Global precision steel tube manufacturers are accelerating the upgrade of continuous bright annealing production lines, and mesh belt bright annealing furnaces have become a preferred solution for stainless steel and alloy pipe processing, according to the latest heat treatment equipment industry report.
The mesh belt bright annealing furnace adopts a fully sealed furnace body and controllable protective atmosphere, commonly using dissociated ammonia or nitrogen-hydrogen mixed gas. It delivers continuous heating, heat preservation and oxygen-free cooling for cold-drawn steel tubes. This process effectively eliminates residual stress, restores material ductility, and produces scale-free, oxide-free bright tube surfaces without post-polishing treatment.
Traditional batch furnaces often suffer from uneven temperature distribution, unstable surface finish and low production efficiency. The upgraded mesh belt furnace applies multi-zone independent PID temperature control, with temperature accuracy controlled within ±3℃. The high-temperature alloy mesh belt ensures stable transmission for long-term continuous running. With optimized thermal insulation structure, the overall energy consumption can be reduced by over 22% compared with older models.
Equipment suppliers point out that demand mainly comes from manufacturers of precision welded pipes, instrument tubes and fluid transmission tubes. Buyers from Southeast Asia, the Middle East and Latin America are actively sourcing such furnace lines to replace outdated heat treatment equipment. As downstream industries raise requirements for corrosion resistance and surface consistency of steel tubes, the intelligent bright annealing mesh belt furnace with atmosphere online monitoring and remote diagnosis functions will gain wider market penetration in the next few years.
