Thermodynamic Trap for your equipment.

The 1/2" thermodynamic steam trap with strainer is used on equipment. It is best suited for header and main line drains and drip legs. The stainless steel construction ensures better mechanical and corrosion resistance. The disc and seat are hardened by a special process for continuous, prolonged operation. Manufacturers warranty applies.

Features

  • Used on equipment
  • Made from stainless steel

What is a thermodynamic disc trap and why would it be necessary?

Please Note: Your answer will be displayed upon approval.
A:
This trap is typically small and lightweight, as is used where there are space constraints. It contains only 1 operational part, that of the disc itself. It is resistant to hydraulic shock, and will offer complete removal of condensate when opened and operating properly. The disc is opened and will allow condensate to pass when it is present in the trap, if there is steam in the trap; the disc stays closed and will not allow it to escape out of the outlet passage. These traps react quickly to differences in steam and water pressures. They work well with all-steam irons because of the immediate removal of condensate.

My boiler often had the rattle or hammer noise at the water line. I had changed the check valves a couple times but after the month I heard that noise again. The water is low and the pump keep working more than usual when the noise is heard.

A:
Working steam traps are key to preventing water hammer in the lines. A steam trap’s job is to remove water/condensate that accumulates in the line and return it to your return tank.

Why do some valves come with a WSP and WOG rating, and others just talk about the psi ranges?
Anonymous

Please Note: Your answer will be displayed upon approval.
A:
Some valves can be used on water, oil, and air (WOG) as well as steam. Steam is a more abrasive substance, so the WSP (working steam pressure) rating tends to be lower than the WOG rating. Some items, just as steam traps and steam pressure reducing valves are only used in conjunction with steam, so psi ranges are associated with these items.

Where should a steam trap be located?
Anonymous
Posting As
Please Note: Your answer will be displayed upon approval.
A:
Steam traps should be located on the return line after each piece of equipment that is to be drained. Ideally the traps should be installed where they are easily accessible, below the equipment that is to be drained, and in a close proximity to the equipment.

What does a steam trap do?

A:
A steam trap’s function is to “trap” steam and to collect condensate so it will be transferred back into the return line, and back to the boiler where the condensate will be changed into steam.

Why would a trap that seems to be discharging water experience problems when connected to the return line?
Anonymous
Posting As
Please Note: Your answer will be displayed upon approval.
A:
1. If this is experienced, there may be a problem in the return line, back pressure may be diminishing the capacity of the trap: 1. Return line may be too small. If this were the case the trap would be hot. 2. Other traps on the line may be blowing steam. This too would cause the trap to be hot. 3. There may be a blockage in the return line. The trap would be hot. 4. There may be an excessive vacuum in the return line. If this were the case the trap would be cold. The atmospheric vent in condensate receiver may be plugged. The trap could either be hot or cold.

How can I tell if my steam traps are bad?
Anonymous

Please Note: Your answer will be displayed upon approval.
A:
Steam traps from time to time may fail. However, trap failure is not always easy to detect as steam may be blowing back into the pipe. Many experts agree that the best way to test a trap is to install test valves below the steam trap. If steam or nothing comes out of the test valve, then the trap is blown, however is condensate comes out, then the trap is working properly. Another extremely accurate way of testing traps is to use ultrasonic detection. Ultrasonic detectors translate ultrasonic emissions into sounds the human ear can hear. Technicians that use these detectors on a daily basis have an extremely high rate of accuracy. Someone with experience in using this technique should be consulted. The reason that these methods are most often recommended as opposed to temperature measurements, is because of the many different variables in the piping systems that may give inaccurate results about the traps efficiency such as back pressure or strainer and valve problems.

What would cause my pressing unit not to heat properly if the trap seems to be working properly?
Anonymous
Posting As
Please Note: Your answer will be displayed upon approval.
A:
If the unit is not heating properly: 1. The problem may be that one trap is being used to drain more than one piece of equipment. For example, if the trap is trying to work for more than one shirt unit, legger, or utility pressing station at a time, the trap will not work as efficiently. Condensate and air from one of those units may not reach the trap. The solution would be to install a trap on each unit. 2. Another reason this could happen would be if the trap were too small for the job. 3. The trap may have inadequate air handling capacities or air may not be reaching the trap. Try using alternate air vents.

Why would a trap be losing steam if it was just replaced?
Anonymous
Posting As
Please Note: Your answer will be displayed upon approval.
A:
If the trap is blowing live steam, it could be due to: 1. The valve may not be seating properly due to scale or dirt being lodged in the trap or there may be worn or defective parts in the trap 2. The trap may have lost its prime—close inlet valve for a few minutes, and slowly open it back up. The trap should catch its prime. Prime loss is typically due to frequent or sudden drops in pressure.

Why would a steam trap get hot and not release any condensate?
Anonymous
Posting As
Please Note: Your answer will be displayed upon approval.
A:
A. If the trap is getting hot and not releasing any condensate, this would suggest that there is no moisture or condensate making it to the trap. The trap may be installed above a leaky by-pass valve, there may be a broken pipe in the syphon drained cylinder, or there may be vacuum water heater coils that could prevent drainage.

Why would a steam trap be cold?
Anonymous

Please Note: Your answer will be displayed upon approval.
A:
The trap is not discharging any water or condensate. There are a couple of reasons why this would happen: 1. The pressure may be too high. 2. There maybe no water or steam coming to the trap 3. There maybe a defective or worn piece inside the trap not allowing the trap to work properly. 4. The trap body could be filled with scale or dirt 5. The bucket vent, in an inverted bucket trap, may be filled with dirt 6. If it’s a disc trap, the trap may have been installed backwards.

Why do some of the traps have water inside of them when a customer first receives them?

A:
All traps are tested to ensure they are working before they leave the plant. Some condensate from that testing may be left in the trap when being shipped.

What can I do to keep my disc trap functioning properly?
Anonymous

Please Note: Your answer will be displayed upon approval.
A:
First, make sure there is a strainer in from of this trap. Dirt or debris in the trap will keep it from operating properly. You can also clean the trap by removing the cap on it. Inspect the disc to and clean the disc and seating surface in the trap housing. Most the time doing this fixes the problem.
