x80 yield strength

API 5L Pipes for Pipelines Explained - Projectmaterials

The yield strength of an API 5L pipe is specified with the number that follows the X in the material grade designation (in kilopounds per square inch i.e. KSI). So, for instance, an API 5L X52 pipe has a minimum yield strength of 52 KSI. API 5L X Grades:X52 X56 X60 X65 X70 Welded & Seamless Grades covered by this specification are A25, A, B and "X" Grades X42, X46, X52, X56, X60, X65, X70, and X80. The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.

API 5L X100 PSL2 Seamless Pipe X100 Grade Steel Pipe

API X100 steel pipes commonly used in offshore pipeline due to its high strength. The chemical composition is based on 12 types of materials which are C, Si, Mn, P, S, Cu,Ni, Cr, Mo, Nb, Ti and Al. Its yield strength is 769 MPa and tensile strength is 823 MPa. The ratio of yield to the ultimate tensile strength is 0.93.

API 5L X80 pipeline steel plate in China - Bebon Steel

API 5L X80 pipeline steel plate:X stands for pipeline steel in the API Spec 5L standard. 80 is the strength grade and its unit is kpsi. X80 represents pipeline steel with a minimum yield strength of 80 kpsi. Converted to metric units is approximately 552 MPa. In China, L stands for pipeline steel. API 5L X80 psl2, material grade x80, ISO3183 L555 steel The coiling temperature was in the temperature region from 550°C to 650°C, TS 625 MPa (TS:Tensile strength) of X80 and strength satisfied YS 555 MPa (YS:Yield strength) . API 5l X80 API X80-Grade Conductor Casing - JFE Steel CorporationX80-grade refers to a yield strength of 555 MPa. (*2) Conductor casing:A steel pipe that is placed into the ground (or seabed) at the initial stage of drilling an oil or natural gas well, as a strong external casing to protect well casings against external pressure.

Effect of Cold Bending Process and Strain-Age on

Dec 21, 2012 · Through the field cold bending and mechanical properties tests of 1219 mm × 22 mm X80 longitudinal submerged-arc welding line pipe, the effects of different bend radii consisting of 20D, 28D and 47D (D is the diameter of steel pipe) on properties of X80 linepipe were studied. the transverse yield strength and yield ratio in intrados of Mechanical Properties of High-Nb X80 Steel Weld Pipes for The mechanical properties of steel pipe have great effects on the integrality and operation safety of gas transmission pipeline. In order to reduce the cost of the steel pipe, the high-Nb X80 pipeline steels with the different alloying systems have been used in the Second West-to-East Gas Transmission Pipeline Project. Nevertheless, an investigation into the effects of chemical composition on Recommendations on X80 steel for the design of hydrogen Jun 01, 2012 · Nevertheless, with hydrogen introduced by cathodic charging in X80 steel, Zhang and al showed that the Yield Strength could decrease with hydrogen concentration. In our case, considering 300 bar of hydrogen gaseous, the solubility of hydrogen is lower, about 4.5·10 3 ppm and not sufficient to affect the Yield Strength.

Technical Report Development of X90-X100 Seamless

highest grade in terms of strength is X80, where the lower limit of yield strength is 555 MPa (unless otherwise specified, the units herein used are metric), and there have been very few cases where pipes of higher strengths are commercially used. The toughness of parent pipes and girth weld joints generally tends to decrease as the Welding on High Yield Pipe Lincoln ElectricTable 1. Summary API 5L Strength Requirements X42. X46. X52.
