    [PDF]Table 2 Approximate Tensile Yield Strength Values, TY, for Equation (1) Certain installation methods such as horizontal directional drilling may impose additional bending stresses while the pipe is under pull-in tension. Allowable tensile load values may need to be reduced to accordingly.

  • Drill Pipe Yield Strength and Tensile Strength - Drilling

    Drill Pipe Yield Strength and Tensile Strength. If drill pipe is stretched, it will initially go through a region of elastic deformation. In this region, if the stretching force is removed, the drill pipe will return to its original dimensions. The upper limit of this elastic deformation is called the Yield Strength, which can be measured in psi.

  • API Grade E Drill Pipe

    Drill rods or pipes are thin-walled and hollow sections of steel piping. Generally produced from steel or aluminium alloys, the most commonly used heavy weight drill pipe can be made from either stainless or alloy steels. These rods are bonded together to develop a drill string. During a drilling operation, the string can be attached to the rig

    The objectives of our design efforts should be to: Keep the maximum stress at any point in the drill string less than yield strength derated by a design factor. Select components and configure assemblies to retard fatigue as much as economically practical. Provide equipment that is resistant to hydrogen sulphide if H2S is expected.
