Seamless elbow at what temperature is good

Seamless elbows are commonly used in piping systems to change the direction of pipes. It has the advantages of simple structure, easy operation, good sealing and so on, and is widely used in petroleum, chemical, electric power, aerospace and other fields. In the use of seamless elbow, temperature is an important parameter, which affects the performance of the elbow.

First of all, the material of the seamless elbow is the key to selection. Under normal circumstances, the commonly used materials are carbon steel, stainless steel, alloy steel, etc. Different materials have different high temperature resistance, so when selecting seamless elbows, it is necessary to choose the appropriate material according to the specific working temperature. Carbon steel has good mechanical properties at room temperature, but it is easy to soften and deform at high temperature. Stainless steel has good corrosion resistance, suitable for general high temperature environment; Alloy steel has better high temperature resistance, suitable for high temperature, high pressure working conditions.

Secondly, when using a seamless elbow, it is necessary to consider its use temperature range. Different materials of seamless elbow adaptability to temperature is different, in general, the use of carbon steel temperature range of -29℃~425℃, the use of stainless steel temperature range of -196℃~816℃, and the use of alloy steel temperature range is wider, can reach -196℃~1200℃. Therefore, when choosing a happy seamless elbow, it is necessary to determine the appropriate material and model according to the actual working temperature.

In addition, in addition to considering the material and the temperature range of use, it is also necessary to consider the pressure resistance of seamless elbows at high temperatures. In the
