Title:
SYSTEMS AND METHODS FOR STEAM SEPARATOR TIE BAR REPAIR OR REPLACEMENT
Document Type and Number:
WIPO Patent Application WO/2020/019003
Kind Code:
A3
Abstract:
Systems (100) enhance stand pipe (41) alignment and security with braces (101A, 101B) docking to the stand pipes (41). A link (150) connects pairs of braces (101A, 101B) so the braces (101A, 101B) and stand pipes (41) docked thereby cannot move relative to each other when fully secured. Partially securing braces (101 A, 101B) allows adjustment of the braces (101A, 101B) and distance between the same and thus stand pipe (41) position. Fully securing the braces (101A, 101B) makes the entire system (100) rigid without need for a tie bar (42). Braces (101 A, 101B) and links (150) can be installed and secured to the stand pipes (41) and among each other at an axial position from above the stand pipes (41), so that overhead, simple tooling may be used. A crimp nut (160) or other resilient connector may be used to secure the systems (101) from that single dimension with simple tooling. Any number of braces (101A, 101B), joining to any number of other braces(101 A, 101B), may be used in the system (100), and several systems (100) may be used at various levels.
