A boiler is a common thermal energy device used to convert water heat into steam or hot water. Low and medium pressure boilers refer to boilers with working pressures between 1.0MPa and 3.8MPa. In industrial production and daily life, low and medium pressure boilers are widely used, especially in the fields of heating, gas supply, steam supply, power generation, etc. Below, the manufacturers of low and medium pressure boiler tubes will provide you with a detailed analysis.

Low and medium pressure boiler tubes are an important component of the boiler system, responsible for guiding and transmitting thermal fluids, usually water and steam. Low and medium pressure boiler tubes have the following characteristics:

1. High strength and pressure resistance. Due to the high working pressure of the boiler, low and medium pressure boiler pipes need to have sufficient strength and pressure resistance. In general, high-quality seamless steel pipes are used to ensure their mechanical and pressure resistance.

2. Good corrosion resistance. During the operation of the boiler, the boiler tubes come into contact with media such as flue gas and water vapor, making them susceptible to corrosion. Therefore, low and medium pressure boiler tubes need to have good corrosion resistance to extend their service life. Common anti-corrosion methods include internal and external coatings, galvanizing, etc.

3. Good thermal conductivity. During the process of transmitting heat energy, low and medium pressure boiler tubes need to minimize energy loss as much as possible, so they need to have good thermal conductivity. Commonly used production materials include high-quality carbon steel, alloy steel, etc. to improve heat conduction effect.

4. Good dimensional stability. Low and medium pressure boiler tubes need to withstand high pressure and temperature changes during boiler operation, so dimensional stability is an important consideration. During the production process, it is necessary to strictly control the size and shape to ensure that the boiler tubes do not deform or break under working conditions.

The production process of low and medium pressure boiler pipes mainly includes pipe procurement, processing, welding, testing, and other links. Firstly, it is necessary to choose suitable pipes, commonly used materials include 20G, 20MnG, 25MnG, etc. Then, the selected pipes are processed, such as cutting, forming, etc., to produce boiler pipes that meet the requirements. Next, the welded pipes are usually welded using welding methods such as arc welding and submerged arc welding. Afterwards, the welding parts will be inspected, such as non-destructive testing, pressure testing, etc., to ensure qualified quality.

The maintenance and upkeep of low and medium pressure boiler pipes is also very important. The manufacturer of low and medium pressure boiler tubes tells you that during use, regular cleaning and descaling should be carried out to maintain smooth passages. In addition, regularly check whether the pipeline connections are loose and whether there are water leaks, and promptly repair and replace them. Maintaining the good condition of the boiler tubes can improve the stability and service life of the boiler system, and reduce the possibility of malfunctions.

In short, low and medium pressure boiler tubes are an important component of the boiler system, and their quality directly affects the safety and stability of the boiler system. By selecting appropriate materials, strictly controlling production processes, and strengthening maintenance measures, the quality and performance of low and medium pressure boiler tubes can be ensured, thereby improving the work efficiency and reliability of the entire boiler system.
