Internal Thread High pressure boiler Rifled tube is one kind of endophragm processes the spiral line the seamless steel pipe. Main application in on capacity utility boiler's water cooling wall. Usually with the fluorescent tube which uses compares, it can maintain the nuclear ebullition condition under the high fever load operating condition, thus avoids sending the filming condition ebullition, prevents the pipe to burn out, lengthens the pipe service life.
