Spray nozzle i.e. high pressure nozzle for descaling steel products, has outlet clamping curved surface, and another surface abutting against boundary of outlet in radial direction at specific angle to central longitudinal axis
The nozzle has a mouthpiece (12) comprising an outlet (30) and a discharge chamber (34) tapering to the outlet. The outlet clamps a curved surface, and a surface (32) surrounding a boundary (38) of the outlet abut against the boundary of the outlet at each point of the boundary in a radial direction at an angle between 65 and 95 degrees to a central longitudinal axis. The boundary of the outlet is formed in sections by using chamfers, where the mouthpiece is formed from hard metal. The mouthpiece is sealed against a sealing housing by a metal joint.
