Component Specifications

Definition
A vent is a critical component installed on storage tanks to manage internal pressure variations caused by temperature changes, filling, and emptying operations. It allows controlled release of vapors to prevent overpressure or vacuum conditions, ensuring tank structural integrity and safe operation. Vents typically include pressure/vacuum relief valves, flame arrestors, and conservation vents for environmental protection.
Working Principle
Operates on pressure differential principles: when internal pressure exceeds set limits, the vent opens to release vapors; when vacuum conditions occur, it allows air ingress to prevent tank collapse. Conservation vents minimize product loss by only opening at specific pressure thresholds.

Stainless steel (316/304), carbon steel with corrosion-resistant coatings, PTFE seals, aluminum alloys for non-corrosive applications

Frequently Asked Questions

What is the difference between a conservation vent and a regular pressure vent?

Conservation vents have tighter sealing and open only at specific pressure thresholds to minimize product evaporation loss, while regular pressure vents open whenever pressure exceeds set limits.

How often should tank vents be inspected?

Monthly visual inspections and annual performance testing are recommended, with more frequent checks in corrosive environments or high-usage applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
