FIELD: transport, distribution.SUBSTANCE: invention relates to discharge pipe for resilient tank with rigid body making the discharge channel and tube to be fitted between two walls of resilient tank and tightly secured thereto. Said tube features smooth outer surface with two opposed flat shields extending outward from its axial plane. Tube outer surface and that of said flat shields make the sealing surface. Said outer surface has convex contour in direction parallel with tube axis. Mid area is located at tube convex outer surface whereat distance to tube axis is maximum to separate end areas. Distance to tube axis at end areas decreases toward their ends opposite mid areas.EFFECT: better seal, ruled out outflow of fused plastic.6 cl, 10 dwg |
