**课程名称：** 管道和管路行业热切割技术 (Hot Tapping In Pipeline and Piping Industries) **课程概述：** 本课程深入介绍在管道、管路或设备带压（或已泄压但未清除）的情况下，通过焊接或机械连接分支接头，并进行钻孔或切割来制造开口的技术——热切割（Hot Tapping）。 **核心内容：** * **定义与应用场景：** 详细解释热切割的原理，以及其在无法停运、泄压或清洗设备/管道时的实际应用。 * **适用条件：** 强调进行热切割必须满足的关键条件，包括： * **持续运行的必要性：** 确保生产/服务流程的连续性至关重要。 * **停运的不可行性：** 系统停运会带来显著的负面影响。 * **规范化操作：** 必须严格遵循已记录的操作规程。 * **专业设备保障：** 使用能够有效保护员工安全的专用设备。 * **操作优势：** 说明热切割如何在不干扰现有工艺流程的情况下安全完成，从而避免停产带来的经济损失。 * **风险与考量：** 强调热切割的潜在危险性，并指出只有在技术上可行且相比替代方案具有明显优势时（可能包括经济效益、安全或环保风险较低等），才能选择此方法。 **重点强调：** 本课程侧重于在不中断服务的情况下，安全有效地进行管道维修和改造的技术，并严格遵守安全操作规程和使用专用设备。
Hot tapping is the technique of attaching mechanical or welded branch fitting to pipeline, piping or equipment in service while while it is under pressure or has been depressurized but has not been cleared for conventional construction method. , and creating an opening in that pipeline, piping or equipment by drilling or cutting a portion of the pipeline, piping or equipment within the attached fitting. Hot tapping is usually performed when it is not feasible, or it is impractical, to take the equipment, Pipeline or Piping out of service, or to purge or clean it by conventional methods. The decision should only be made when (1) continuity of service is essential, (2) shutdown of the system is impractical, (3) documented procedures are followed, (4) special equipment is used which will provide effective protection for employees. A hot tap connection can often be safely made without interfering with the process operation. Hot-tapping is potentially hazardous and therefore should only by undertaken when shown to be technically feasible and to offer a clear advantage over alternatives. This advantage may be economic and, in some situations, the safety and environmental risks may be less than those associated with more conventional methods.
