Hollows

Forged hollows are widely used in high temperature/pressure and other harsh condition

Forged hollows are widely used in high temperature/pressure and other harsh conditions, such as hydrogenation reactors, nuclear reactor pressure vessels, evaporators, submarine oil and gas pipelines, etc., thanks to their durability, anti-corrosion features, high strength and long service life.

Hollows highlights

Faster delivery:

The process can ensure one-time forming with high quality surfaces and uniform cylinder thickness. At the same time, it can use direct quenched-tempered heat treatment, and does not require rough machining processes, all of which helps reduce machining time and improves efficiency.

Better performance:

Compared with large-scale forged hollows manufactured using free-forging, casting, plate rolling, etc., the compact structure, finer grains, circumferentially arrayed fibers and rational streamline distribution of rolled parts, ensures greater mechanical strength, higher impact toughness and higher fatigue resistance.
