Technical processes
MoreCentrifugal Casting
Centrifugal casting serves as the core production process for high - temperature alloy furnace tubes, which typically operate under extreme temperatures in critical sectors such as petrochemicals and energy. Therefore, the density and uniformity of the materials are of crucial significance.
Resin sand static casting
Resin sand static casting is a conventional casting technique that is particularly suitable for the production of high temperature resistant alloys, especially for large castings with wall thicknesses exceeding 15 mm and complex geometries.
Lost wax precision casting
This process utilizes mid-temperature wax patterns and employs high-quality materials such as silica sol, zircon flour, and mullite sand to produce high-strength ceramic molds.
Machining capabilities
Equipped with multiple sets of imported pull-boring and push-boring machines, and integrated with self-developed guiding tooling bars. This combination ensures exceptional machining precision and superior wall thickness uniformity, delivering results that have earned consistent customer acclaim.
Welding
Advanced automated equipment is employed for the welding of high-temperature alloy furnace tubes.
