在二十年代,美国工程师哈里·邦迪先生(Harry Bundy)多年致力于钢管研究,终于发明了一种新型钢管,满足了汽车工业的需要。这种钢管就用他的名字命名为邦迪管。邦迪钢管(Bundyweld Steel Tube)又称铜焊钢管或双层卷焊管。它是用高精密的双面镀铜钢带经过轧机卷轧制成双层管型,然后送入还原性气氛的(火千)焊炉中,以双层管壁360°结合面上的铜为(?)料焊接为一体而成,这一工艺技术成为国际邦迪家族的专利技术。邦迪钢管的生产和检验目前是依据以下
In the 1920s, American engineer Harry Bundy devoted many years to the study of steel pipes and finally invented a new type of steel pipe that met the needs of the automotive industry. This kind of steel pipe was named Bondi tube by his name. Bundyweld Steel Tube is also called brazed steel pipe or double coil welded pipe. It is a high-precision double-sided copper coated steel strip rolled through a rolling mill into a double tube type, and then fed into a reducing atmosphere (Hot Thousand) soldering furnace, with a double-walled 360° joint face copper For the (?) material welding as a whole, this process technology has become the international Bondi family of patented technology. Bondi steel production and inspection is currently based on the following
