Cosasco® High Pressure Corrosion Monitoring System

Click to enlarge

This corrosion monitoring access system is the worldwide standard for high pressure access fitting systems and tools for “access under pressure” up to 6,000 psi (41 Mpa) and 450° F (232° C). The Cosasco High Pressure Access System includes access fittings for corrosion coupons or electronic corrosion monitoring, chemical injection and sampling as well as retrievers, service valves and a full range of tools for servicing the fittings. An access fitting with a solid or hollow plug in it carry the internal corrosion monitoring or injection device. The access fitting is permanently attached to the vessel or pipe, and the service valve and retriever are used to insert or remove the various probes, corrosion coupons or injection equipment.

Safety Bulletin: RSL Retriever

If you have purchased an RSL Retriever from RCS or other supplier, please click here to read important safety information in regards to the use of the Magnetic Swab Assembly. The RCS Magnetic Swab Assembly (RCS part number 121870) is a retrieval accessory used in conjunction with the RCS Hot Tap Tool, to remove hot tap cuttings from an access fitting before installing a device. If proper procedures are not followed during the swab operation, the Swab can potentially become detached from the retriever.
