API5L X65 PSL2 + PWHT - Metal and Metallurgy engineering Jan 19, 2006 · The maximum specified PWHT temperature for TMCP plate is 1200 deg F. If the mill is proposing to substitute the TMCP plate to avoid PWHT, this is not a correct assumption for your application. The PWHT will need to be performed for plate thickness in excess of 3/4" (19mm) in accordance with ASME B31.3 for S-No 1 material (API 5L X65).
Analysis of internal corrosion in subsea oil pipeline Apr 01, 2014 · The main alloying elements specified by API 5L X52 are C, Mn, Nb and V with impurities of P and S. Referring to Table 1, it can be seen that the pipeline composition fulfills that specified by API 5L X52. Of note is that elements such as Nb and V are normally added to steels as grain refiners during thermomechanical control process (TMCP).
Oct 13, 2009 · For all Charpy impact tests, the test temperature criteria in (a) or (b) below shall be observed. (a) Charpy impact tests shall be conducted at a temperature no higher than the lower of the following:(1) 20°C (70°F) (2) the lowest metal temperature at which a piping component or weld will be subjected to a stress greater than 41 MPa
Impact Characterization of Line Pipe Steels by Means of In the work presented here, we characterized the impact properties of four line pipe steels ranging from a 50-year-old service-exposed steel (X52) to modern high-toughness and high-ductility steels (X65, X70, X100). X65 and X70 exhibit a high ductility-to-strength ratio and ductile specimens hardly fracture, whereas X100 has a
