Collapse pressure is calculated using either the Murphy and Langner equation, the Timoshenko and Gere equation, or the API equation. Buckle propagation pressure is calculated using either the DNV equation, the BSI equation, or the API equation.

WebbThe primary formula used for predicting horizontal defl ection for fl ex-ible pipe is the Modifi ed Iowa Formula. It establishes the relationship between the load on the pipe (D lK sW cr 3), the pipe support (EI) and the soil support (0.061E′r3) and demonstrates the importance of the soil interac-tion with the pipe. The equation is: Δx ... Webb2 feb. 2024 · Dawson and Paslay developed the following formula for critical buckling force in drill pipe.. I is axial moment of inertia. W is buoyed weight per unit length.. 0 is borehole inclination.. r is radial clearance between the pipe tool joint and the borehole wall.. If the compressive load reaches the Fcr, then sinusoidal buckling occurs.
Webb4 nov. 2024 · The tensile force acting at the cut off point in the Heavy Weight Drill Pipe (HWDP) is denoted by FT. Now for the system to be in static equilibrium, the forces acting upward must be equal to the forces acting downward, or Ft + WOB + F2 = W1 + W2 + F1 Where W 1 = L H W H W 2 = L C W C F 1 = P 1 (A 2 -A 1) F 2 = P 2 A 2
