Internal spraying machine

Internal spraying process is an indispensable condition for steel pipe to transport clean gas energy, petrochemical energy and water. The structure of internal spraying machine is similar to that of internal shot blasting machine and internal purging machine. The nozzle is installed at one end of the long cantilever, which is driven by the trolley to spray the whole length of the rotating steel pipe. The raw material for internal spraying is usually liquid epoxy.
