工程常见问题
Blinds bolt to a companion flange for removable isolation. Caps are welded to pipe ends for permanent closure.
No. Blinds are solid except for optional jack screws or bleed holes specified on the drawing.
No. Match flange class and bolt/stud rating to the design pressure–temperature rating.
Figure-8 and paddle blinds are supplied from approved drawings with matching pressure class.
