Radiant tube
what is a radiant tube A radiation tube is a tube extending straight from the center in all directions.It refers to a non-central pipe (or dry pipe) which conveys the material action of the dry pipe to a designated or non-designated address.Radiation tube is widely used in heating furnace and is the main heating element of heating furnace. Application of alloy The radiant tubes are working at high temperature environment on average: 800-120 C, most of them are used for indirect heating to furnace like CAL (continuous annealing line) CGL (continuous galvanizing line). Process of alloy Centrifugal/spun casting method for tube sections, investment casting or sand casting for the bends, hangers, welding and machining Material of alloy High Nickel and high Chrome heat resistant alloys, Cobalt base alloys, like.

Radiant tubes are specialized high-temperature heating components designed for indirect heating in industrial furnaces, kilns, and heat treatment systems. Made from heat-resistant alloys such as HK40 (25Cr-20Ni) or similar grades, these tubes withstand operating temperatures exceeding 1100°C while resisting oxidation and creep. Widely used in steel annealing, petrochemical processing, and non-ferrous metal heat treatment, radiant tubes are critical components in energy-efficient furnace designs, offering superior temperature uniformity and reduced atmosphere contamination compared to direct-fired systems.
