While trying to simplify and improve the stimulation phase of the well, we have designed isolation sleeves that cannot only protects your 5k rated tubing head from pressure and erosion, but also provides significant cost savings. Designed to provide full-bore access to all 4 1/2” or 5 1/2” casing, the installation and retrieval can be done under full working pressure. FMC’s Isolation Sleeves can be used during preliminary work phase, fracturing and flowback operations. FMC combines the added safety, simplified installation, and durable design to provide financial savings over an Isolation Tool.
