Large diameter API pipe black annealing machine is a special machine for heating the steel pipe to solution temperature and then cool it to room temperature. This 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 machine that could annealing such large stainless steel welding pipes.

Our Advantages
√ No preheating required.
√ Start and stop at any time.
√ Flexible diameter adjustment.
√ Guarantee pipe straightness.
√ Integrated control panel, CNC design, easy to operate
√ Efficiency increased by 50%.
√ Fast heating speed,surface of the workpiece gets evenly heated , and un-easily oxidized.
Function
1. Reduce the hardness of steel pipes, improve the plasticity, to facilitate cutting machining and cold deformation.
2. Fine grains and homogeneous steel organization and composition, to improve the performance of steel, also to make preparation for the heat treatment.
3. Remove the residual internal stress in steel, to prevent deformation and cracking.
Feature
1. No need pre-heating. Comparing traditional black annealing furnace, it only takes 10-15 minutes to reach the exact temperature.
2. No need re-straightening. Using rotary tube delivering structure, there is only tiny deformation after heat treatment.
3. Automatic uploading tubes, with strict docking of front and rear tube's end.
4. Fully automatic running, saving labor cost.
What is induction heating's advantage?
The electromagnetic heating system consists of two parts: the electromagnetic heating control board and the heating coil. The temperature-controlled power supply [heating output contactor (or solid-state relay) output terminal] of the original machine rectifies, filters, and inverts the power-frequency alternating current into high-frequency alternating current through the electromagnetic heating control board, and connects it to the electromagnetic heating coil through the connecting wire. The high-frequency alternating current acts on the metal heated body through the insulation material to make the heated body heat itself. In addition, the power supply can also be directly input to the electromagnetic heating control board, and the original temperature controller directly controls the working state of the electromagnetic heating control board through the soft start interface of the electromagnetic heating controller.
