STOP COLLAR HINGED WITH BOLT

TYPE 405 - STOP COLLAR – HINGED WITH BOLT The hinged Type 405 Stop Collar is designed to latch-on to the casing without having to be slipped over the end of the casing allowing for quick and easy installation. The holding force of the Type 405 is higher than the allowable centralizer starting force as specified in AP1 Specification 10D. It uses a nut and bolt assembly which when tightened draws the stop collar into a friction grip around the circumference of the pipe. This design does not produce markings or indentations on the casing after installation.
