Multiport & Internal Pressure Relief Valve Replacement

RELIEF VALVE INSPECTION & REPLACEMENT SERVICES

One of the most important safety components of LPG/propane storage vessels is the internal relief valve system.  LP-gas relief valves are intended to open only under the excessive pressure conditions indicated below.  The container pressure will get high enough to open relief valves under the following conditions:

  • Filling containers not purged of air
  • Overfilled container exposed to heat, which includes radiant heat (sun).
  • Use of an incorrect product such as propane in a container with relief valve set for butane pressures (Low set pressure for service)
  • All containers exposed to extreme heat (fire).
  • Excessive pressures created during filling

Typically relief valves should be inspected each time the container is filled but no less than once a year.  If there is any doubt about the condition of the valve, it must be replaced.

ROUTINE INSPECTION & REPLACEMENT ENSURES SAFETY 

Under normal conditions, the useful safe service life of a pressure relief valve is 10 years from the original date of manufacture. 

However, the safe useful life of the valve may be shortened by certain environmental conditions and other factors.  At times, replacement may be necessary much sooner.  Routine inspection and maintenance of pressure relief valves ensures the safe operation of your storage tanks.

TransTech Energy maintains specialized equipment to safely flare off your tanks and quickly replace your internal pressure relief valves.  We will also replace the relief valves on your Multiport assemblies, allowing you to avoid the potential loss of your entire tank's contents through mishandling of this procedure.
