Application:

Use the flap valve automatic fill slurry collar, during the casing operation ,the slurry flow into sleeves automatically reduce the casing time minimize the impact on the floor. Before casting ball ,and good for circulation anytime will not advance the case of conversion.

Feature:

 1. Product specification is 4 1/2-5/8"
 2. In the small dimension sleeves to use this product will reduce the casing significantly when the impact of the formation
 3. Complete conversion with a drop ball after a product can continue to covert the lower part of other similar products
 4.Product button type currently only API oval buckle
 5.When the inclination is larger than 25° needing a falling ball release mechanism.
 6.Significantly reduce role in the formation of emotional stress can shorten the time of casing.
 7. Special cut structure of the flap valve keep open. This shear structure of both a good seal and easy to cut control
 8. PDC drill or roller bit can drill
 9.When using this float collar , the bottom of the guide shoe to the right series to ensure that flow is not cut and the short tube blocked up.
