Requirements for welding process of heat transfer oil boiler
Heat transfer oil boiler belongs to industrial boiler, which has been applied in many industries. In order to ensure the application of this equipment, we need to pay attention to various requirements in the welding process. What are the specific requirements? The following is a brief introduction:
In general, the longitudinal girth weld and head joint of heat transfer oil boiler drum are 100% ray or% ultrasonic plus at least 25% radiographic inspection, which is basically consistent with the requirements of current steam boiler and hot water boiler regulations. Only the provision that 100% ultrasonic inspection plus at least 25% radiographic inspection is allowed is added, which is the same as the requirements of 80 edition steam boiler code. This regulation mainly considers 100% ultrasonic and 25% radiographic inspection, which can completely detect the defects in the weld, meet the safety requirements and reduce the production cost. 25% radiographic inspection must include longitudinal seam and circumferential seam cross joint.
I believe that through the above description, we have a deeper understanding of the welding process of heat transfer oil boiler production. If you want to know more about heat transfer oil boiler, please continue to pay attention to our website.
