Based on the above information, let us consider API 5L X70 pipeline of 32-inch NPS, that has a 0.500-inch wall thickness. Using a temperature de-rating factor of 1.00, we calculate the MOP of this pipeline from following:P= {2x t x SMYS x1x factor (class1) x 1} / D (ASME B 31.8 Section, 841.11) Substituting the values: Advanced submerged arc welding processes for Arctic The influence of titanium powder additions on API 5L-X70 steel was studied in Beidokhti et al. 47 It was found that the best combination of microstructure and impact properties was obtained in the range of 0.02%0.05% Ti in the weld metal.

Effect of Temperature-Force Factors and Concentrator Shape

The influence of the notch shape on the impact fracture of 17Mn1Si steel is investigated at different temperatures with the focus placed on the low-temperature behavior. An approach towards fracture characterization has been suggested based on the description of elastic-plastic deformation of impact loaded specimens on the stage of crack initiation and growth at ambient and lower temperatures. Instrumented impact testing and its application to the An instrumented impact test (IIT) machine was constructed and calibrated using static and dynamic loading. The theory and fundamentals of IIT have been reviewed. Tests were performed to assess the proposed ASTM IIT validity criteria. The requirements that the fracture time be greater than 3 times the period of specimen oscillations and 1.1 times the electronic response time appear to be

However, a minimum charpy value of 27J has been recommended for yield strength around 200 to 275 Mpa. For x42 and x46 grade steels, the minimum toughness value requirement should be around 28 to 35 J for higher operating pressure.

The EPRG Recommendations for Crack Arrest Toughness for

The toughness was measured by the full-size equivalent, upper shelf Charpy V- notch impact energy. The EPRG then revised and re-published the recommendations in 1995 [2]. The first edition was applicable to line pipe steel grades up to API 5L X70. The second edition was extended to include recommendations for API 5L X80. Validation of Charpy Impact Energy Transition Curve Shape An idealised Charpy transition curve is provided in Annex J of BS 7910:1999 which enables the 27J transition temperature (T27J) to be estimated from Charpy tests conducted at a single temperature. The validity of this transition curve is examined using data representing a range of ferritic steel grades (including parent plate, weld metal and heat affected zone).
