Inlet Tubes & Orifices

Inlet Tube

Stealth produces high quality inlet tubes (also known as venturi tubes) for use with burners of a non-tubular design. The function of the tube is to mix gas and primary air and deliver the mixed gas to a burner assembly for combustion.

Inlet tube design is critical to the performance of a burner. An improper design can lead to poor combustion, flash back and many other undesirable characteristics. The Stealth team offers diverse experience crafting units from a variety of tube diameters and materials and is qualified to assist you in meeting your most demanding performance expectations.

Design options

•	The majority of inlet tubes have a shutter designed into them for the precise adjustment of primary air into your burner. These shutters generally locate the orifice for proper concentricity.
•	Inlet tubes may be supplied with a flange for convenient bolting onto a mating part or non-flanged for welding directly to a pan burner or similar unit.
•	Inlet tubes may be constructed with or without a venturi feature - a funnel shaped element that aids in the mixing of gas and primary air.
