石油化工与炼化Petrochemical & Refining
这一领域的工况特征是高温、高压与强腐蚀并存，且一次非计划停机的代价很高。内件的强度、直线度与焊接质量，以及滤芯的抗堵与再生能力，是选型时优先考虑的因素。High temperature, high pressure and aggressive corrosion coexist here, and the cost of an unplanned shutdown is high. Internal strength, straightness and weld quality — along with element fouling resistance and regeneration — drive specification.
- 反应器内件：扇形筒、中心管/内筛、支撑格栅Reactor internals: scallop tubes, center pipes / inner screens, support grids
- 催化剂与贵金属回收：拦截细颗粒，减少介质流失Catalyst and precious metal recovery: retaining fines, reducing media loss
- 工艺介质过滤：石脑油、蜡油、油浆、胺液等Process stream filtration: naphtha, gas oil, slurry oil, amine solutions
- 开车阶段临时过滤：T 型与锥型过滤器拦截焊渣管垢Commissioning filtration: T-type and conical filters trap weld slag and scale
