1. Product Introduction
This document focuses on the production and supply of high-quality OEM-compatible spare parts specifically designed for TEDA power tong systems, covering a full range of core models including hydraulic power tong TEDA XQ114-6B, tubing power tong TEDA XQ140, XQ140/12YA, XQ140/20, heavy-duty power tong TQ340, and ZQ127/25 models. The core purpose is to provide one-stop, drop-in replacement parts solutions for drilling operations, ensuring each part perfectly matches the original TEDA specifications—from critical structural components (Z6-136 Hanger Assembly) to precision wear parts (12AZ-54 Friction Disc)—to eliminate unplanned downtime and maintain safe, efficient tubular connection operations (making up and breaking out drill pipe, tubing, and casing).
2. Functional Instructions
- Z6-14 Duplex Gear Shaft (XQ114-6B) & 12AZ-49 Duplex Gear (XQ140): Transmit power from the hydraulic motor to the main shaft, converting rotational force into high torque (up to 16 kN·m for XQ140) for making up/breaking out connections.
- 12AZ-40 Main Shaft Gear (XQ140): Delivers torque to the jaw assembly, ensuring smooth, consistent rotation even under heavy loads. Precision gear teeth minimize wear and noise.
- TQ340-169 Idler Gear (TQ340): Maintains proper gear mesh alignment, distributing load across the transmission to extend the service life of primary gears.

3. On-Site Fault Repair Case Studies
Real-world, short case studies demonstrate how using high-quality, OEM-compatible TEDA power tong parts resolves common failures quickly, reduces downtime, and ensures operational safety.
Case 1: XQ140 Torque Inaccuracy Fixed with 12AZ-260 Torque Meter
Scenario: An onshore rig using a TEDA XQ140 tubing power tong experienced inconsistent torque readings, leading to 6 hours of NPT and rejected pipe connections. The existing torque meter displayed erratic values.
Solution: Technicians replaced the faulty unit with a new 12AZ-260 Torque Meter (60-16KN.m), pre-calibrated to API 7K standards.
Outcome: Repairs completed in 45 minutes. The new meter provided stable, accurate readings, eliminating connection rejections and avoiding an estimated $180,000 in additional NPT.
Case 2: XQ114-6B Gear Slippage Resolved with Z6-14 Duplex Gear Shaft
Scenario: An offshore platform’s TEDA XQ114-6B hydraulic tong slipped under load during casing makeup, posing a safety risk. Inspection revealed excessive tooth wear on the original duplex gear shaft.
Solution: Installed a replacement Z6-14 Duplex Gear Shaft, machined from heat-treated 42CrMo steel for enhanced wear resistance.
Outcome: Repairs completed in 2 hours during a scheduled window. The tong operated for 800+ hours without further issues, avoiding a $300,000 unscheduled shutdown.
Case 3: XQ140/12YA Braking Failure Addressed with 12AZ-54 Friction Discs
Scenario: A workover rig’s TEDA XQ140/12YA tong failed to hold position during tubing retrieval. The 12AZ-54 Friction Discs were glazed and worn smooth, rendering the brake system ineffective.
Solution: Replaced worn discs with new 12AZ-54 Friction Discs and cleaned the brake assembly.
Outcome: Braking functionality restored in 1 hour. The new discs showed no wear after 30 days of continuous use, preventing a potential safety incident.
4. Frequently Asked Questions (FAQ)
| No. | Questions | Answers |
| 1 | Are these parts compatible with all serial numbers of TEDA XQ114-6B, XQ140/12YA, and TQ340 power tongs? | Yes. All parts are engineered to match the original design specifications of TEDA XQ114-6B, XQ140/12YA, XQ140/20, ZQ127/25, and TQ340 models, regardless of production year. Critical dimensions, spline counts, and mounting patterns (e.g., Z6-136 Hanger Assembly, 12AZ-40 Main Shaft Gear) are identical to OEM parts, ensuring a perfect fit without modifications to your existing equipment. |
| 2 | What is the service life of 12AZ-54 Friction Discs and 12AZ-94 Pulling Springs under heavy onshore drilling conditions? | Under heavy onshore use (10+ hours daily), the 12AZ-54 Friction Disc has an average service life of 200-250 operating hours. The 12AZ-94 Pulling Spring (diameter 17, length 95) is designed for fatigue resistance, lasting 1,500-2,000 operating hours. Proper lubrication and regular inspection can extend these lifespans by up to 30%. |
| 3 | Do these parts meet API 7K and ISO standards, and do you provide documentation for compliance? | Yes. All load-bearing, torque-transmitting, and safety-critical parts (e.g., Z6-71 Jaw Set Bracket, 12AZ-260 Torque Meter, 12AZ-40 Main Shaft Gear) comply with API 7K and ISO 9001 standards. We provide mill test reports (MTRs) for metal components, calibration certificates for torque meters, and compliance statements for all parts—supporting your API 7K rig certification requirements. |
