Working with Gaseous Chemicals
Gaseous Chemicals & Vapour Lock
When selecting pipework for chemicals, consideration needs to be given to both the resistance of the material and its subjectivity to become gaseous.
- Sulphuric Acid
- Chromic Acid
- Hydrochloric Acid
- Nitric Acid
- Sodium Hypochlorite
- Hydrogen Peroxide
- Hydrofluoric Acid.
Gaseous Chemicals may cause a system to discharge inaccurately and vapour lock.
Prevent – Accuvent
Accuvent – This valve is designed to allow for the venting gas and condensed vapour to be returned to feed tank and can be installed on inlet or discharge.
Prevent: Vented Ball Valve Type 546-GVented Ball Valves: Customised ball valve with a small 1/8 inch vent hole.
The hole functions as a vent for media that would normally be trapped inside a closed ball.
The vent prevents potentially dangerous pressure from building up inside the valve.
The valve is installed with this hole facing the upstream side.
Protect – Double Containment
From a safety standpoint, consideration should be given to double containment pipework.
Double Containment – Double containment is a pipe in pipe system and offers safety in your piping system.
PAAS offers multiple containment systems to meet your requirements, please contact our office to discuss.
