Hinged Bolted Stop Collar
Can-Pro Downhole’s Hinged Bolted Stop Collars can be easily latched onto the casing pipe to keep Centralizers and attachments in place. This design features a draw-bolt to force the Stop Collar to grip the casing. The Collar consists of two pieces that are hinged at one end. On the other end, a single bolt is used to tighten the Collar to the casing. On locking it can be tightened for a holding force up to 10 times more than the Centralizers starting force as per API 10D. All Stop Collars undergo a special iron phosphate coating process to prevent corrosion and are then coated with a special polyester powder.
This product is available in all sizes ranging from 4 ½ “to 20”.
Any special sizes can be made upon request.
