What parameters are required for selecting a casing shoe?

The following information is required: Outer diameter and wall thickness of the casing pipe; Large and small step diameters at the interface between the casing drilling system and the casing shoe. For threaded casing shoes, the casing thread specification is also required.

Casing shoes are simple components. Why is there a significant price difference among products on the market?

The difference mainly depends on whether precision machining and proper heat treatment are applied. These casing shoes are manufactured from high-quality low-carbon alloy steel and processed with a mature heat treatment procedure, resulting in strength and hardness that significantly exceed typical market design requirements.
