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.
Daily precautions for boiler piping
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. Strictly supervise the boiler manufacturing, installation and commissioning.
3. Prevent overpressure and overtemperature.
4. Prevent large area corrosion of equipment.
5. Prevent the tube outside the furnace from blasting.
6. Prevent the four tubes of boiler from bursting and leaking.
7. Prevent large area of oxide scale falling off in high temperature heating surface tube of ultra supercritical boiler.
8. Supervision of austenitic stainless steel tube.
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.
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.
