Pipe stress problem
Thread Content
Generally speaking, compared with thick pipes with the same pressure, the wall thickness of thin pipes does not need to be too thick. Is this view correct? It is said that the total pressure endured by thin pipes is small, but when considering the wall thickness and material, shouldn't the pressure be considered? That is the force per unit area. Please give advice!
Apply the pressure vessel wall thickness calculation formula. The wall thickness is proportional to the diameter.
This depends on the pressure level. The higher the pressure, the thicker the wall will naturally be. If the pressure level is the same, small pipes are generally thinner. Many relevant manuals have pipeline wall thickness grade tables, which can be reflected more intuitively.
GB/T20801.3-2006 is proportional to the outer diameter of the steel pipe
