The bright annealing production line for precision tubes is a continuous, automated production line that performs solution heat treatment on precision cold-rolled (or cold-drawn) tubes while maintaining a bright surface finish. It not only completes the "solution annealing" heat treatment process but also integrates precision heat treatment, surface protection, in-line processing, and quality control into a high-end manufacturing system.
Large diameter welded pipe black annealing machine is a special machine for heating the steel pipe to solution temperature and then cool it to room temperature. Induction annealing machine adopts the advanced induction heating power supply, the new type DSP+IGBT power supply. It uses IGBT inverter, DSP precision control, air-cooling structure( water cooling for induction coil), reduce the loss of system. It has perfect self-protection and self diagnostic function, saves 15% energy comparing with the similar product. It is the first heat treatment furnace that could annealing such large stainless steel welding pipes.
HHS type black annealing machine is a specialized equipment that heats steel pipes online to the solution treatment temperature, and then quickly cools them to room temperature through water spraying. The advanced induction heating power supply is an efficient and energy-saving product with a new DSP+IGBT structure. The product is an IGBT inverter and uses DSP for fully digital precise control, reducing system losses. It is equipped with comprehensive self-protection and self-diagnosis functions, saving about 15% energy compared to similar products.
The coil pipe offline bright annealing line is specially designed for heat treatment of stainless steel coil tubes. The process is carried out in a protective atmosphere to prevent oxidation and maintain the pipe’s bright surface. The line typically includes a loading station, annealing furnace, water cooling section, and gas control system.
With accurate temperature regulation, stable gas flow, and efficient heat distribution, the system ensures uniform microstructure, enhanced corrosion resistance, and a mirror-bright finish. It is suitable for a wide range of pipe sizes and can be customized according to production requirements.
The corrugated pipe annealing production line provides a continuous heat treatment process to restore the mechanical properties and ductility of stainless steel corrugated tubes after forming. The system includes a controlled atmosphere annealing furnace, water cooling section, and automatic material handling system. With accurate temperature regulation and stable conveying speed, it ensures uniform heating and cooling, eliminating residual stress while maintaining the corrugation’s dimensional accuracy. The entire line is energy-efficient, reliable, and suitable for both online and offline operation.
High performance, fast response, and stable positioning of servo motors; Combined with stable hydraulic pressure and high pressure regulation output; Integrating servo and hydraulic advantages. The use of servo motors ensures high-speed, precise, and smooth round-trip of the leveling car. Using hydraulic pressure for fast, stable, and precise pressure compaction of welds, using proportional valves and digital adjustment of pressure on the operation panel, the output is precise and reliable, and the quality of the welding seam is even better.
The HZP double-push series weld seam leveling equipment is an online processing system for welded pipe seams. It simultaneously and repeatedly rolls the inner and outer weld seams of the pipe, making the weld seam smooth and transitioning seamlessly with the base material. This further highlights the advantages of the welded pipe and is a specialized seam welding equipment for improving the crystal grade of the weld seam.
Hangao's welding bead rolling machines have customer recognition and a market share of around 80%. Our leading position is based on a combination of factors: fewer failures, more stability, and a technologically advanced reserve that competitors find difficult to copy.
In order to meet higher requirements for the solid solution treatment process of pipes, we have developed an intelligent insulation type bright solid solution equipment based on intelligent bright solid solution equipment. The equipment is divided into a heating section and an insulation section. During the production process, the pipes are heated to the set solid solution temperature in the heating section, and stabilized for a certain period of insulation in the insulation section, thereby more effectively eliminating the possibility of grain boundary chromium deficiency and avoiding the occurrence of intergranular corrosion. The stabilized pipes have better mechanical properties and corrosion resistance.
