The economic and technical importance of specialized repair of boiler tubes and furnaces in Fars
Understanding boiler tubes and common damages in boiler tubes
1. Corrosion and oxidation
4. Thermal and Mechanical Fatigue
Technical steps of specialized boiler tube repair
Step 1: Initial Inspection and Diagnostics (NDT)
- Ultrasonic test (UT): to accurately measure the remaining thickness of the pipe wall.
- Penetrating liquids (PT) and magnetic particle (MT) test: To identify surface cracks at welds and tubesheet joints.
- Thickness measurement and visual inspection (VT): To check the amount of deformation, bellying or perforation Pipes.
Second stage: emptying, cutting and removing the worn pipes
The third step: preparing the tube sheet and the position of the tubes
The fourth stage: joining, waltzing and specialized welding
The fifth stage: hydrostatic test and operation
