How is the wall thickness of Q345R determined?
Thread Content
Is there a comparison table for Q345R regarding pressure and wall thickness? At an operating pressure of 3.3 Mpa, what wall thickness should be chosen for Q345R?
By the way, what is the density of Q345R steel? How to calculate weight
There are calculation formulas in GB/T150; the density of Q345R is 7.85
You can download a small hardware manual app, which can quickly calculate the weight
This is closely related to diameter and temperature...
Hehe, there is no definite answer to this question. Once the material for a pressure vessel is determined, its thickness is related to the calculated pressure, temperature, and medium, and is not solely dependent on pressure. Specific design conditions are required to calculate the wall thickness.
The reinforcement of the openings at the pipe ends also needs to be taken into consideration
Isn’t the thickness calculated? !
It was my mistake. That was too careless. Wrong again!
GB150.3 provides a formula for calculating thickness; the value obtained is the calculated thickness, which depends on factors such as design pressure, inner diameter, temperature, allowable stress of the material, and welding joint coefficient. The nominal thickness of the steel plate is obtained by calculating the thickness + corrosion allowance + negative deviation, and then rounding up
