Cleaning of metal cartridge
OUR SERVICES
Strainer Design & Fabrication
- Scheduled steam trap survey is essential to reduce steam consumption and improve efficiency. Steam system inefficiency causes lost profit in areas such as:
- Steam loss through leaking traps, bypass valve and failed-open trap Strainers are a type of pipe fitting where liquid passes through for removal of solids. Its purpose is to protect critical equipment such as:
- Pumps
- Heat exchangers
- Valves
- Regulators
- Flow meters
- Steam traps
- Other pipingitems
Types of Strainers Available
Y-TYPE STRAINER
Standard sizes from 1/2” to 16”
Economical
Equipped with blow off valve for flushing
Can install horizontally or vertically
Flanged, Buttweld, RTJ, Socket Weld, Threaded connections are available
Standard Materials: Cast Iron, Carbon Steel, SS304, SS316 are standard
materials. Other materials available upon request
Our inspection methods can detect small leaks that is not visible. A proper maintenance program can yield up to 20% in energy savings! We have more than 30 years experience with steam traps and provide quality advice to improve your steam trap performance.
Cleaning of metal cartridge
This document describes the various ways which SS Metal filter can be cleaned
Cleaning of metal cartridge filter
Wedge filter
Pleated filter
- These filters are more expensive than basic strainer filter, therefore it makes sense to clean and reuse
- Methods to clean
1) Spray with Water Jet (Back Flush)
2) Ultrasonic
3) Hot Sand Bath
Ultrasonic Cleaning
ultrasonic cleaning machine
Slight decrease in contaminant capacity results after each cleaning. Close inspection of the screens, for any damage, is key to maintaining proper filtration and performance of the filter.
USE ANY CLEANER/DEGREASER AS RECOMMENDED BY THE SPECIFIC
ULTRASONIC CLEANING APPARATUS.
NOTE: Ultrasonic cleaning is highly recommended for filters having a micron rating of 40 microns or smaller.
Cleaning using Hot Sand
The strainer element (typically metal) is buried or suspended in a bed of hot sand, which is heated to around 400–600 °C. The heat burns off oil, grease, and polymer residues.
Advantages:
- Excellent for burning off heavy organic or polymer fouling (e.g. in plastic, paint, resin, or oil applications).
- Can handle thick carbonized deposits that would be hard to remove chemically.
- No need for solvents or chemicals.
Limitations:
- Only suitable for metallic elements (e.g. stainless steel).
- Can oxidize or warp fine mesh screens if temperature is too high.
- Does not remove inorganic scales or mineral deposits.
- Needs careful control — overheating can damage the mesh or cause grain growth.
Final Notes
- All filter elements have a lifespan.
- Whichever method of cleaing can not remove 100% of all debris
- After many rounds of cleaning, the filter element will become permanently choked and it will be time to replace
- In general, we recommend to clean the filter element when the pressure drop reaches 0.1 – 0.2 bar. Allowing the pressure drop to exceed this may risk the containments becoming permanently stuck in the filter element.
