Description

Technical Field

[0001] The utility model relates to the technical field of petroleum pipeline processing equipment, in particular to a stainless steel petroleum pipeline cutting device. Background Art

[0002] The corrosion resistance of stainless steel pipes makes them suitable for oil and gas wells containing H2S or CO2 and chloride ions. In particular, they can still maintain stable performance under high temperature and high pressure conditions, and have broad application prospects in the oil and gas industry.

[0003] The preparation of stainless steel oil pipelines is a complex process involving material selection, continuous rolling, testing, surface treatment and special process treatment. After the stainless steel pipeline is prepared in sections, the ends of the pipeline need to be cut neatly and a specific shape needs to be cut for subsequent welding of multiple sections of stainless steel pipelines into a whole pipeline. At present, the end cutting of stainless steel pipelines is mainly done by cutting the initial material with a cutting machine, and then manually grinding the end into a specific shape. For pipelines with larger diameters, manual grinding is time-consuming and labor-intensive, which reduces labor efficiency.

[0004] Therefore, technicians in this field are committed to developing a stainless steel petroleum pipeline cutting device, which is conducive to cutting the end of the stainless steel pipeline into a set shape, reducing subsequent grinding, and improving the efficiency of stainless steel pipeline preparation.
