BLADDER SYSTEM FOR CONDUIT EXPANSION

摘要

Disclosed is a bladder system (10) for use in conjunction with a conduit expansion process and system (12). In addition, the bladder system (10) is in operative communication with an injection material handling system (14). The bladder system (10) includes a bladder element (34) with injection hardware (40) positioned on one end and distal end hardware (42) positioned on the other end. The injection hardware (40) and the distal end hardware (42) are integrally attached to the bladder element (34), and the bladder element (34) is capable of expanding and contracting inside a liner conduit (16).
