Description

Technical Field

[0001] This invention relates to the field of thermal insulation steel pipe cutting technology, specifically a processing device for steel-clad steel thermal insulation steel pipes. Background Technology

[0002] Steel-jacketed insulated steel pipe, also known as steam insulated pipe, is a prefabricated direct-buried pipe composed of a three-layer structure consisting of an inner working steel pipe, an insulation layer, and an outer protective steel pipe. It is mainly used to transport high-temperature media such as steam and hot oil.

[0003] A search revealed a Chinese patent with application number "CN202511041065.5", which specifically describes a processing device for steel-clad steel insulated steel pipes. The device includes a spindle box and a hydraulic drive mechanism. The hydraulic drive mechanism includes a fixed cylinder installed on the top of the spindle box. Both ends of the outer surface of the fixed cylinder are fixedly connected to a connecting pipe. A telescopic rod is installed on the top of the fixed cylinder. One end of the connecting pipe is fixedly connected to a limiting and centering mechanism.

[0004] When processing existing steel-clad insulated steel pipes, both ends of the insulated steel pipe need to be cut.
