METAL PIPELINE FOR MACHINES CASTING NONFERROUS ALLOYS AT LOW PRESSURE Russian patent published in 1994 - IPC

FIELD: transportation of nonferrous metal melts. SUBSTANCE: metal pipeline has pipe corrosion resistant with respect to metal material and consists of part which is submerged in melt and part which is not submerged in melt. The latter has stepped outer surface with supporting platform and metal flanges embracing the stepped outer surface and interconnected to one another. Supporting platforms of stepped outer surface are positioned at angle: of 10-45 deg. to the axis of metal pipeline, and pipe submersible and not submersible parts are made integral. EFFECT: higher efficiency. 1 dwg
