Frequently asked questions about sandblasting at refinery facilities, shutdown planning, standards compliance and field safety.
How is sandblasting planned during refinery shutdowns?
Shutdown schedule, critical area priority and coating window are evaluated together. Scope is phased; mobilization and quality verification follow this timeline.
How is blasting safety managed near live units?
Explosive atmosphere risk assessment, permitted work areas, dust control and site traffic plans are defined at project start.
Which SA cleanliness grade is targeted?
SA 2, SA 2.5 or SA 3 is targeted according to coating system and project specification; selection is confirmed during survey.
What is included in internal tank sandblasting scope?
Ventilation, access, abrasive selection, dust collection and surface profile verification are defined per project scope.
How is dust control managed on refinery projects?
Dust collection equipment, environmental barriers and working hours are planned per site rules and HSE requirements.
Is pre-coating surface verification performed?
Yes. Cleanliness grade and surface profile are verified on site against agreed quality criteria.
Can mobile blasting equipment be used at refinery sites?
Yes. Mobile units can execute tank surrounds, pipelines and unit-based applications where access allows.
What information is needed for a quote?
Site location, work area definition, target date range, estimated quantity, target SA level and access constraints speed up quotation.
