Processing Technology of Super Duplex Steel S32750

10 January 2019

Mature Super Duplex Steel S32750 welded pipe manufacturing process is (1) specific: raw material inspection, steel plate ultrasonic flaw detection, planer edge-molding, pre-welding; (2) molding in the production of straight seam welded pipe: FFX (Flexible molding), a new molding technology uses the tension effect when the coil is bent to maximize the bending moment to the edge of the steel strip, and the molding degree of the bending edge can be freely adjusted according to the strength and thickness of the steel strip to achieve the best welding conditions; (3) welding for the use of plasma arc welding (PAW) and tungsten Argon arc welding (GIAW) composite welding process: first of all, the use of plasma arc welding penetration fusion, so as to achieve single-sided welding, double-sided molding effect, after the use of Tungsten argon arc welding for filling and cover, welding using pure argon protection; (4) heat treatment after welding: heat treatment using induction furnace to the whole pipe solid solution treatment, heat treatment temperature of 1050 1120 °C, water spray cooling to 40 °C below.
