HEMCO manufactures double wall casings with joints made through a special rolling-forging process using an extremely high strength, wear-resistant steel alloy. In order to provide adequate structural capacity against torsion and crushing (especially when the double wall casings are used in conjunction with casing oscillators), steel bars fabricated in the shape of spirals are painstaking welded to the inner side of the outer casing tube (for 620mm casings, the steel bars are welded to the outer side of the inner casing tube).
