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.
