Thank you, Russ.russ_watters said:Welcome to PF! This is a complicated question that requires exact details in order to be solvable.
Thank you very much, JBA.JBA said:Part of this is a units conversion issue. 863 N = 194 lbf and 1 mm ^2 = 0.00155 in ^2, i.e, the result is 125,161 lb/in^2. What is then required is the x-sectional area of the drill pipe.
At the same time, this does mean that the drill pipe's rated tensile load is equal to that result, so you must request the load rating from the drill pipe supplier to insure that the drill pipe thread joint rating is equal to or greater than that of the above calculated load bearing value plus the fact that there is surely a safety factor that is applied to the actual maximum yield stress and the thread failure load values.
Yes, JBA, I didnt apply a conversion...my bad.JBA said:You need to recalculate your x-sectional area for the pipe using the given 5.5 and 4 in dia values. My result for the area is 11.1919 in^2 for a total load limit of 1,401,229 lbs using your 125,200 psi value.
Tensile strength is the maximum amount of stress that a material can withstand before breaking or permanently deforming. It is a measure of a material's ability to resist being pulled apart by forces acting in opposite directions.
Tensile strength is typically measured in units of force per cross-sectional area, such as pounds per square inch (psi) or newtons per square meter (N/m²). It can be determined through various testing methods, such as tensile tests, where a material is subjected to a pulling force until it breaks.
The tensile strength of a material is influenced by several factors, including its chemical composition, microstructure, and processing techniques. The type of load applied, temperature, and rate of loading can also affect the tensile strength of a material.
To calculate the tensile strength in pounds, you will need to know the maximum load (in pounds) that a material can withstand before breaking and its cross-sectional area (in square inches). Then, simply divide the maximum load by the cross-sectional area to get the tensile strength in pounds per square inch (psi).
Knowing the tensile strength of a material is crucial in engineering and construction industries. It helps determine the suitability of a material for a specific application and allows engineers to design structures and components that can withstand the expected loads. It also helps in quality control and ensuring the safety and reliability of products.
