API Standard 1104 (19th edition), section 188.8.131.52 is silent with respect to how one should treat dual stencilled pipe that crosses two of the three material groups cited in section 184.108.40.206 as in the case of API 5L Grade X42/X52 pipe. Fatigue Crack Growth at Electrical Resistance Welding Seam Mar 28, 2017 · In the current research work, fatigue crack growth was investigated in NPS 20, API 5L X-70 grade, electrical resistance welding (ERW) straight-seam steel line pipes in the base metal and at the weld seam for various orientations. Measurements of the Thermophysical Properties of the API The thermophysical properties of API 5L X80 steel were experimentally measured, in order to use these in computational models to determine the temperature field in welded joints. In this work, values of thermal expansion coefficient, specific heat, thermal diffusivity and thermal conductivity were experimentally obtained as a function of temperature.
