Product Overview & Core Advantages

Key Spare Parts & Equipment Compatibility

All our spare parts are precision-manufactured to match specific equipment models, eliminating the risk of mismatches that cause equipment jams or damage. Below are the core models and their corresponding key spare parts, along with how they solve on-site pain points:

• Casing Power Tongs (TQ35-13, TQ340-35): Compatible spare parts include TQ35-13 3/8″ brake shoe (56.342.00), TQ35 brake spring (24.110.06), TQ340-35 bearing (22212C/W33 GB), and TQ340-35 anti-wear washer (56.320.04). These parts solve the problem of reduced braking efficiency and increased wear caused by high-load operations—our brake shoes have a wear resistance of 1,200 working hours, and bearings are pre-lubricated with high-temperature grease to withstand 120℃ on-site temperatures.

• Hydraulic & Liquid Gas Tongs (ZQ203-125, ZQ203-100): Spare parts such as ZQ203-125 liquid gas tongs oil inlet pipeline (φ19*2-25Mpa), ZQ203-100 lifting cylinder balance valve (DS-100), and ZQ203-125 jaw plate assembly (8″ 19.100-17-00) address issues like oil leakage, unstable lifting, and slipping during pipe making-up/breaking-out. The oil inlet pipeline is designed to withstand 25Mpa pressure without bursting, and jaw plates feature a thickened tooth design to grip pipes firmly without slipping.

• Oil Pipe & Drill Pipe Equipment: SDXL drill pipe slips (3 1/2″), XQ140/12YA brake disc (12AZ-53), and FFFX float valve joint spool (430*NC460) solve problems such as pipe slipping, uneven braking, and valve blockages. Our drill pipe slips can bear a maximum load of 80 tons, and brake discs have a heat dissipation coefficient of 45W/(m·K) to prevent overheating during long-term use.

Structural Features & Functional Advantages

Our spare parts are engineered with oilfield-specific working conditions in mind, with structural features that enhance durability and usability:

• Material Selection: All metal parts are made of high-strength alloy steel (such as P110 for anti-sulfur joint) with anti-corrosion and anti-wear treatment, suitable for harsh environments like high-sulfur oilfields and offshore drilling. O-rings (e.g., TQ16 O-ring 26501980) are made of nitrile rubber complying with GB3452.1-92, ensuring good sealing performance and resistance to oil and high pressure.

• Precision Manufacturing: Each part undergoes CNC machining with a dimensional tolerance of ±0.02mm, ensuring perfect fit with the original equipment. For example, the TQ35 sensor (TZS-K) has a signal transmission accuracy of ±0.5%, avoiding misalignment and false alarms during operation.

• Easy Installation: Spare parts are designed to be compatible with the original equipment’s installation structure, requiring no modifications—saving on-site installation time by 30 minutes per part on average. For example, the XYQ6B positioning pin (Z6-69) can be installed with standard tools, reducing the need for specialized equipment.

Applicable Working Conditions

Our spare parts are suitable for a variety of oilfield operation scenarios, including:

• Onshore and offshore oil drilling, well workover, and completion operations

• High-sulfur oilfields (anti-sulfur parts like 3-1/2″ EU male*IF mother joint comply with NACE MR0175 standard)

• Low-temperature environments (down to -40℃) and high-temperature areas (up to 150℃)

• High-load operations (such as casing running with 120-ton load and drill pipe making-up/breaking-out with 8700 N.m torque for ZQ203-125 tongs)

We supply the following spare parts:

On-Site Fault Repair Cases (With Real Data & Customer Feedback)

Below are 4 real on-site repair cases from different oilfields, showing how our spare parts solve practical problems and improve operational efficiency:

Case 1: Casing Power Tong Brake Failure in Daqing Oilfield

Location: Daqing Oilfield, Heilongjiang Province, China
Equipment Model: TQ35-13 casing power tong
Problem: Brake shoe wear led to reduced braking efficiency, with braking distance increasing from 0.8m to 2.1m, unable to meet the 1.2m safety standard. The original brake shoe (non-original) only lasted 450 working hours.
Replacement Part: TQ35-13 3/8″ brake shoe (56.342.00)
Data After Repair: Braking distance reduced to 0.7m, wear resistance increased to 1,200 working hours. The tong could stably brake under 100-ton load.

Case 2: Hydraulic Tong Oil Leakage in Shengli Oilfield

Location: Shengli Oilfield, Shandong Province, China
Equipment Model: ZQ203-125 liquid gas tongs
Problem: Oil inlet pipeline (φ19*2) burst due to insufficient pressure resistance, causing oil leakage of 15L/h and forcing operation shutdown.
Replacement Part: ZQ203-125 liquid gas tongs oil inlet pipeline φ19*2-25Mpa
Data After Repair: No oil leakage detected, pipeline withstood 25Mpa pressure (10% higher than on-site working pressure of 22.5Mpa), and operation resumed within 1 hour.
Customer Feedback: “The replacement pipeline is durable and perfectly matches our ZQ203-125 tongs. The quick installation saved us valuable operation time, and there has been no leakage for 6 months.”

Case 3: Drill Pipe Slip Slipping in Tarim Oilfield

Location: Tarim Oilfield, Xinjiang Uygur Autonomous Region, China
Equipment Model: SDXL drill pipe slips 3 1/2″
Problem: Slipping occurred during drill pipe clamping, with a maximum slip distance of 5mm under 70-ton load, risking pipe damage and safety accidents.
Replacement Part: SDXL drill pipe slips 3 1/2″
Data After Repair: Slip distance reduced to 0mm, clamping force increased to 80 tons, meeting the on-site load requirement of 75 tons. The slips maintained stable clamping for 800 working hours.

Case 4: Bearing Damage in Bohai Offshore Oilfield

Location: Bohai Offshore Oilfield, Tianjin, China
Equipment Model: TQ340-35 casing power tong
Problem: Bearing (22212C/W33) damage caused abnormal noise (85dB) and reduced rotation speed from 33r/min to 25r/min, affecting casing running efficiency.
Replacement Part: TQ340-35 casing power tong bearing 22212C/W33 GB
Data After Repair: Noise reduced to 55dB (below the 70dB on-site standard), rotation speed restored to 33r/min, and bearing temperature maintained at 65℃ during 1,000 hours of continuous operation.
Customer Feedback: “The bearing fits perfectly and runs smoothly. The offshore environment is harsh, but this part has withstood the test of high humidity and salt spray, greatly reducing our maintenance frequency.”

Maintenance & Engineer Tips

Maintenance Recommendations

Proper maintenance of spare parts can extend their service life and ensure equipment stability. Here are practical tips for on-site maintenance:

• Brake shoes, jaw plates, and tooth blocks: Inspect every 200 working hours for wear; replace when wear exceeds 3mm to avoid reduced performance.

• Bearings and pneumatic tire clutches: Add high-temperature lubricating grease every 300 working hours; clean the surface to prevent dust and oil accumulation.

• Seals and O-rings: Check for cracks or deformation every 150 working hours; replace immediately if any damage is found to prevent oil or gas leakage.

• Sensors and communication lines: Regularly check the connection for looseness; avoid pulling or bending the lines to prevent signal loss.

Engineer Pitfall Reminders

Based on years of on-site experience, we summarize the following common pitfalls to avoid:

• Do not use non-compatible spare parts to save costs—this can cause equipment jams, secondary damage, and even safety accidents. For example, using a non-GB standard bearing in TQ340-35 tongs can reduce the bearing’s service life by 60%.

• When installing jaw plates and brake shoes, ensure they are tightly fixed; loose parts can cause uneven wear and affect equipment performance.

• Avoid overloading the equipment beyond the spare parts’ capacity—for example, the SDXL 3 1/2″ drill pipe slips should not bear more than 80 tons to prevent damage.

• Store spare parts in a dry, dust-free environment; avoid exposure to moisture and high temperature, which can cause corrosion or deformation.
