Proper steam line design & maintenance is an important consideration for a well functioning steam injection heating system. The quality of steam entering the heater can have a direct impact on the heater’s performance and frequency of maintenance intervals.
- Smooth & stable steam injection heater operation
- Reduced wear life of steam injector components
- Improved steam quality being delivered to the heater.
- Fewer process upsets.
Typical Steam Piping Design Lay-out & Recommended Components
Important Steam Line Design Components
- Steam Isolation Valve – The steam isolation valve can be tied into alarm conditions such as loss of flow, Hi-temp alarm, and for when the steam injection heater is not in use or maintenance is being performed.
- Steam Trap & Drip Down Leg – Removal of condensate prior to the heater can help to eliminate rough operation and noise. Excessive condensate can lead to pre-mature wear of steam injector components.
- Steam Strainer – Foreign particulate, rust, and tram material can
- Check Valve - .This helps to prevents fluid from flooding the heater & steam line when not in operation. Excessive fluid backing up into the steam line needs to be evacuated upon start-up and can lead to rough operation & wear of steam injector components.
