Product Overview

The FDQ Series: Intelligent Pipeline Plugging Equipment for Maximum Uptime

Engineered for critical pipeline infrastructure, the FDQ Pipeline Plugging Equipment Series is the definitive line stopping equipment for oil, gas, and utility contractors. This advanced machine enables safe, reliable, and rapid pipeline isolation without shutdown, protecting your revenue and operational continuity.

The FDQ Series is a hydraulic-driven pipeline isolation tool designed for pipeline operating companies and repair contractors, enabling safe, pressurized (hot tapping and plugging) interventions to eliminate costly downtime and mitigate environmental risks.

Core Advantages & Selling Points:

• Zero Downtime Operations: Execute repairs, modifications, or maintenance on live lines. Our pipeline plugging device prevents production loss, saving companies hundreds of thousands per hour in potential shutdown costs.

• Engineered for Absolute Safety: Built to withstand design pressures up to 16MPa. Features integrated safety systems including pressure monitoring, emergency relief valves, and spindle anti-rotation for secure operation in hazardous environments.

• Unmatched Versatility & Range: A single solution covers a vast spectrum. From NPS 4″ (DN100) to NPS 80″ (DN2000), the FDQ series accommodates both Disc-type Heads and Folding Heads for standard and large-diameter lines.

• Robust & Intelligent Design: Hydraulic drive ensures powerful, controlled actuation. Models feature stroke length display and are built for durability in temperatures from -20°C to 80°C, ready for any field challenge.

Detailed Product Description & Technical Specifications

How It Works: The FDQ Process

The FDQ pipeline plugging equipment works as part of a coordinated system:

1. Hot Tapping: A separate tapping machine creates an entry point on the pressurized pipe.

2. Coupler Installation: A FDLX Plugging Coupler is installed onto the tap, providing a sealed gate valve.

3. Plugging Head Insertion: The FDQ machine, mounted to the coupler, inserts the plugging head (disc or folding) through the valve and into the pipe.

4. Isolation & Locking: The head is expanded to form a seal, isolating the downstream section. The FDQ’s mechanism locks it securely in place.

5. Safe Work Zone Creation: The isolated pipeline section can now be safely depressurized for repair, replacement, or modification.

Note: Stroke and plugging specifications can be customized per user requirements.

Core Components

• Main Drive Unit: High-torque hydraulic cylinder providing the power for insertion and retraction. Built with corrosion-resistant materials for long service life.

• Control System: Manifold with precision valves for smooth operation, pressure gauges for real-time monitoring, and integrated safety relief.

• Attachment Frame: Robust interface for secure connection to the FDLX series plugging coupler.

• Plugging Heads (Sold Separately): High-integrity Disc-Type Plugging Head and Folding-Type Plugging Head designed to match the pipeline ID and create a bubble-tight seal.

Solving Core Pain Points & Application Scenarios

Your Challenges, Our Solution:

• “A pipeline leak means massive financial loss and environmental liability.” → The FDQ equipment allows for immediate isolation and repair without stopping the flow.

• “Traditional repairs require shutdowns, costing millions in lost production.” → Our pipeline isolation tool enables non-stop intervention, protecting your bottom line.

• “Safety is paramount; we cannot risk accidents during live line work.” → With 16MPa design pressure, multiple safety locks, and controlled hydraulic operation, the FDQ series is engineered for the highest safety standards.

• “We need one versatile system for our diverse pipeline network.” → From 4″ to 80″, the FDQ series offers a scalable solution for your entire asset base.

Application Scenarios:

• Emergency Leak Repair: Quickly isolate a damaged section on a high-pressure crude oil or natural gas transmission line for safe repair.

• Preventive Maintenance & Modifications: Install bypasses, replace valves, or add tie-ins on live city gas or district heating networks.

• Pipeline Section Replacement: Isolate an old or corroded segment in a chemical or LPG pipeline for replacement without emptying the entire line.

• Critical Infrastructure Work: Perform safe interventions on pipelines running through environmentally sensitive areas or dense urban centers.

Client Testimonials & Success Cases

Trusted by major pipeline operators and service companies worldwide.

• Client: A National Gas Transmission Company

• Challenge: A critical 24″ (DN600) natural gas transmission line developed a leak at a crossing under a protected wetland. Shutdown was unacceptable due to supply commitments.

• Solution: The contractor utilized an FDQ100 unit with a ZFDT-125-24 folding head. The line was successfully isolated under full pressure.

• Result: The section was repaired within 8 hours. Zero gas release to the environment, zero supply interruption, and estimated cost savings exceeding $1.5M versus a shutdown scenario.

Frequently Asked Questions (FAQ)

Q1: Can the FDQ equipment perform true hot tapping and plugging (live line intervention)?

A: Yes, absolutely. The FDQ series is specifically designed as hot tapping and plugging equipment. It is used in conjunction with a tapping machine and a plugging coupler to safely isolate a section of a pipeline that remains in service and under pressure.

Q2: What is the difference between the Disc-Type (FDT) and Folding-Type (ZFDT) plugging heads, and how do I choose?

A: Disc-Type Heads are rigid and are used for standard pipeline sizes (up to NPS 40/DN1000 in our range). Folding-Type Heads are used for larger diameters (NPS 20/DN500 and above) as they can be inserted through a smaller opening and then expanded inside the pipe. Our team will recommend the correct head based on your pipe diameter and application.

Q3: Do you provide operational training and field support?

A: Yes. Comprehensive training is a cornerstone of our service. We provide detailed classroom and hands-on field training for your operators and maintenance staff. Furthermore, our technical support team is available to assist remotely or, if needed, can be dispatched for critical on-site support.
