Description
Slip on set screw stop collar ring is a one-piece stop collar.
The outside ends of these heavy duty stop collar are generally tapered to a degree(single piece develled/double develled) which helps to hold the casing centralizer and avoid the ends to hit the Bows / Vanes when the casing centralizers are placed over them.
This kinds of set screw stop collar is recommended for small hole operation.
It is used when holding force requirement is very high.
The Slip on Set Screw Stop Collar are available in sizes 4-1/2" to 20" .
Hinged Stop Collars secure placement and limits travel on attachments to casing string.
The stop collar uses a single draw bolt tightening mechanism with "hardened inserts" to grip the casing once tightened.
Hinged Stop Collar is Designed to latch on the casing pipe without having to be slipped on at the end of the casing pipe allowing quick and easy installation.
On locking it can be tightened for a holding force upto 1000 % of the centralizer starting force as per API 10 D.
The locking mechanism is at 180 degrees of the hinge.
This design does not make any marks or indentations on the casing.
This style stop collar is available in 4-1/2in thru 20in.
