Cosasco® Corrosion Monitoring Access Systems

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). RCS can provide access fittings for corrosion coupon or internal electronic corrosion monitoring devices, chemical injection and sampling as well as retrievers, service valves and a full range of tools for servicing the fittings. Refined and perfected over years of practical service, Cosasco Access Systems are the safest and most reliable internal corrosion monitoring systems for use in hundreds of applications in oilfields, refineries, and other plants where access into a pipe or pressure vessel is required. Using the Cosasco access systems, you can access high-pressure systems — under full working pressure — without shutdown or product loss, for the insertion and retrieval of corrosion monitoring and control components quickly and safely. This corrosion monitoring system is the result of meticulous attention to engineering design, precise manufacturing, and skillful assembly. With these basic ingredients, Cosasco Systems comply with all necessary pressure codes, as well as NACE MR0175 and MR0103 standards for the prevention of sulfide stress cracking (SSC).

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.

High Resolution Corrosion/Erosion Monitoring System

COSASCO® High Pressure Access System - Permits insertion and removal of probes, coupons and injection fittings into piping while it is in service and pressurized up to 6000 psi.
Cosasco Intermediate Pressure Retractable System - Safe and controlled insertion and retraction of probes, sensors and injection devices at pressures up to 1,500 psi.
The Cosasco Access System enables safe access to high pressure systems without the need for shutdown. An Access Fitting Assembly is welded or flanged to the piping. A hollow or solid plug is then screwed into the internal threads of the access fitting, and then covered with a protective cover with bleed valve. For removal of probes/coupons a portable 2" Service Valve and an RSL or RBS/RBSA Retriever are moved from one monitoring location to another as needed for retrieval
