform standard components. The Filter element 2.4.03.002 uses a non-welded design according to API 614, available in single configuration, with a stainless steel frame that resists corrosion and vibration—extending service life to 7,900 working hours. The Corrosion sleeve 1.01.39.001 is made of ASTM 316L stainless steel with a cross-linked polyolefin backing and heat-sensitive adhesive, ensuring strong bonding and long-term corrosion protection. Fasteners like 4.10.02.024 Head bolts with holes meet ASTM A 453 Grade 660D requirements, with a minimum 0.2% offset yield strength of 725 MPa. The 2.4.51.901 O-ring 120×6 is made of fluorocarbon, compatible with most chemicals and withstanding temperatures up to 130℃ to prevent seal failure. The 1.07.05.006 brake disc is fabricated from high-strength alloy steel, designed according to API Spec 7K, with low noise and reliable operation.

Applicable Working Conditions

These spare parts are widely suitable for various oilfield scenarios, including onshore oilfields (Daqing Oilfield, Shengli 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 100℃, adapt to high humidity (up to 98%), high vibration (frequency 12-60 Hz), and high-pressure environments (up to 75 MPa). Whether for deep well drilling (depth up to 7,800 meters), horizontal drilling, or workover operations, our parts maintain stable performance—solving the problem of poor adaptability of ordinary spare parts to harsh conditions. They are fully compatible with TPEC Top Drive models (TDC-350, TDC-400, TDC-500, DQ40AⅢ-A, DQ50Ⅲ-A), Tianyi Top Drive models (DQ50/3150DB, DQ70/4500DB), and ZJ series drilling rigs (ZJ30, ZJ40, ZJ50), ensuring quick replacement and minimal downtime.

Maintenance and Care Recommendations

To extend the service life of our spare parts and ensure equipment safety, our engineers offer practical, on-site advice. For Filter element 2.4.03.002, replace it every 450 working hours or when the differential pressure exceeds 150 kPa—delaying replacement can cause system clogging and overheating. A key engineer tip: never reuse 4.10.10.118 Retaining ring B or 4.10.10.119 Retaining ring A, as they lose tension after one use and can cause component detachment; always check seal compatibility with your equipment’s as-built documentation. For Corrosion sleeve 1.01.39.001, inspect the coating every 200 working hours for scratches—touch up with anti-corrosion paint if needed. The 1.07.05.006 brake disc should be inspected every 300 working hours for wear, replacing if the thickness drops below 8 mm. The 2.4.05.003 Lubricating oil pump should be checked for leaks every 250 working hours, and the oil should be replaced regularly to maintain lubrication efficiency. Our team also provides on-site training to help your team avoid common mistakes.
