3. Circulating cooling system
Cooling water is a soft water circulation system. It can be reused without wasting resources and replaced once in about a year. Therefore, the maintenance cost is low.

4. Gas control system
The system is used for continuous bright annealing equipment in stainless steel tubes under controlled atmosphere. Unique gas protection device consisting of argon and hydrogen gas supply inlets, each with a pressure reducing valve and pressure gauge, as well as a flow regulator and flow meter.

5. Temperature control system
At the outlet of the induction heating channel, an infrared thermometer is installed to measure the temperature of the steel pipe. The thermometer is connected to the temperature display and the regulator, and the alarm temperature can be set as required. The regulator is used to adjust the power of the intermediate frequency power supply while ensuring a constant temperature of the steel pipe at different welding speeds. (Or you can provide the relevant signal, the corresponding button is installed in the console of the tube set, it is easy to control.)

Equipment size
According to the customer's required pipe speed and steel pipe specifications, the power of the equipment is adjusted. The higher the power and the larger the wall thickness, the longer the cooling tunnel of the equipment will be. The specific size requires detailed consultation.

Energy consumption description
In the stainless steel welded pipe industry, to make high-quality products, ASTM A249 in the United States clearly states the technical conditions of solution treatment, so it is an indispensable process. The advantage of Hangao Tech (SEKO Machinery) is that the complete set of bright solution annealing equipment with induction heating  is very cost-effective and can completely replace imported equipment.

Every time the finishing tube is rolled, it must go through the process of solution treatment. Ta ensure that the performance of the steel pipe meets the technical requirements. and to provide guarantee for the post-process processing or use. Bright solution treatment process of ultra-long seamless steel pipe has always been a difficulty in the industry.

Traditional electric furnace equipment is large,covers a large area, has high energy consumption and large gas consumption, so it is difficult for realize bright solution process. After years of hard work and innovative development, the use of current advanced induction heating technology and DSP power supply. Precision control of heating temperature to ensure that the temperature is controlled within t2C,to solve the technical problem of inaccurate induction heating temperature control. The heated steel pipe is cooled by "heat conduction"in a special closed cooling tunnel, which greatly reduces the gas consumption and is more environmentally friendly.
