Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of heat shrinkable sleeves, and particularly to a heat shrinkable sleeve heating device. Background Art

[0002] The heat shrinkable sleeve series products are designed for the anti-corrosion of welded joints of buried and overhead steel pipelines and the heat preservation of heat preservation pipelines. They can also be used for the sealing and anti-corrosion of pipeline flange connection parts and collar parts. It is composed of a radiation cross-linked polyolefin base material and a special sealing hot melt adhesive. The special sealing hot melt adhesive can form good adhesion with the polyethylene base material, the steel pipe surface and the solid epoxy coating. When the heat shrinkable sleeve is in use, it needs to be heated by a heating device. Since the heat shrinkable sleeve heating device of the prior art has no protection device, when it is placed after use, dust is likely to enter its interior, and the internal components are likely to be damaged. Moreover, when in use, due to the high temperature of the heating gun, it is likely to scald the placement position when placed. For this reason, we propose a heat shrinkable sleeve heating device.
