For domestic projects, is the wall thickness of the fittings generally the same as that of the pipes?

For domestic projects, when designing, the wall thickness of the fittings is usually the same as that of the pipes – is that generally acceptable? The wall thickness of fittings can be thicker than that of pipes, but it cannot be thinner, right?
Generally, they are matched with each other; for example, pipes and fittings use the same schedule number such as SCH, or if purchased based on wall thickness, the same wall thickness is used or the pipe has a slightly thinner wall thickness. The overall principle is mutual matching. Fittings are a bit thicker than pipes because the fittings tend to wear out more severely than straight pipes, so they are made thicker. But for ordinary pipes, these are not problems, as the wall thickness we choose is much greater than the calculated wall thickness.
Everything needs to be calculated, but there are few people who know how to do it, and costs need to be saved as well.
The wall thickness of both pipes and fittings must be calculated, and the calculated wall thickness for fittings, especially elbows, will be thicker than that of the pipes. For normal medium-temperature and medium-pressure pipelines, the wall thickness we choose is much greater than the calculated wall thickness; therefore, it is no problem to use the same wall thickness for fittings and pipelines. But under high temperature and pressure conditions, it’s different; fittings, especially elbows, are much thicker than the pipes themselves.
Calculate using the formula. . . Under the same pressure, the elbow is thicker. . The inner side of the elbow must withstand a higher force than that of a straight pipe, while the outer side experiences a lower force. .
