Boiler HeaderThe plasma flame cutting technology is used to process the intersecting line of boiler header nozzles. This cutting machine is able to read the saddle value of intersecting line directly with no error. Alloy steel material and welding lines are analyzed by spectrum analyzer and the analytic data are displayed on the screen which is convenient for follow-up verification. Boiler header butt welds are processed by automatic submerged arc welding technology,Website:http://www.chinawasteheatboiler.com, which lowers working intensity, shortens processing cycle and improves product quality, with the non-defection-welding line pass rate near 100%.
