4.10.09.013 spring washer & 1.07.14.001 Brake Pad

Introduction

In oilfield drilling operations, small components like fasteners and wear parts are the unsung heroes that keep equipment running—yet a single faulty part can trigger costly downtime. A loose 4.10.09.013 spring washer can cause bolt detachment, a worn 1.07.14.001 Brake Pad can lead to brake failure, and a damaged 1.10.05.003 IBOP Roller can disrupt well control—all resulting in non-productive time (NPT) that costs thousands of dollars per hour, safety hazards, and lost revenue. The spare parts listed, including 4.10.09.013 spring washer, 4.10.01.040 Hexagon socket head screw, 1.07.14.001 Brake Pad, 1.10.05.003 IBOP Roller, and 2.4.03.037 Filter element, are specifically engineered to fit TPEC Top Drive models (TDC-350, TDC-400, TDC-500, DQ40AⅢ-A), Tianyi Top Drive models (DQ50/3150DB, DQ70/4500DB, HDQ70/4500DB), and ZJ series drilling rigs (ZJ30, ZJ40, ZJ50), complying with the latest top drive model specifications. These parts cater to the unique needs of oilfield operation companies, drilling contractors, and on-site maintenance teams: whether you need an urgent replacement spring washer to secure bolts, a durable brake pad to restore safe braking, or routine fasteners like hex bolts and circlips 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—bolt loosening, premature wear, poor fit, and corrosion damage, especially critical for teams operating in remote or harsh oilfield locations where even a small part failure can halt operations entirely.

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 well control systems. The 4.10.09.013 spring washer and other fasteners (hex bolts, socket screws, circlips) secure critical components, preventing loosening caused by high vibration—solving the problem of bolt detachment that halts drilling operations, a risk highlighted by real-world incidents where even a single loose screw can compromise equipment safety. The 1.07.14.001 Brake Pad provides reliable stopping power for drilling equipment, avoiding brake fade and failure that endangers workers and equipment. The 1.10.05.003 IBOP Roller and 1.08.03.013 Upper Inner BOP ensure effective well control, preventing wellbore pressure issues that can lead to costly accidents. The 2.4.03.037 Filter element removes contaminants from hydraulic fluids, preventing system clogging and component wear. 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.

Function Description

Each spare part serves a unique and vital role in the drilling equipment system. The 4.10.09.013 spring washer creates tension between bolts and components, maintaining a secure fit even under high vibration—solving the problem of bolt loosening that causes component misalignment and failure. The 4.10.01.040 Hexagon socket head screw features a precision thread design that ensures tight engagement, with a torque capacity of 180 N·m, avoiding stripping and ensuring long-term reliability. The 1.07.14.001 Brake Pad delivers consistent braking torque of 860 N·m, preventing brake fade even in high-load, high-temperature conditions. The 1.10.05.003 IBOP Roller enables smooth operation of the inner blowout preventer, ensuring quick and reliable well control. The 2.4.03.037 Filter element traps particles as small as 2 microns, achieving a β 0.2 µm > 1000 efficiency rating to keep hydraulic fluids clean, avoiding system clogging and overheating. 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 4.10.09.013 spring washer is made of high-carbon steel with a zinc-plated coating, resisting corrosion and maintaining tension for 8,100 working hours—2,900 hours longer than ordinary spring washers. Fasteners like 4.10.01.040 Hexagon socket head screw and 4.10.02.062 Hex bolts meet ASTM A 453 Grade 660D requirements, produced via AOD refining for high corrosion resistance, with a tensile strength of 950 MPa and a fatigue life of 10⁷ cycles. The 1.07.14.001 Brake Pad uses a high-friction, heat-resistant material that withstands temperatures up to 350℃, preventing warping and brake fade. The 1.10.05.003 IBOP Roller is made of hardened alloy steel with a precision-machined surface, ensuring smooth operation and resistance to wear. The 2.4.03.037 Filter element features a stainless steel frame and high-efficiency filter media, with a collapse pressure exceeding 500 kPa to avoid filter failure under high pressure.

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), Tianyi Top Drive models (DQ50/3150DB, DQ70/4500DB, HDQ70/4500DB), and ZJ series drilling rigs (ZJ30, ZJ40, ZJ50), ensuring quick replacement and minimal downtime, even in remote locations where every minute of NPT is costly.

Maintenance and Care Recommendations

To extend the service life of our spare parts and ensure equipment safety, our engineers offer practical, on-site advice—drawn from real-world oilfield experience. For 4.10.09.013 spring washer, inspect them every 150 working hours for wear or deformation—replace if the washer loses its tension, as loose washers can lead to bolt detachment, a risk that oilfield professionals work tirelessly to avoid. A key engineer tip: never reuse 4.10.10.105 Circlip for shaft or 4.10.10.106 Circlip for shaft, as they lose elasticity after one use and can cause component dislodgment; always use the correct torque when installing hex bolts (120-180 N·m for 4.10.02.062 Hex bolts) to avoid stripping or under-tightening. For 1.07.14.001 Brake Pad, inspect the friction surface every 300 working hours and replace if the thickness drops below 8 mm. The 2.4.03.037 Filter element should be replaced every 450 working hours or when the differential pressure exceeds 150 kPa. The 1.10.05.003 IBOP Roller should be lubricated every 200 working hours to ensure smooth operation. Our team also provides on-site training to help your team master these skills and avoid common mistakes that lead to unplanned downtime.
