Boiler Parts Steam Drum Made of SA516-70 for Sugar Mill in ASME Standard
Definition
The boiler steam drum is the most important pressure vessel in industrial boilers for storing hot water and steam. In an industrial boiler pipe system, not all hot water can be fully evaporated into steam, but rather, a mixture of steam and hot water. Because saturated hot water needs more heat for conversion into steam, a boiler steam drum is a required piece of equipment. The steam drum separates hot water and steam, where the mixture still flows back for reheating through a down comer.

Accessories
The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump. In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions.
Quality Control
1. Impact test and Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube and electrode
3. X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler
4. Hydraulic test report: ensure the standard working pressure and safety
