API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train and equip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking their obligations under local, state, or federal laws. For this reason, it is required that the stresses in each coupling be calculated with a? The make-up length, butt weld to butt weld, shall be documented. Other optional performance testing may be included to substantiate serviceability.
Log sheets for recording cumulative use of each riser coupling. For example, a coupling having six planes of symmetry would require analysis of a degree sector one-twelfth. The designers are encountering some difficulties in the application of this methodology to 3D finite element results.
Examination shall include 1? Use interactive graphics and maps to view and sort country-specific infant and early dhildhood mortality and growth failure data and their association with maternal.
Rosettes shall be epec. Assumptions such as load distribution, the correctness of preloading in? The manufacturer shall document the rated internal working pressure for each coupling design.

Information concerning safety and health risks and proper precautions with respect to particular materials and conditions should be obtained from the employer, the manufacturer or supplier of that material, or the material safety data sheet. Coupling design types include, but are not limited to, the types de?
For these couplings, stresses at loads other 16 the analysis loads can be calculated using the rules of linear interpolation or extrapolation. Compressive bearing load developed between box and pin members at their interface; this is accomplished by elastic deformation induced during makeup of the coupling.
The axial loading on such a degree sector can be considered to be that caused by the design tension uniformly distributed around the pipe.
The following procedure shall be used for an individual coupling design: SAF is a function of pipe size, and wall thickness. Additional traceable information is speci? An example of a pure shear stress is the average shear stress in the threads of a threaded coupling.
