ABSTRACT:
A blasting nozzle assembly is used for blast cleaning internal pipe surfaces. A cylindrical sleeve has a flow channel through which blasting abrasive and a carrier fluid flow in a flow direction. A web member is integrally formed with the sleeve and extends diametrically across the flow channel. The web member has a length inside the flow channel which is about 60% to 90% of the given length of the sleeve. A stem is inserted in an opening formed in the web member such that the stem extends coaxially with the sleeve. A free end of the stem protrudes from the sleeve. A deflection tip is mounted on the free end of the stem. The deflection tip radially deflects the blasting abrasive and the carrier fluid arriving from the flow channel in the given flow direction.
