DOUBLE WALL TUBE SECTION FOR THE MANUFACTURE OF FIREPLACES.

摘要

THE INVENTION REFERS TO A TUBULAR SECTION OF A DOUBLE-WALL CHIMNEY PIPE FOR A CHIMNEY STRUCTURE, WITH A CYLINDRICAL INTERIOR SPACE, CHARACTERIZED BY AN EXTREME EXTREME, WITH A CYLINDRICAL OUTER PIPE, THAT SHOWS A EXTREME WILLING BETWEEN THE INNER TUBE AND THE OUTER TUBE. A TUBULAR SECTION, FROM WHICH THE STAINLESS FIREPLACE TUBE CAN BE FORMED BY MOUNTING TO THE CONDENSATION AND GAS FOR THE SANITATION OF THE FIREPLACES, IS CHARACTERIZED BECAUSE BOTH THE TUBE (2) INTERIOR AS THE TUBE (3) EXTERNAL AN EXTREME (6 OR 9) THAT IS EXTREMELY EXTREMELY AND AN EXTREME (7 OR 10) THAT IS REDUCED ALSO CONICALLY, EXPANDED, SO THAT THE EXTREME (6, 7, 9, 10) CONICALS SHOW THE SAME ANGLE OF CONDITION AND THE EXTREME (7, 10) OF CONICAL REDUCTION SHOW IN ALL ITS LENGTH A DIAMETER GREATER THAN THE PARTS (5, 8) CYLINDERS OF THE TUBE (2) INTERIOR OR OF THE TUBE (3) EXTERIOR, WHICH ARE PROVIDED IN THE AREA OF EACH SIDE FRONT OF THE TUBULAR SECTION WITH AN EXTREME (7 OR 10) THAT IS REDUCED CONICATELY, AS WELL AS AN EXTREME (6 OR 9) THAT IS CONICALLY EXTENDED AND SO THAT A SPACE (11) CANCELED CONFIGURED BETWEEN THE END (7) THAT IS REDUCED CONICAL WAY OF THE TUBE (2) INSIDE AND THE END (9) EXPANDING WAY CONICAL OF THE TUBE (3) EXTERIOR EST FREE OF INSULATION.
