Frequently asked questions about tank sandblasting, internal/external surface preparation, ventilation, SA levels and safe field execution.
How is internal tank sandblasting planned?
Tank volume, access method, ventilation capacity and target SA level are confirmed during survey; confined space HSE procedures are defined at project start.
What is included in external tank sandblasting scope?
External steel rust/coating removal, dust control, access scaffolding coordination and pre-coating profile verification are defined per project scope.
Which SA cleanliness grade is targeted?
SA 2.5 is typically targeted according to coating system and specification; SA 2 or SA 3 is confirmed against technical requirements.
How is ventilation provided for internal tank blasting?
Confined space ventilation, air exchange rate and dust collection equipment are planned per tank volume and HSE rules.
How is dust control managed on tank projects?
Dust collection equipment, environmental barriers and working hours are planned per site rules and environmental requirements.
Is pre-coating surface verification performed?
Yes. Cleanliness grade and surface profile are verified on site against agreed SA/SSPC criteria.
How is blasting duration determined for maintenance projects?
Tank quantity, access conditions, target SA level and coating window are evaluated together for a phased application schedule.
What information is needed for a quote?
Tank type/volume, internal/external scope, target date range, estimated quantity, target SA level and access constraints speed up quotation.
