Service Tool – Pyramid Technical Services

Retrieval, Safety & Access Systems

Pyramid provides complete solutions for the safe installation and retrieval of intrusive corrosion monitoring instruments under actual line pressure, up to as high as 6000 psi. These systems include both mechanical and hydraulic retrieval technologies based on best global industrial practices.

Retrieval Tool

Service Valve

Hot Tap Tool

Retractable Tool

Mechanical Retrieval Tool (Conventional System)

A manually operated tool designed for the safe removal and installation of plug assemblies under pressure.

Key Features :

Handwheel-driven mechanical operation.
Compatible with 2-inch mechanical access fittings.
Works with ER/LPR probes, coupons, and holders.
Integrated bleed valve for controlled depressurization.
Lightweight and easy to operate.
Suitable for normal (Oil & Gas) operating pressures.

Applications :

Onshore & Offshore fields
Process units with moderate pressures
Pipelines with standard access fittings

Hydraulic Retrieval Tool (High Pressure System)

This system is designed for high-pressure environments and heavy-duty retrieval where high mechanical force is required which makes the operation little unsafe.

Key Features :

Operates safely up to 10,000 psi.
Compact, lightweight construction for field use.
Smooth internal design eliminates thread galling.
Minimal discharge and hence environmental friendly.
Handles long or heavy probes with ease.
Compatible with hydraulic access fittings.
Suitable for Onshor/Offshore, sour service, and high wear-tear lines.

Performance Range :

Temperature: up to ~200°C
Tool length suitable for probes 130–1000+ mm
Removal clearance requirements: 800–2400 mm depending on size
Tool weight: approx. 20–35 kg
Complete kit weight: approx. 60–95 kg

Operating Principle :

Access through a hydraulic access fitting
The service valve provides isolation of the process line
Hydraulic tool uses controlled pressure to retrieve/insert devices
No internal threaded connections and hence no seizing possibilities
Ensures enhanced operational safety in systems containing sand, solids, or corrosive media

Service Valves (Single & Double Isolation)

Used between the access fitting and retrieval tool to enable safe, pressure-balanced operations.

General Features :

Single Isolation or Double Block & Bleed (DBB).
Pressure ratings up to 3600 PSI/6000 PSI/10000 PSI.
Full-port opening for smooth probe passage.
Built-in bleed valve for pressure equalization.
Suitable elastomeric or metallic sealing depending on required services.

Benefits :

Full isolation ensures zero release operations
Safe depressurization through built-in bleed valves
Supports routine maintenance while the pipeline stays online

Hydraulic Pumps (Manual or Air-Driven)

Manual Hydraulic Pump :

Portable
Ideal for short probes and routine work
Field-ready for onshore or locations where compressed air is not available

Air-Driven Hydraulic Pump :

High force output for long or heavy assemblies
Faster operation
Preferred for offshore operations and high-pressure applications
