How long do boiler tubes last?

The life of a boiler tube is usually determined by a variety of factors, such as material quality, design and manufacturing quality, use conditions, maintenance, etc.

Service life of a boiler tube:

Generally speaking, the average life of a boiler tube is between 10-30 years, and the specific life depends on the degree of influence of the above factors. If the use conditions of the boiler tube are more demanding, or the maintenance is not in place, the life may be shorter. At the same time, the boiler tube will be affected by factors such as high temperature, high pressure and corrosion during use, which will also shorten its life. Therefore, the correct use and maintenance of the boiler tube can extend its life.

Factors affecting life:

Equipment quality: The manufacturing quality of steam boiler tubes is directly related to their service life. High-quality equipment materials, exquisite craftsmanship and strict quality control can ensure the long-term and stable operation of the boiler.

Operating environment: The operating environment in which the boiler tube is located will also affect its service life. For example, the quality of water, the amount of smoke, temperature fluctuations and other factors will affect the degree of corrosion and wear of the boiler.

Maintenance: Regular maintenance is the key to ensure the long-term operation of the boiler tube. Including cleaning, descaling, inspection, tightening and other work, which can timely discover and solve problems and extend the service life of the boiler.

Operation specifications: The skill level and operation specification of the operator will also affect the service life of the boiler tube. Reasonable operation can reduce the load fluctuation of the boiler and reduce the wear rate.

Methods to extend the service life:

In order to extend the service life of industrial steam boiler tubes, you can start from the following aspects:

Choose high-quality equipment: When purchasing boiler tubes, you should choose qualified and reputable ones to ensure the quality of the equipment.
Optimize the operating environment: Reduce the corrosion and wear of boiler tubes by improving water quality, reducing smoke emissions, stabilizing temperature and other measures.
Strengthen maintenance: Establish a complete maintenance system, regularly inspect, clean, descale and other work on the boiler to ensure that the equipment is in good condition.
Improve operating skills: Strengthen the skill training of operators, improve the degree of operation specifications, and reduce equipment damage caused by misoperation.

Scrap conditions:

Although there is no clear service life for industrial steam boiler tubes, their scrapping is usually based on the following two conditions: one is that the thermal efficiency is lower than the actual specified value; the other is that safety cannot be guaranteed. When the boiler meets any of these two conditions, it needs to be overhauled or scrapped.
