Oil Pipe Power Pliers Z6-73, Hydraulic Sucker Rod Power Tong XQ28/1.8Y and Related Oilfield Equipmen

Introduction: Solve Oilfield Operation Pains with High-Quality Parts

In oil drilling, workover and casing operations, the stability and durability of wellhead tools directly determine operational safety, efficiency and cost control. Every minute of equipment downtime due to damaged parts can lead to losses of thousands of dollars, not to mention potential safety hazards. We focus on supplying core parts for oilfield equipment, including oil pipe power pliers, hydraulic sucker rod power tongs, pneumatic slips, and their matching components—such as Z6-73 tooth block for oil pipe power pliers, XQ28/1.8Y hydraulic sucker rod power tong, TQ35 Roller 5 1/2″φ100 56.610.03, and 18 other key models listed. These parts are precisely designed to fit specific equipment models, solving the pain points of frequent part wear, poor compatibility, and difficult maintenance that plague oilfield teams, while ensuring long-term stable operation under harsh working conditions.

Our core purpose is to provide oilfield operators, maintenance teams and procurement personnel with cost-effective, reliable and compatible parts supply solutions. Whether you need to replace worn tooth blocks, faulty sliders, or match special-sized inserts for pneumatic slips, we can meet your customized needs. All parts comply with API Spec 7-1 standards—the authoritative benchmark for oil and gas drilling equipment—and have passed strict non-destructive testing (magnetic particle inspection and ultrasonic testing) to ensure each product meets the highest quality requirements. With 15 years of experience in oilfield parts production and supply, we have served more than 300 oilfields worldwide, with a cumulative supply of 120,000+ parts and a field failure rate of only 0.3%, which is far lower than the industry average of 1.2%.

Product Overview & Core Functions

Key Product Models & Compatibility

All parts we supply are designed for specific equipment models, ensuring perfect compatibility and avoiding the risk of equipment damage caused by mismatched parts. The main compatible models and core uses are as follows:

• Oil Pipe Power Pliers Z6-73 Tooth Block Z6-73: Specifically matched with Z6-73 oil pipe power pliers, used to clamp and rotate oil pipes during make-up and break-out operations, solving the problem of slipping and low torque during pipe handling.

• Hydraulic Sucker Rod Power Tong XQ28/1.8Y: Suitable for workover operations, used to quickly make up and break out sucker rods with a diameter range of 5/8″~11/8″, reducing manual labor intensity and improving operation efficiency.

• TQ35 Series Parts (Roller 5 1/2″φ100 56.610.03, Notched Gear 56.600.03, Double Gear 340 52.100-05): Matched with TQ35 casing power pliers, ensuring smooth operation of the tongs under high load, solving the problem of gear jamming and roller wear.

• Pneumatic Slips (kW-1200 120t, SDML 2-7/8″ 250t, W3 1/2-5″ Three-piece slips) and Inserts (001605126, 001605127, 1605128, 1605130): Used to fix drill pipes and casings during drilling, with strong clamping force and corrosion resistance, avoiding pipe slipping accidents.

• ZQ203 Series Parts (Jaw Plate Assembly 5-1/2″ 0101-15M00, Hydraulic Tongs Slider 17.01-12, Plug Screw 0101-26): Compatible with ZQ203-100 and ZQ203-125 hydraulic tongs, ensuring stable clamping and smooth sliding of the tongs.

Structural Features & Advantageous Design

Our parts adopt advanced structural design and high-quality materials to adapt to the harsh oilfield environment, with the following core features:

1. High-Wear Resistant Materials: Most parts (such as tooth blocks, jaw plates, and rollers) are made of high-alloy steel,经过 heat treatment to reach a hardness of HRC 58-62, which can withstand 8000+ make-up and break-out cycles without obvious wear, far exceeding the industry average of 5000 cycles.

2. Precision Machining: Using CNC machining technology, the dimensional tolerance is controlled within ±0.02mm, ensuring perfect fit with the original equipment, avoiding gaps and vibration during operation, and reducing noise and part damage.

3. Corrosion & High-Temperature Resistance: All parts are treated with anti-corrosion coating, which can resist the erosion of drilling fluid and high-temperature environment (up to 120℃) in the oilfield, ensuring stable operation in humid, high-salt and high-temperature working conditions.

4. Easy Maintenance: The structural design is simple and easy to disassemble, and the replacement process can be completed by 1-2 maintenance personnel within 30 minutes, reducing maintenance time and labor costs.

Applicable Working Conditions

Our parts are widely used in various oilfield operation scenarios, including:

• Onshore and offshore oil drilling operations, including vertical wells, horizontal wells and directional wells;

• Workover operations, such as sucker rod replacement, pipe string maintenance and well cleaning;

• Casing and tubing running operations, suitable for various specifications of casing (3-1/2″ to 5-1/2″) and tubing;

• High-pressure, high-temperature and high-corrosion oilfields, such as heavy oil fields and offshore oilfields.

Maintenance & Engineer’s Practical Advice

Proper maintenance can extend the service life of parts and reduce operational failures. Here are practical suggestions from our senior oilfield engineers with 20 years of on-site experience:

• Lubricate moving parts (such as rollers, sliders and gears) every 50-100 operating hours with high-temperature resistant lubricating grease, avoiding dry friction and wear;

• Check the wear status of tooth blocks and jaw plates every 30 days. If the wear depth exceeds 1.5mm, replace them in time to avoid slipping and pipe damage;

• Clean the surface of parts with diesel oil after each operation, and avoid using steam cleaning (which will cause grease loss and corrosion);

• Store spare parts in a dry, ventilated warehouse, away from moisture and corrosive substances, and regularly check the packaging to prevent damage;

• Avoid over-pressure and over-torque operation of equipment, which will cause premature damage to parts such as gears and shafts. The system pressure should not exceed 10MPa during operation.

Engineer’s Pitfall Reminder: Do not use non-original parts to replace, as their material and dimensional accuracy do not meet the standard, which may cause equipment jamming, pipe slipping and even safety accidents. We have encountered a case where a customer used a counterfeit ZQ203-100 jaw plate, which caused the pipe to slip during operation, resulting in a loss of $8,000.
