Cost Effectiveness

Necessary time for blinding or deblinding

Size Ranged	Typical	Sammi Line Blind	Saving Effect
1/2”~ 14” (DN15~DN350)	2~4 man gasket, tools, lifter	by 1man	2~16 man-hours Gasket, bolts & nuts,tools Time for draining and line cooling
16”~ 48” (DN400~DN1200)	5-10 man with gasket, tools, lifter & Heavy equipment	by 1man	16~120 man-hours Gasket, bolts & nuts,tools Time for draining and line cooling

Increase productivity

Size	Blinding	Deblinding	More production
1/2”~ 14”	1 to 4 hours	1 to 4 hours	2 to 8 hours
16”~ 48”	4 to 12 hours	4 to 12 hours	8 to 24 hours

Reduce maintenance costs
