Product catalog summary
Description: The PT40 is a thermostatic steam trap featuring a bimetallic column, an inbuilt strainer, and stainless steel internals. It is ideal for steam tracers, header drip legs, heating coils, and various process and heating applications.
Features: The steam trap includes corrosion-resistant stainless steel protected bimetal plates, excellent resistance to water hammer, adjustable sub-cooling temperature, tight shut-off with no steam loss, long-lasting modulating discharge, and excellent air venting capability. It is suitable for both saturated and superheated steam applications.
Sizes and Connections: Available in NPS ½ and ¾ sizes with connections including Screwed (NPT/BSPT/BSP), Socket Weld, and Flanged. End connection flanges are made of ASTM A105 forged carbon steel and are weld-on.
Limiting Conditions: The maximum allowable pressure (PMA) is 450 psig, and the maximum allowable temperature (TMA) is 800 °F. The maximum operating pressure (PMO) is 315 psig, and the maximum operating temperature (TMO) is 760 °F. The cold hydro test pressure is 675 psig.
Installation: The trap should be installed horizontally with the cover on top and below the drain point. Full port isolation valves should be installed upstream and downstream. Ensure sufficient upstream piping capacity to prevent condensate backup, with a minimum of 1 meter.
Important: For new pipelines, ensure proper flushing before fitting the traps to avoid strainer choke-up.
Available Spares: Controller Assembly, Gaskets, Strainer Screen.
Ordering Information: Refer to the 'How to Order' page.
Dimensions and Weights: Dimensions are provided for sizes ½" and ¾" with weights varying based on connection type (SCR/SW or Flanged).
Material: The steam trap is constructed from materials including ASTM A105 for the body, ASTM A216 Gr. WCB for the cover, Bimetal/SS for the controller assembly, stainless steel for the seat and valve stem, AISI 304 for the strainer screen, and CAF/Graphite with SS304 reinforcement for the gasket. Bolts are made from ASTM A193 Gr. B7.
Note: Local regulations may restrict the use of this product below the quoted conditions. Limiting conditions refer to standard connections only. Specifications are subject to change without prior notice.
