Discover the applications and distinctive characteristics of centralizer stop collars, also known as position rings, stop circulars, brake rings, and more. These collars come in three types: mobile screw-type, fixed screw-type, and buckle-type. Their primary purpose is to prevent the axial movement of centralizers or cement baskets on the casing during cementing operations.
