Line Blanking or Blinding
Stop a process flow by placing an obstruction in the line. Prevents release of combustible and toxic materials, vapors or gasses into the work area.
When do we Blank or Blind?
• Confined Space or Vessel Entry• Process Control
• Commissioning or Startup• Maintenance
• Repairs• Welding
• Extended Shutdown
Blanking/Blinding(the 1980s Way)
Pipe Size Personnel Needed
Hours Tools
½”-14” 2-4 1-4 Gaskets, Nuts Bolts, Tools, Hoisting Apparatus
16”-60” 4-10 1-12 Gaskets, Nuts Bolts, Tools,Hoisting Apparatus
It’s a New Century - Blanking/Blinding With a
Line Blind Valve
Pipe Size Personnel Needed
Hours Tools
½”-60” 1 20 seconds to 5 minutes
Absolute Shutoff
Quick Change
One Operator
No Line Spread
Cost Saving
No Tools
Safe
Simple Structure
Parts and WarrantyStandard Maintenance is gasket replacement.
All gaskets can be replaced at site
Replacement period of seal ring can be different by gasket kind and working conditions
Double Lock System
Handle is secured by SS chain and locked in double so it’s safe even by extreme vibration
Optional Double Sealing
When first O-ring is damaged, second O-ring keep safe (prevent leakage) and as standard dimension it can be easily purchased anywhere in the world
Part Descrip-tionSafety Features
Bleeder connection
This bleeder is able to drain out fluid remaining in the line before operation
Automation
Remote control is available with automated operation like other conventional control valves.
