About this file
This document contains technical information for a thermodynamic steam trap and related details for a federal contract opportunity to remove and replace hot water heaters. The federal contract opportunity is to provide all labor, materials, specialized equipment, transportation and supervision to remove two existing hot water heaters with associated valves and traps and replace them with two instantaneous steam water heaters, valves, traps, piping and associated parts at an agricultural research facility. The work is to be completed at Building 010A Mechanical Room B2R4 and optionally at Building 001 Mechanical Room. A mandatory site visit is required to attend. Any questions must be submitted in writing to the point of contact by July 21, 2022 in order to receive a response, as questions submitted after may not be answered prior to the quote submission.

Model TD52
PMO 600 psig
Sizes 3/8”, 1/2”, 3/4”, 1”
Connections NPT
Construction stainless steel
The Thermodynamic steam trap cycles periodically to discharge condensate very near to steam temperature.
It is unaffected by waterhammer or superheat.

Thermodynamic Steam Trap
TD52
Maintenance This product can be maintained without disturbing the piping connections.
Complete isolation of the trap from both supply and return line is required before any servicing is performed.
The trap should be disassembled periodically for inspection and cleaning of the disc and seat.
The only wearing parts of the trap are the disc and seat rings, which should be inspected and cleaned periodically. Slight wear can often be corrected by resurfacing on a lapping plate.
Caution: Only perform maintenance after trap has been isolated.
Complete installation and maintenance instructions are given in IM-2-516-US, which accompanies the product.
Installation The preferred installation is in the horizontal position as close as possible to equipment being drained. Install strainer (20 mesh) upstream and full port isolating valves upstream and downstream of trap. Piping to and from the trap should be at least equal to or one size larger than trap connection. Do not weld pipe connection to trap. Body material is not suitable for welding.
For freeze resistant installations, all drains must be pitched toward the trap for gravity flow. Trap must be installed vertically, dis-charging downward. Discharge piping must be self-draining.
