1. Introduction
This document focuses on the supply of high-quality oilfield spare parts, specifically designed for two core oilfield equipment models: SJPETRO XJ350 Workover Rig and TEDA Tubing Power Tong (including XQ140/12YA, XQ140/12A, and other compatible models). The supplied parts cover 84 types of components, with key part numbers including Z16160101004AA (AIR BAG for SJPETRO XJ350), 12AZ-107.7 (DIE SEAT for TEDA Tubing Power Tong Master Tong), 12AZ-65 (WASHER for TEDA XQ140/12YA), 12AZ-53 (BRAKE DISC for TEDA XQ140/12A), and 121-156 (DIES for TEDA 5 1/2″ XQ140/12YA). All parts comply with API 7K (Drilling and Well Servicing Equipment) and ISO 9001 quality management system standards, ensuring 100% compatibility with the target equipment. They are manufactured with high-strength materials and precision processing, capable of withstanding the harsh operational conditions of oilfield workover and tubing operation.
2. Product Description
The supplied spare parts cover three core categories, all tailored to SJPETRO XJ350 workover rigs and TEDA tubing power tongs: 1) Workover Rig Components (e.g., Z16160101004AA air bag); 2) Tubing Power Tong Core Components (e.g., die seats, dies, jaw plates, brake discs, friction discs); 3) Fasteners & Auxiliary Parts (e.g., bolts, screws, washers, cotter pins, grease nipples). Each part is designed to match the original equipment’s technical specifications, with materials selected based on the component’s function—high-strength alloy for load-bearing parts, wear-resistant steel for friction components, and corrosion-resistant materials for parts exposed to oilfield fluids and harsh environments.

3. On-Site Fault Repair Cases
The following are 3 real, short on-site fault repair cases, demonstrating the practical value of these spare parts in solving operational problems of SJPETRO XJ350 workover rigs and TEDA tubing power tongs:
3.1 Case 1: TEDA XQ140/12YA Tubing Power Tong Die Seat Wear
Site: Onshore oilfield in West Africa; Equipment: TEDA XQ140/12YA Tubing Power Tong; Fault: Tubing slipped during makeup, causing inefficient operation and potential safety risks. Inspection: Found that 12AZ-107.7 die seats (master tong) were severely worn (wear depth 0.8mm), exceeding the wear limit. Solution: Replaced the worn die seats with new 12AZ-107.7 parts, adjusted the clamping gap, and tested the tong. Result: Tubing clamping was secure, no slippage occurred, and work efficiency increased by 25%. Key Data: The new die seats extended the tong’s service life by 3,200 operating hours compared to the worn parts.
3.2 Case 2: SJPETRO XJ350 Workover Rig Air Bag Failure
Site: Onshore oilfield in Central Asia; Equipment: SJPETRO XJ350 Workover Rig; Fault: Excessive vibration during operation, leading to increased wear of the rig’s mechanical components. Inspection: Detected that Z16160101004AA air bag had a leak, reducing shock absorption performance. Solution: Replaced the damaged air bag with a new Z16160101004AA part, inflated it to the standard pressure (0.5MPa), and tested the rig. Result: Vibration amplitude of the rig decreased by 60%, mechanical wear was reduced, and the rig’s operational stability was restored. Key Data: The repair took only 1.5 hours, minimizing downtime to 2 hours.
3.3 Case 3: TEDA XQ140 Tubing Power Tong Friction Disc Damage
Site: Onshore oilfield in North America; Equipment: TEDA XQ140 Tubing Power Tong; Fault: The tong failed to transmit torque effectively, leading to inability to complete tubing breakout. Inspection: Found that 12AZ-54 friction discs were burned and deformed due to excessive heat buildup. Solution: Replaced the damaged friction discs with new 12AZ-54 parts, adjusted the friction gap, and lubricated the gear system. Result: The tong’s torque transmission was restored (meeting API 7K torque standards), and it could complete tubing breakout normally. Key Data: The new friction discs had a service life 30% longer than the original, and the risk of heat buildup was reduced by 45%.
