A billet is a length of metal that has a round or square cross-section, with an area less than 36 in2 (230 cm2). Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. Billets are further processed via profile rolling and drawing. Final products include bar stock and wire. Centrifugal casting is also used to produce short circular tubes as billets, usually to achieve a precise metallurgical structure. They are commonly used as cylinder sleeves where the inner and outer diameters are ground and machined to length. Because their size is not modified significantly, they are not always classified as semi-finished casting products.

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.

A series of studs are welded on the surface of the steel pipe by the studded tube automatic welding machine to strengthen the heat exchange components, which is characterized by: 1. The square circumference is welded equally; 2. The hexagonal circumference is welded equally. Compared with the traditional studded tube manufacturing process, the square and hexagonal studded tubes strengthen the heat exchange elements, which are formed by welding at one time. The phenomenon that the welding stud falls off after the welding is forced to stretch by tooling in the past has been changed, so that the studded tubes are welded more firmly and the welding stud is not easy to fall off. The welding studs, diameter, length, longitudinal spacing, number of circumferential welding stud and angle of inclination of welding stud are all factors affecting heat transfer of studded tubes. Therefore, it must be considered systematically to be more practical. The square and hexagonal circumferential welding and stud shaped tubes are used to arrange the welding and stud shaped tubes equally, which have a larger expansion surface, and the stud shaped tubes have a disturbing effect on the fluid, which can greatly improve the heat transfer coefficient, especially suitable for the enhanced heat transfer of high viscosity oil products, heavy oil and other medium.
Spiral wound finned tubes or crimped finned tubes spiral wound on the base tube, without welding, but spot welding at the end. Material of spiral wound finned tube or crimped finned tube: the finned strip can be copper, carbon steel, stainless steel, non-ferrous metal tube and fin, or it can be root welded or completely welded. Spiral crimped stainless steel finned tube. Spiral tension wound finned tubes for air coolers. Due to the high corrosion resistance of stainless steel, when the environment has certain corrosivity or cleanliness, such as climate industry, heating, drying and cooling, stainless steel crimped fin tubes can be widely used. Usually used for finned tube heat exchangers. The maximum working temperature is 180 â??. Compared with L-shaped finned tubes, spiral wound finned tubes or crimped finned tubes provide higher air side turbulence and heat transfer due to fins curling. Material standard of crimped fin tube: both base tube and fin can be carbon steel and stainless steel Carbon steel: A179, A192, SA210 Gr A1/C, A106 Gr B Stainless steel: TP304/TP304L, TP316/TP316L
