FP系列氧气管道阻火器和FPV氧气管道阀门前、后阻火器是我公司与治金部五大钢铁设计研究院和治金部建筑研究总院共同开发的又一产品，在国际焊接专家曾乐教授的亲自指导下成功的解决了不锈钢或碳钢与铜两种金属焊接的难题，填补了国内空白，完全可替代进口。

FP series oxygen Pipeline Fire and FPV oxygen of pipeline valves before and after the flame arrester is my company with metallurgy the five steel Design and Research Institute and the Ministry of Metallurgy Construction Research Institute jointly developed another product, in international welding experts have music professorpersonally under the guidance of the successful solution of the problem of stainless steel or carbon steel or copper metal welding, to fill the gap, can substitute the imports.

本产品广泛用于治金、化工等行业的氧气输送管道，可有效地切断因高速气流中杂物与管壁急剧摩擦产生的火源，杜 管道燃爆事故的发生。用户可直接将本产品与输氧管道的适当部位焊接连通即可运行。

products are widely used in metallurgy, chemical industry, oxygenpipeline, which can effectively cut off the source of fire debris and wall friction dramatically due to the high-speed airflow, put an end to the pipeline explosion accident occurred. User directly to the appropriate parts of this product with oxygen pipeline welding connection to run.
