Float equipment serves the backbone of casing equipment used during primary cementing operations, float equipment guides the casing to total depth and prevents contaminated mud from entering the casing. Also,it provides a landing point for casing wiper plugs, reinforces the lower end of the casing string, and ensures greater accuracy of cement slurry displacement. FEATURES: API 5CT,API 5B,API RP 10F rating,china petroleum department standarc SY/T5618-2000. Rounded nose profile helps guide the casing string(only for float shoe). The valve is made with phenolic material and molded with high strength concrete. Both the calve and concrete are easily drillable with PDC or rock bits. High strength design ensure excellent performance for flow endurance and back pressure holding. Automatically non-rotational groove design ensures corresponding cementing plugs drilled out quickly(only for non-rotating float collar). Single valve and double valve versions are available. Spring structure and bal structure valve are available: insret type and normal type are available.
