40-415 CHA Hydraulic Set Anchor

Product Overview


The CHA is a high performance purpose built hydraulic set anchor designed for use anywhere an anchoring device is required in cased hole without creating an annular seal.  The extremely compact design provides ease of handling and rig floor make up while ensuring string flexibility and trouble free deployment into even the most difficult well profiles.  As standard the CHA is supplied with a threaded top coupling but is also available with an integral polished bore receptacle and latch profile for use with latch type seal assemblies. The CHA is set by applying pressure to the tubing string and a high performance internal locking mechanism ensures the anchor remains firmly set through repeated weight transfer cycles. As standard the CHA is manufactured from 4140 grade material with 10,000 psi yield (P-110). A wide variety of alternate materials and configurations are available for severe environments.
