We can conduct a full steam system audit comprised of:
- Full Steam Trap Studies
- Check Piping for Heat Sinks
- Check Heat Exchangers for present stall conditions.
Audits start in the boiler room and follow steam piping to process and back to the feedwater tank or DA.
A custom booklet will be constructed for each facility comprised of 5 sections including:
- Steam System Description,
- Observations & Recommendations
- Priority Repair List
- Trap Audit
- Reference Section.
We then set a meeting to review the booklet and its findings with the customer.
Steam Audit Scope:
- All traps will be tagged and checked for proper operation.
- Steam traps will be sized and recommendations will be given for energy efficient traps.
- Steam piping will be checked for proper sizing and location of drip legs & clean outs.
- Estimated savings will be calculated from present fuel, water cost and current boiler run time.
- Boiler room efficiency estimates will be compiled and listed.
- Visually Check the operation of the DA, Feed water Tank and list findings.
- Recommendations will be given for any safety related items viewed.
- Estimated repair cost will be compiled and presented in the custom facility booklet in conjunction with estimated savings.
Samples of various Audit Observations:
The Feed Water Tank’s steam pre-heat valve does not have a drip leg and trap up stream.
Removing the condensate will make the valve control more accurately.
Condensate can eventually destroy the seat in the valve.
Adding a drip leg and trap is recommended
The main steam header in the boiler room does not have a drip leg
and a trap before the main 100 PSI knock down regulator.
High pressure steam should come from top of the pipe.
This header has an elevation change on the high pressure main.
Recommend installing drip leg, trap and clean-out
Steam Audit Samples:
Properly evacuating condensate from a steam system.
This will improve steam quality and can prevent steam expansion (water hammer) causing vessels to rupture and valve or piping issues.
Installation of properly sized and properly placed drip legs & traps with clean outs are recommended on every elevation change.
All steam system drip legs should be properly sized and have clean outs installed.
These clean outs can be drilled and tapped for 1/2” NTP, or flanged clean outs with steam rated ball valves added
for blow down on 4 to 6 month intervals to remove any excess debris.
Traps with strainers can be blown down under this PM type procedure also.
Over time leaks develop causing oxygen to enter the steam and condensate system, this can cause carbonic acid.
Carbonic acid can cause internal pipe and equipment erosion or failure.
