Remote Intelligent Torque Testing System for Wellhead Valves

This system is specifically engineered for wellhead valves, including cock valves (IBOP) and manual/hydraulic gate valves, integrating high-precision torque detection with high-pressure testing. By utilizing an intelligent drive unit to simulate actual field operations, the system accurately measures opening and closing torque under varying pressure conditions. It supports full remote automation, effectively addressing the challenges of low efficiency, safety risks, and lack of data traceability associated with manual inspection of large-bore, high-pressure valves.

System Configuration

  • Intelligent Torque Drive Module: Features high-torque servo motors or hydraulic drives equipped with precision torque sensors, supporting multi-angle and continuous rotation testing.
  • High-Pressure Test Unit: Integrates automated pump sets and multi-channel pressure monitoring for synchronized body strength and sealing performance testing.
  • Universal Clamping Fixtures: An adjustable mounting platform with various quick-connect adapters fits multiple sizes of wellhead valves and cocks.
  • Remote Monitoring & Control Center: An industrial PLC-based console enables real-time synchronized display of video monitoring and torque/pressure curves.

Key Features

  • Integrated Torque-Pressure Analysis: Synchronized real-time plotting of “Torque-Time-Pressure” curves provides precise insights into internal valve friction and wear status.
  • High-Torque Output: Specifically designed for oilfield conditions, delivering stable torque output up to tens of thousands of Nm to handle valve operation under high differential pressure.
  • Remote Safety Barrier: Physical isolation of the test area allows operators to complete all procedures from a control room, featuring instant pressure relief protection for anomalies.
  • Digital Compliance Reporting: Automatically generates API-compliant electronic reports with encrypted data storage, supporting quick queries by serial number or test date.
