Working with Gaseous Chemicals

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.

Examples of Gaseous Chemicals:
  • 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.

One solution is to ensure the system is properly vented, thus preventing a vapour lock occurring.
The following products available from PAAS can assist.
 

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

The gaseous chemicals listed above are also highly hazardous.
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.
