ABSTRACT:
A double wall tank for the storage of liquids is disclosed, comprising a rigid inner tank having an aperture formed through a sidewall of the inner tank, and an outer sheath of synthetic resin material having an opening generally overlying the inner tank aperture and a generally annular flange member attached to the inner tank and extending over a portion of the outer sheath adjacent to and surrounding the outer sheath opening to urge that outer sheath portion toward the inner tank sidewall to form a substantially liquid impervious seal between the outer sheath and the inner tank surrounding and proximal to the inner tank aperture. A generally cylindrical passage member is attached to the inner tank adjacent the aperture and extending through the annular flange member to provide a substantially liquid-tight passage into the inner tank through the aperture and the opening in the outer end of the cylindrical passage member.
