Product Description
API Set Screw Stop Rings
The stop ring design is a one-piece and secured in pace with set screws.
The stop rings have a superior holding force and are especially applicable in close tolerance situations. The stop rings/collars are manufactured from tubular steel. The flat surface allows the centralizers a smooth bearing surface for rotational application.
Features:
1. The stop collars are available in three types: Knock-On Type, Spiral Nail Type and Set Screw Type.
2. The stop collars can be installed on any position on casing to limit the axial movement of centralizers and cement baskets.
