The invention relates to N80-grade welding petroleum casing steel and a manufacture method thereof. The welding petroleum casing steel comprises the following components in percentages by weight:0.20-0.30 percent of C, 0.1-0.5percent of Si, 1.2-1.6 percent of Mn, 0.04-0.06 percent of Nb, 0.05-0.10 percent of V, 0.01-0.02 percent of Ti, 0.03-0.05 percent of Al, less than 0.02 percent of P Development of API X70 Grade Hot Rolled (HR) Coils for May 01, 2016 · In this paper, efforts made at BSL, SAIL towards developmental of API X70 grade HR coils intended for SW pipes, have been presented. Two trial heats with Nb-Cr-V and Nb-Cr-V-Mo based chemistry aiming (a) ferrite-pearlite and (b) ferrite-pearlite-bainite microstructures respectively were made and cast into 1400 x 210 mm slabs. These trial slabs were processed under suitably designed

Evaluation of modern, X70 and X80 line pipe steels:Final

Apr 01, 1992 · Nine sections of advanced high strength line pipes, Grades X70 and X80 have been evaluated during this study. Six of those pipes were Grade X70 and three were Grade X80. Four of the X70 pipes were fabricated from microalloyed steels that were controlled rolled; the other two X70 How to weld Duplex Stainless Steel.ppt [Read-Only]Duplex Stainless Steel Tack welding To prevent shrinkage during welding precise tacking is important. For material up to 6mm tack length should be 10-15mm. Above 6mm tack length should be 20-25mm. Distance between tacks is 150-200mm. In single sided welding, the entire tack must be ground away before welding.

Mechanical Response and Performance Relationship of X70

With the development of the natural gas industry, high flux natural gas pipelines will cause local deformation because of pressurization, which has an important effect in the service safety of pipeline materials. In this paper, the X70 pipeline steel with weld zone was studied, and the tensile test was used to simulate the uniaxial tensile stress.
