The present invention relates to the technical field of anti-
corrosion and
thermal insulation pipe cutting, and in particular, to a portable anti-
corrosion and
thermal insulation pipe cutting device, comprising a bracket, a spring telescopic rod and a
handle, etc.; two spring telescopic rods are fixedly connected to the upper surface of the bracket; the telescopic ends of the two spring telescopic rods are commonly fixedly connected to a
handle; and a driving button is provided on the
handle. The present invention surrounds the outer sleeve of the anti-
corrosion and
thermal insulation pipe with a continuously rotating
cutting blade, cuts off the part of the outer sleeve of the anti-corrosion and thermal insulation pipe that needs to be
cut off, and then inserts an arc-shaped cutter into the thermal
insulation layer of the anti-corrosion and thermal insulation pipe and surrounds the thermal
insulation layer of the anti-corrosion and thermal insulation pipe. The blade and high temperature of the arc-shaped cutter are used to melt the thermal
insulation layer of the anti-corrosion and thermal insulation pipe and quickly solidify to form a smooth cutting surface. Compared with cutting by a manual handheld
angle grinder, this not only has a fast cutting speed, a smooth cutting surface, and a clean cutting process, but also will not cause damage to the working steel pipe of the anti-corrosion and thermal insulation pipe, affecting the service life of the working steel pipe.
