WTR Assists China's Military Industry - Heating High Strength Steel Pipe Pre Weld Preheating+Post Weld Hydrogen Removal

        Some people say that being conscientious in their posts is to serve the motherland and to make contributions to the country. Vitre people believe that although the heating industry is small, it is absolutely indispensable, and the industrial development is inseparable from efficient, energy saving, safe and environmental friendly electromagnetic induction heating. Similarly, heating steel pipe preheating before welding and hydrogen elimination after welding, can provide heating solutions for the national military units can not be separated from the efforts of each staff member.

At the end of 2022, a supplier found our company, and Manager Wang was in charge of the whole service of the project. From the bit test, to the detail communication, seriously and responsibly understand the needs of customers, to assist customers to meet a number of requirements, but also intimate recommended for customers to design the open and closed induction heating head. Greatly facilitates the efficiency of the workpiece heating.

        The following are the customer's requirements and our solutions. In order to protect customer privacy, everything involving customer information is omitted. If you have similar working conditions and need to consult, welcome to call or come to discuss business.

1. Party A's needs

1. Heating workpiece: pipe

2. Material: high-strength steel, 30CrMnSiA

3. Heating purpose: preheat before welding and remove hydrogen after welding

4. Temperature requirement: 250℃-- 400℃

5. Heating speed: average 50℃ / min temperature rise

6. Preheating insulation requirements: preheating insulation device is equipped with operation panel, which can display temperature and insulation time through digital display screen; various buttons or switches are set on the operation panel to adjust and control the heating device and temperature parameters. Requirements are as follows

① Preheating function, manually set the preheating temperature through the panel, and the heater will automatically heat up to the preheating temperature

② Thermal insulation function, manually set the temperature and time of insulation through the panel, heater automatic insulation, insulation time is complete, automatic stop.

7. Other requirements: 8 m distance of main engine extension, 2 m distance of extension distance of sensor, infrared temperature measurement range: 1000mm (50mm)

2. Party B scheme -- WTR-SF60-WX Super audio induction heater

According to the work piece size and technical requirements of Party A, and after the calculation by the thermal engineer of Party B, it is preliminarily determined to select the 60KW ultra-audio water-cooled heater, and the sensor shall be configured according to the size of the workpiece.(The following dimensions are for reference according to the actual size)
