How the Products Work Together
- The breather valve handles routine pressure and vacuum generated by tank operation.
- The emergency vent supplies additional relief capacity for the specified abnormal condition.
- The flame arrestor addresses a defined flame-propagation risk at the selected location.
- The strainer removes debris from liquid transfer lines before sensitive equipment.
- Inspection access and maintenance intervals support continued equipment performance.
These devices perform different functions. One product should not be assumed to replace another without a complete engineering review.

Oil & Gas and Tank Farm FAQ
Why does a storage tank need a breather valve?
A breather valve provides controlled pressure and vacuum relief during filling, emptying and thermal breathing while remaining closed within its designed operating range.
Can a breather valve replace an emergency vent?
They normally address different operating conditions. Normal and emergency venting requirements should be evaluated separately before the equipment is selected.
Does every storage tank require a flame arrestor?
No. The requirement depends on the vapor properties, ignition risk, flame scenario, installation location, vent arrangement and applicable project requirements.
Where should a flame arrestor be installed?
The correct location depends on whether the device is intended for end-of-line or in-line service and on the defined deflagration or detonation scenario.
How is an emergency vent sized?
Sizing is based on the required emergency relief capacity, allowable tank pressure, stored product, abnormal scenario and applicable project criteria.
Which strainer is suitable for an oil terminal?
The choice depends on flow rate, debris load, required filtration, allowable pressure drop and whether the line can be stopped for basket or screen cleaning.
How often should tank protection devices be inspected?
The interval should reflect the product, fouling tendency, corrosion conditions, operating history, site procedures and applicable inspection requirements.
What information is needed for a quotation?
Provide tank limits, stored product, flow rates, set points, emergency demand, flame-protection requirement, pipe size, materials and project specifications.
