Pressure calculation formula of thick wall straight seam steel pipe
Aug 19,2024
The pressure of thick-wall steel pipe produced by steel pipe is uniform through the water pressure test. At present, the implementation standards of steel pipe at home and abroad all use the flaw detection instead of water pressure test. In engineering design, there will be corresponding requirements for the pressure of the steel pipe, and a unified formula calculation method is given in the standard to clarify the small range of theoretical pressure of the thick-walled straight seam steel pipe.
What is the pressure formula of thick wall straight seam steel pipe?
The pressure calculation formula of thick wall straight seam steel pipe is as follows:
(Yield strength x2xTx0.6)/D
Among them: the yield strength is the yield strength of the thick wall straight seam steel pipe plate, such as the yield strength of Q235B is 235MPa, and the yield strength of Q345B is 345MPa.
T is the wall thickness of the thick-walled straight seam steel pipe
D is the outer diameter of the thick-walled straight seam steel pipe
For example: 630*35mm thick wall straight seam welded steel pipe, the material is Q345B. Request: 630*35mm thick wall steel pipe pressure is how much?
Data are substituted into the formula: pressure = (2*345*35*0.6) /630=23MPa.
Usually the pressure in the thick wall straight seam steel pipe industry is called: how many kilograms of pressure can be withstand. 1MPa=10 kg.
Pressure refers to what aspect of the pressure of the thick-walled steel pipe?
The pressure calculation formula of the thick wall straight seam steel pipe mainly refers to the small pressure that the inside of the steel pipe can withstand, which is manifested as how much MPa is the pressure of the steel pipe when the internal fluid of the thick wall steel pipe exerts force on the wall of the thick wall steel pipe.
