某石化厂30万吨/年润滑油高压加氢装置使用的小直径高压加氢换热器具有直径小、器壁厚的特点,筒体成形时的变形量较大,换热器管程和壳程的密封元件是Incoloy 825材质的Ω密封环,材料特殊,加工精度要求高、制作难度大,通过多方面论证,确定利用钢板分两瓣热冲压成形的的工艺方案制作筒体,不仅能够降低设备的预算、而且节约了大量的制造成本。
A petrochemical plant 300,000 tons / year high-pressure hydrogenation of lubricating oil used in small-diameter high-pressure hydrogenation heat exchanger has the characteristics of small diameter, wall thickness, the deformation of the cylinder forming a larger heat exchanger tube and The shell sealing element is the Incoloy 825 Ω seal ring, the material is special, the processing precision is high, and the production is difficult. Through various demonstration, it is determined that the steel plate can be made into a cylinder by a two-piece hot stamping process, Reduce equipment budget, and save a lot of manufacturing costs.
