API 5L Grade X80 PSL2 Seamless Pipes | X80 Steel Line Pipe x80 yield strength Submerged arc welding
Api 5l X80 Pipes made via welding can be processed to such a degree that the longitudinal weld seam made on the body is reduced. This procedure is practised by several manufacturers to avail good quality welded pipes at an affordable cost. API 5L Pipe Specification (Updated on 2020) - Octal SteelFor intermediate grades greater than Grade L320 or X46 and lower than Grade L555 or X80, the tensile strength shall be 760 MPa (110 200 psi).For intermediate grades higher than Grade L555 or X80, the maximum permissible tensile strength shall be obtained by interpolation. For SI units, the calculated value shall be rounded to the nearest 5 MPa.

Consumables for Welding High Strength Pipeline Steel
solid wire in submerged arc welding. This has been successfully employed in pipe mills and offers some interesting metallurgical benefits. For weld metals up to around 600 MPa yield strength, which includes most seam welds in X80 pipe steels, the preferred microstructure to optimize strength and toughness is acicular ferrite. Double Jointing of High Strength Pipelines - Welding in the WorldFor X80 steels, submerged arc welding with tubular wires and with twin arcs can allow high productivity to be maintained while limiting the heat input and dilution, and satisfactory results produced by this route are presented. Special boron-containing wires can also be used where high dilution cannot be avoided.

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 x80 yield strength Submerged arc welding
Fracture toughness of the materials in welded joint of X80 x80 yield strength Submerged arc welding
Generally, elongation and plasticity of the metals decrease with the ratio of yield to ultimate strength rising . But the X80 steel has relatively high elongation at fracture, though its yield to ultimate strength ratio is very high. This exhibits that the X80 steel has desirable mechanical properties. The yield strength and the ultimate strength of the WM are both higher than the BMs, which exhibits that an overmatched welded joint is developed. Hydrostatic burst test 0F X80 grade steel pipe - ScienceDirectTo evaluate the future application of X80 steel pipe in high-pressure oil and gas pipelines in China, hydrostatic burst tests were performed. The deformation and yield strength of longitudinal submerged arc-welding steel pipe 1016 18.4 mm under five applied pressure levels were measured. When the hoop stress is lower than 1.1SMYS, the pipe normally deforms elastically and uniformly with the maximum strain less than 0.3%.
