Description

Novel tube drawing device

Technical Field

The utility model relates to the technical field of tube extractors, in particular to a novel tube extractor.

Background

The pipe is used for parts for conveying various fluids in the pipeline. The tubes are generally circular in cross-section, and there are shaped tubes that are made with non-circular cross-sections. Some metal pipes such as steel pipes and copper pipes may also be used as structural or decorative elements. The materials for manufacturing the tube are many, and metals such as steel, iron and copper, and non-metals such as ceramics, plastics and rubber are commonly used. The tube may also be made of a composite of metal and metal or metal and non-metal.

Pipe broadly refers to a pipe used in a pipeline to transport various fluids. The common parts include cast iron pipes, steel pipes, nonferrous metal pipes, nonmetal pipes, plastic pipes, etc. Typically, the tubes are circular, and there are shaped tubes that are made with non-circular cross-sections. The materials for manufacturing the tube are many, and metals such as steel, iron and copper, and non-metals such as ceramics, plastics and rubber are commonly used. The plastic pipe is taken as an important component of modern chemical building materials, and is widely accepted by the majority of users due to the excellent performance, sanitation, environmental protection, low consumption and the like.
