Supporting and adjusting braces

Braces provide casing stability against wing and facilitate adjustments of casing elements.

Adjusting braces

Adjusting brace consists of:

Spindle block
Spindle, without supporting articulate plate
Intermediate post 3,70 m
Intermediate post 2,40 m
Spindle, with supporting articulate plate.

(Quantity and types of intermediate posts are shown in Table)

Main rule for choosing adjusting braces: Adjusting brace length should be 1,2 bigger then the distance from the place where casing elements installed to casing girth rail.
