[0001] Waste covering pipe stripping apparatus [0002]

The present invention relates to a closure device for closure of a closure, and more particularly, to a closure device which can conveniently provide a series of work processes for easily introducing and discharging a closure of a closure and easily separating a closure of a synthetic resin material coated on a steel pipe, Which is capable of significantly increasing the recycling effect of the waste clad tube.

In general, the gas piping which is buried underground or sea surface for gas supply (transport) is coated with PE resin on the outer circumferential surface of the steel material for preventing corrosion and durability.
