Abstract: PTA (refined terephthalic acid) is one of the important organic raw materials in chemical fiber, light industry, electronics and other industries. This paper aims at the working condition characteristics of PTA plant, the design reference standard, material selection scheme, development ideas and technical characteristics of large-diameter titanium alloy globe valve are introduced, and the design and calculation of its key components are analyzed with a typical specification product, which can guide the domestic development of the valve and related technology research..

Keywords: titanium alloy; large diameter; global valve; calculation; PTA

近年来,得益于石化行业生产技术的不断进步及PTA产业链的发展需求,新建及扩建的PTA装置不断增加,PTA装置规模日趋大型化[1]。(剩余6006字)
