    Flush Mounted Slip FMS-375, 500 Ton 14 in

    The FMS-375 is mounted flush with the rig floor allowing the casing connection height to be lowered 1 meter (3 feet), eliminating the need for scaffolding. The rig crew also has more room to work by removing the spider body from the top of the rig floor. It is designed to fit into the opening of standard 37-1/2 in to 49-1/2 in rotary tables. The unit requires a 2000 PSI and 32 GPM hydraulic system for smooth, consistent and reliable operation. The spider utilizes the full range of slip assemblies and guides, 4-1/2 in to 14 in as used in the existing Varco Type V-500 ton elevator/spider. With top and bottom guides and the hydraulic power down feature for setting of the slip assemblies, the FMS-375 centers casing in the rotary, facilitating casing make-up with track mounted casing roughnecks and pipe stabbing equipment. When the slip assemblies are fitted with the National Oilwell Varco BJ circular insert buttons, the slip power down feature allows the spider to take the torque reaction of the tong when the string weight is not sufficient enough to resist rotating. The unit is provided with standard rotary locks for those times when the rotary torque needs to be transmitted to the casing string. In the event of loss of hydraulic power, the slip assemblies can be raised and lowered manually from one point at the top of the spider. The unit consists of two hinged body halves and top mounted lifting lugs, which allows the spider to be removed from the rotary table should this become necessary when the casing string is suspended from the elevator. The hydraulic connections and lubrication points are all located at the top of the spider, which allows quick hydraulic connection and easy maintenance while mounted in the rotary. A sturdy anti-skid top cover with casing door allows roughnecks to work safely around the well bore before and during the casing job. To prevent injury and to prevent items from falling into the well bore, the casing door remains closed when no casing is in the spider and is removed while casing is being run through the spider.
