Downhole Drilling Tools Replaceable Sleeve Stabilizer for 5 7/8''~28'' Hole Sizes
Replaceable sleeve stabilizer consists of mandrel and sleeve. The function is the same as spiral integral blade stabilizer. It can suit to different hole size and increase working life by changing the different size sleeve. The sleeve is threaded on the mandrel, so the sleeve can be fasten to the mandrel tightly and changed easily.
The Mandrel is made from AISI 4140/ 4145H modified alloy steel, fully heat treated to a Brinell Hardness range of 285 – 341. The connections are machined and finished according to API Specifications. Thread roots are cold rolled after machining, phosphatized to prevent galling during initial make-up, and installed with pressed steel thread protectors.
The Sleeve is an integral casting designed for easy make-up to the Mandrel. Hardfacing of the blades of the sleeves is done to increase the tool life. TIPTOP offers a range of Hardfacing materials to suit different drilling conditions.
