Description

The hydraulic retrieval tool is precision equipment for online probe and coupon handling under full line pressure. EMT’s HRTV-000 model delivers 230mm retrieval stroke, 0-6000 PSI operating range, and a compact 30kg design — all PED compliant.

What Is a Hydraulic Retrieval Tool?

A retrieval tool is the tool that makes online corrosion monitoring practical. Without it, every probe swap or coupon inspection would require a shutdown and depressurization — expensive, disruptive, and often impossible in continuous operations.

EMT’s hydraulic retrieval tool (Model HRTV-000) uses a double-acting hydraulic cylinder driven by a manual hand pump. You connect the retriever to the service valve mounted on the access fitting, balance the pressures, open the valve, and pump to extend or retract the probe. The whole operation keeps your line at full working pressure.

This tool handles pressures up to 6000 PSI (414 bar) and temperatures from -60°C to +100°C. It works with any 2-inch access fitting and supports all EMT monitoring devices — corrosion coupons, ER probes, LPR probes, and injection assemblies.

Key Features

Hydraulic operation: The double-acting hydraulic cylinder cuts operator effort compared to mechanical retrievers — one person can handle the full retrieval/installation cycle

Wide pressure range: Operates from 0 to 6000 PSI (414 bar), covering everything from low-pressure water lines to high-pressure gas transmission

Compact and portable: Weighs just 30 kg with external dimensions of 176×176×1186 mm — fits into tight offshore and plant locations

Complete kit included: Comes with manual hydraulic pump, hoses, quick connectors, pressure gauges, service valve, copper hammer, wire brush, and hex wrenches — ready out of the case

Dual safety design: Available with single isolation service valve (one ball) or double isolation (two balls) for extra safety in high-consequence service

PED compliance: Fully compliant with the Pressure Equipment Directive — every unit tracked with serialized parts list and material certificates

Frequently Asked Questions

Q: Can I retrieve a corrosion probe while the pipeline is at full pressure?
A: Yes. The EMT hydraulic retrieval tool is designed exactly for this. Mount the retriever onto the service valve, balance pressures, open the valve, and use the hydraulic pump to extend or retract the probe. The entire operation happens under full line pressure — zero shutdown required.

Q: What is the difference between hydraulic and mechanical retrieval tools?
A: Hydraulic tools use a pump and cylinder to move the probe — easier on the operator, faster cycle time, and better control. Mechanical tools use hand-cranked screw mechanisms. Hydraulic is preferred for frequent operations, high-pressure lines, or when operator fatigue is a concern.

Q: How do I maintain the hydraulic retrieval tool?
A: After each use: disassemble, clean all internals with detergent, inspect seals and wear rings for scratches, lubricate threaded surfaces with anti-seize compound. Change hydraulic fluid if it may have been contaminated. Before storage: preserve with multi-purpose lubricant and keep in the original transport case in a dry indoor area.

Q: What pipe sizes does the retrieval tool support?
A: The standard HRTV-000 handles up to 12″ pipe with 600mm stroke. EMT also offers extended models for 24″ (881mm stroke) and 36″ (1184mm stroke) pipelines. The same pump and service valve work across all sizes.

Q: What safety training is needed to operate the retrieval tool?
A: EMT strongly recommends formal training. Only trained personnel should operate the hydraulic retriever. The operation involves high-pressure fluids, and incorrect procedures can cause injury. EMT provides training programs covering assembly, pressure balancing, retrieval/installation procedures, and emergency response.
