运行锅炉及压力容器中的缺陷由产生、发展到事故发生，是要经历一个过程的。如受压元件的起槽、开裂、腐蚀、变形等都不是忽然发生的。假如能在大修中进行技术检查，即进行内、外部检验，就能及时发现缺陷，把握它的发展趋势，采取相应的措施，从而防止事故的发生。

The defects in operating boilers and pressure vessels go through a process from generation and development to accidents. For example, the grooving, cracking, corrosion and deformation of pressure parts are not sudden. If we can carry out technical inspection in overhaul, that is, internal and external inspection, we can find defects in time, grasp its development trend, and take corresponding measures, so as to prevent accidents.

锅炉管道日常注意事项

Daily precautions for boiler piping

1.各单位应成立防止压力容器和锅炉爆漏工作小组，加强专业管理、技术监督管理和专业人员培训考核，健全各级责任制。

1. Each unit shall set up a working group to prevent the explosion and leakage of pressure vessels and boilers, strengthen professional management, technical supervision and management, professional training and assessment, and improve the responsibility system at all levels.

2. 严格锅炉制造、安装和调试期间的监造和监理。

2. Strictly supervise the boiler manufacturing, installation and commissioning.

3. 防止超压超温。

3. Prevent overpressure and overtemperature.

4. 防止设备大面积腐蚀。

4. Prevent large area corrosion of equipment.
                

5. 防止炉外管爆破。

5. Prevent the tube outside the furnace from blasting.

6. 防止锅炉四管爆漏。

6. Prevent the four tubes of boiler from bursting and leaking.

7. 防止超(超超)临界锅炉高温受热面管内氧化皮大面积脱落。

7. Prevent large area of oxide scale falling off in high temperature heating surface tube of ultra supercritical boiler.

8. 奥氏体不锈钢小管的监督。

8. Supervision of austenitic stainless steel tube.

管道内窥镜可用于高温、有毒、核辐射及人眼无法直接观察到的场所的检查和观察，可在不需拆卸或破坏组装及设备停止运行的情况下实现无损检测，另外一方面工业内窥镜还可生成照相、摄像和图像处理系统，从而进行视场目标的监视、记录、贮存和图像分析，为诊断和处理提供很好的保证。

The pipeline endoscope can be used for inspection and observation in places with high temperature, toxicity, nuclear radiation and places that cannot be directly observed by human eyes. It can realize non-destructive testing without dismantling or destroying the assembly and stopping the operation of the equipment. On the other hand, the industrial endoscope can also generate a camera, camera and image processing system to monitor, record, store and analyze the field of view objects, It provides a good guarantee for diagnosis and treatment.

因此，为确保锅炉及压力管道的安全平稳运行，管道的检查工作必不可少，切实做到防患于未然。

Therefore, in order to ensure the safe and stable operation of the boiler and pressure pipeline, the inspection of the pipeline is essential, so as to prevent the trouble in advance.
