Boiler tubes often work under high temperature and high pressure, and the pipe flue water will undergo oxidation and corrosion in high temperature steam. Therefore, durable steel is required to have high strength, high oxidation resistance and good structural stability. In addition to chemical composition and mechanical Performance, the roots need to be hydrostatically tested, and flaring and flattening tests are required. Steel is delivered with heat treatment. In addition, there are certain requirements for the structure, grain size and decarburization of the finished steel. High-pressure boiler tubes belong to the category of seamless steel tubes.

How to choose a good quality boiler tube?

When choosing boiler tubes, look at the following to select a suitable and good quality tube.Look at the cross-section of the tube. A good quality seamless tube will have a smooth cross-section with no bumps or irregularities.Check the density of the pipe to know the percentage of impurities in the pipe. If the pipe shows a low density, avoid it!Check the surface of the boiler tube. A good quality boiler tube has a smooth surface. If a rough and uneven surface is found, you can be sure that the quality is not acceptable.Small diameter high pressure boiler tube surface defects affect the quality, mainly the generation of scrap.

Product Introduction of boiler steel pipe

Use of boiler tubes

Boiler tubes can withstand temperatures up to 700°C and pressures up to 300 bar, and are therefore mainly used in energy equipment. They are most commonly used for steam pipes and steam boilers.
The use of boiler tubes is often determined by their additional properties. For example, acid-resistant boiler tubes are ideal for building installations that transport various chemicals because they are resistant to corrosion. On the other hand, heat-resistant boiler tubes do not deform even under the influence of high temperatures. In addition, their structural composition includes special steel alloys that minimize wear and tear.
Using thick-walled boiler tubes is worthwhile if we want to combine high strength with relatively low weight in the installation. They are also a good choice for installations where hot liquids need to be transported under pressure. Stainless steel boiler tubes are also often used. They are covered with an additional layer that protects them from corrosion, allowing them to be used in wet conditions.
