ARMSTRONG INTERNATIONAL

Armstrong International is a manufacturer of steam system components, with a product line that includes steam traps, air vents, and steam spargers. The company's history dates to the early 20th century, and its engineering focus is on condensate management and heat-transfer efficiency in industrial steam systems. Armstrong's product families cover inverted-bucket steam traps, float and thermostatic traps, thermostatic air vents, and steam spargers, among others. These components are used in applications such as process heating, steam distribution, and hot water generation across industries including chemical processing, food and beverage, refining, and commercial HVAC. Armstrong components are built to recognized standards; for example, their cast-iron steam traps are rated for pressures up to 250 psi and temperatures up to 450°F, while stainless-steel corrosion-resistant traps handle up to 650 psi and 800°F. Inlet connection types include NPT and FNPT in sizes from 1/2 inch to 1 1/4 inch. The inverted-bucket design is known for its ability to handle varying condensate loads and resist damage from water hammer. Armstrong also offers steam spargers made from 304 stainless steel for direct steam injection into hot water media. 3G Electric supplies a range of Armstrong International products, including standard and corrosion-resistant inverted-bucket steam traps, as well as steam spargers. The inventory covers multiple pressure and temperature ratings, with options for integral strainers. For procurement specialists and plant engineers, Armstrong components provide predictable performance in steam systems where reliability and condensate removal are critical. 3G Electric supports global sourcing of these items, with technical specifications available for each SKU to aid in selection.

Frequently asked questions

Common questions about ARMSTRONG INTERNATIONAL from 3G Electric.

What is the operating principle of Armstrong International inverted-bucket steam traps?

Armstrong inverted-bucket steam traps operate on the principle of density difference. When steam enters the trap, the bucket floats and closes the valve. Condensate and air cause the bucket to sink, opening the valve to discharge. This design provides continuous condensate removal and is resistant to damage from water hammer or dirt. The traps are available in cast iron for pressures up to 250 psi and stainless steel for pressures up to 650 psi.

What materials are used in Armstrong International corrosion-resistant steam traps?

Armstrong corrosion-resistant inverted-bucket steam traps are constructed from stainless steel, typically 304 or 316 grades. These materials provide resistance to corrosive condensate and high-temperature environments. The traps are rated for pressures up to 650 psi and temperatures up to 800°F, making them suitable for applications where standard cast-iron traps would degrade.

How do Armstrong International steam spargers work?

Armstrong steam spargers are devices that inject steam directly into a liquid, typically water, to heat it. The sparger is made from 304 stainless steel and has a pipe size of 1 1/4 inch with NPT connections. It is designed for hot water media and operates by distributing steam through multiple orifices to minimize noise and vibration while achieving efficient heat transfer.

What is the maximum pressure rating for Armstrong International cast-iron steam traps?

Armstrong cast-iron inverted-bucket steam traps are available with maximum pressure ratings of 125 psi or 250 psi, depending on the model. For example, the 883-125-125 model is rated for 125 psi, while the 883-075-250 model is rated for 250 psi. These traps also have a maximum temperature rating of 450°F.

Do Armstrong International steam traps include integral strainers?

Some Armstrong International steam trap models include integral strainers, while others do not. For instance, the 882-050-125 and 883-125-125 models include strainers, whereas the 811-050-125 and 1811-050-200 models do not. The product specifications indicate whether a strainer is included, allowing selection based on system requirements.

What connection sizes are available for Armstrong International steam traps?

Armstrong International steam traps are available in FNPT connection sizes ranging from 1/2 inch to 1 1/4 inch. Common sizes include 1/2 inch, 3/4 inch, 1 inch, and 1 1/4 inch. The traps are designed for horizontal installation and in-line configuration.
