在现代工业领域里,金属管的应甩范围十分广泛,不仅在化工、发电、石油、制药等部门应用于管道系统。完成流体的输送任务,而且也由于管材断面强度的合理性,在结构上的应用也日益增多,尤其在自行车、汽车、工程机械、农用机械、飞机、家用电器等方面的应用,令人瞩目。 In the field of modern industry, metal tubes should be used in a wide range of applications, not only in the chemical, power generation, petroleum, pharmaceutical and other departments in the pipeline system. The completion of the task of conveying fluid, but also due to the rationality of the strength of the pipe section, the structural applications are also increasing, especially in bicycles, automobiles, construction machinery, agricultural machinery, aircraft, household appliances and other aspects of the application, attracting attention.
