蒸汽节能系统操作中预防压力管道安全事故的技术措施有哪些？

预防压力管道安全事故的技术措施。

在压力管道中，蒸汽管道的内部介质大多是沸腾的热水。由于使用寿命长，管壁变薄，管道的压力达到管道的承载能力，导致管道爆炸事故。蒸汽管道每隔3-5年后，建议进行试管承压试验。

蒸汽管道的腐蚀容易发生在管道的弯曲和弯曲部分。流线型管段有蒸汽流入和流向变化的部分。埋管外下表面容易腐蚀。在管道强度设计中，应根据管道介质的特性、流速、工作压力、管道材料、使用寿命等计算介质对管道的腐蚀率，并在此基础上选择适当的腐蚀裕度。壁厚的腐蚀裕度一般在1.5mm-6mm范围内。

管道在控制或保持热量的情况下应进行保温，以减少由于阳光或外界温度过高引起的管道蒸发。设备应保温；在操作人员可能接触到的范围内，应作为防烫措施进行保温。

管道保温常用的保温材料有毛毡、石棉、玻璃棉、石棉水泥、岩棉和各种保温泡沫塑料。材料的导热系数越小。容量（单位体积质量）越大。吸水性越低，保温性能越好。此外，材料稳定、不可燃、耐腐蚀、一定强度等有利于材料的保温。

管道防腐涂层。防止管道腐蚀应从两个方面入手：一是合理选择管道，即根据内部介质的性质选择具有耐腐蚀性的管道材料；二是采取涂层防腐、衬里防腐、电化学防腐、缓蚀剂等合理的防腐措施。其中，涂层防腐应用广泛，涂层防腐应用广泛。
