自上世纪七十年代我国生产高频焊管以来,生产高频焊管的设备就不断完善和提高,对高频焊管的工艺要求也越来越高,越来越多样化,随着我国经济的飞速发展,对无缝钢管的需求越来越强烈,高频焊管激烈的市场竞争,和对生产成本降低的要求,使高频焊管无缝化成为一种趋势。(1)什么是高频焊管无缝化。顾名思义就是把高频焊管的内焊筋,用机械设备把它去除,再由热处理工艺进行处理加工,使其达到我们 Since the seventies of last century, China’s production of high-frequency welded pipe since the production of high-frequency welded pipe equipment continues to improve and improve the high-frequency welded pipe process requirements are getting higher and higher, more and more diverse, with China’s rapid economic Development, the increasingly strong demand for seamless steel tubes, fierce competition in the market of high-frequency welded pipe, and lower production costs, making high-frequency welded pipe seamless become a trend. (1) What is seamless high-frequency welded pipe. As the name suggests is the high-frequency welded pipe welding, mechanical equipment to remove it, and then by the heat treatment process for processing, so that it reached us
