Typical Rupture Disc Application for Slurry Pipeline System

Product catalog summary

Introduction: The document discusses the application of rupture discs in copper mining, particularly in mines located at elevations of 1500 meters or higher. These mines transport copper concentrate, tailings, or minerals diluted in water through high-pressure pipelines, which are prone to corrosion due to calcium carbonate used in the process.

Problem: The pipelines, designed to operate at pressures up to 3700 psig, experienced heavy internal scaling and corrosion, leading to increased wall thickness and reduced internal area.

Solution: To address these issues, three valve stations were installed to section off the pipeline, limiting static head pressure. Rupture discs with set points up to 4000 psig were used to protect each pipeline section from overpressure. These discs were preferred over relief valves due to the severe service conditions of the copper concentrate slurry.

Implementation: Each valve station included three block valves (isolation, seal, and wear valves) and a rupture disc installed ahead of each isolating valve. The rupture discs were equipped with a BDI Alarm System to alert operators of a burst, which is crucial due to the remote location of valve stations.

Benefits: The use of rupture discs reduced downtime and maintenance costs, prevented galvanic action, and minimized environmental impact by ensuring plant water discharge was environmentally friendly. The system also provided operating cost savings and allowed for the reuse of outfall water.

Case Studies: Companies like Anglo American Chile Division Los Bronces and Cia. Minera Doña Ines de Collahuasi successfully implemented rupture discs in their copper concentrate mining operations.

Contact Information: The document provides contact details for Continental Disc Corporation's headquarters and international offices in China, Dubai, and the Netherlands.

Regulatory Compliance: The document mentions compliance with the Pressure Equipment Directive, China Manufacture License, and ASME Code Symbol Stamp, available when specified.

Typical Rupture Disc Application for Slurry Pipeline System-2

Typical Rupture Disc Application for Slurry Pipeline System IN the mining of copper, there is an interesting application for rupture discs. This application is typical for mines located at elevations of 1500 meters or higher, and transport concentrate, tailings, or mineral diluted in water through a high pressure pipeline, and where measures have been put in place to reduce and control the corrosion occurring due to heavy internal scaling of the customers’ high pressure pipeline. This corrosion occurs due to the calcium carbonate used in the process to keep the pH level during the transfer of...
