Assessment of girth welds involving plastic strain during installation. Assessment procedure. One assessment method which is commonly applied to define flaw acceptance criteria for girth welds employed in reeled pipeline is an extension of Burst Pressure Prediction of Pipes With Internal Corrosion Mar 17, 2020 · The mechanical response of carbon steel API X42, X52, and X70 pipe grades are empirically estimated and implemented in a finite element model. The geometry of an internal corrosion defect is defined through its depth, width, and length, and a parametric study is undertaken to investigate the influence of the corrosion defect parameters to the
This thesis deals with assessment of defective API 5L X65 steel pipes which are widely used in product transportation in oil and gas industry. The objective of the thesis is to determine the burst pressure of defective API X65 steel pipes under the effect of gouge length for different pipe diameter. The thesis describes the finite element analysis techniques to predict the true Development of stress-modified fracture strain for ductile Mar 16, 2007 · The present paper proposes ductile failure criteria in terms of true fracture strain (the equivalent strain to fracture) as a function of the stress triaxiality (defined by the ratio of the hydrostatic stress to the equivalent stress) for the API X65 steel. To determine the stress-modified fracture strain, smooth and notched tensile bars with four different notch radii are
The carbon steel API 5L grade X65 sample section 96 cm long, 16 cm of outside diameter and 1 cm of wall thickness was supplied by the Casabe field. The composition of abrasive slurry was defined from historical registers of the Casabe field and brine concentration was determined from the chlorides content in produced water (approximately 6000 ppm). Engineering Failure Analysis Vol 104, Pages 1-1242 Assessment of API X65 steel pipe puffiness by a strain based design (SBD) approach under bi-axial loading Taieb Kelil, Mouna Amara, Mohammed Hadj Meliani, Bassam Gamal Nasser Muthanna, G. Pluvinage
Dec 01, 2018 · It should be clarified that the measured true stress versus true strain curves for the API X65 steel pipe (i.e., American Petroleum Institute specifies a minimum yield strength of 65,000 psi or 448 MPa for X65 steel pipes) of Zheng et al. (2012) and the HDPE PE80 pipe (high-density polyethylene pipes with a minimum required long-term strength of 8.0 MPa) of Journal Archive - Articlesmodeling the hot deformation flow curves of api x65 pipeline steel using the power law equation [abstract-en] prediction of hot deformation behaviour of a ph stainless steel at high strain rates [abstract-en] new method for life assessment of 1%cr-0.5% mo low alloy steel on the base of grain boundary creep cavitations
In addition, ULCF tests are very challenging and there are no specific standards available in literature providing guidance. In this work, the performances of the X52, X60, and X65 API steel grades under monotonic, LCF, and ULCF loading conditions are investigated by means of an experimental program. Numerical Modeling and Comparison of Defects Present in a Feb 16, 2021 · This paper presents an optimized numerical model based on finite elements to assess the stress concentration factor around constrained and unconstrained dents in an API X52 steel pipe subjected to
sequence to apply to all areas of pipe strain-based design. This situation would indicate that assessment (ECA) become fewer when the plastic strain exceeds 0.005 (0.5%) and fewer still API American Petroleum Institute APIA Australian Pipeline Industry Association ASTM American Society for Testing of Materials Structural Integrity Evaluation of API 5L X65 Pipe The effects of prestrain on the mechanical properties of API 5L X65 pipe were diversely investigated through the tensile test, crack tip opening displacement test and Charpy impact test. Axial tensile pre-strain of 1.5, 5 and 10% was applied to plate-type tensile specimens cut from the pipe body prior to mechanical testing.
