Cast Tubes for All Furnace Types
EQI offers a wide range of tube styles and material options, along with sizes to match the requirements of leading furnace brands.
Straight Tubes
Provide direct heat and are engineered for durability under axial stress.
U-Shaped Tubes
Designed for compact furnaces where return flow is required within a confined space.
W-Shaped Tubes
Used in high-efficiency applications where greater surface area and compact burner placement are critical. Their triple-leg configuration promotes even heating and stability.
P-Shaped Tubes
Utilized in box-type furnaces, P-tubes are bent at one end and flanged or sealed to direct gas flow efficiently.
Double-Pass or Multi-Pass Tubes
Ideal for maximizing heat transfer in long continuous furnaces.
