Since the A420 WPL3 Carbon Steel Buttweld Reducer is produced using an ASTM standard, it needs to undergo certain tests. Some of the tests and inspections carried out on the fittings include – visual examination, chemical analysis, hydrostatic test(when required), dimensional inspection, tensile test, impact test, and radiographic test(RT).
The specification calls for the ASTM A420 WPL3 Fittings to be furnished with heat treatments such as normalizing, normalizing and tempering, annealing, or quenching and tempering. To prevent corrosion, the fittings need to be welded before undergoing austenitizing heat treatment. Once they have been formed, the ASTM A420 WPL3 Carbon Steel Pipe Fittings need to be cool below their lower critical temperature; following which the fittings will be subjected to heat treatments.
A WPL3 LTCS Tee can be used in low-temperature applications and is welded easily. High carbon content in an alloy causes intergranular corrosion. However, because the carbon content in this alloy is low – it has minimal risk of the welded area getting corroded. The fittings work well in severely corrosive environments.
A carbon steel ASME SA 420 WPL3 Elbow has a tensile strength ranging between 60 Mpa – 95 Mpa.
