COMPOSITE STEEL PIPE USING STAINLESS STEEL AND CONCRETE, FORM AND METHOD FOR MANUFACTURING THE SAME, CAPABLE OF ENHANCING DURABILITY AND PREVENTING CORROSION BY PLACING CONCRETE TO ENTIRE OUTER SURFACE OF A STAINLESS COMPOSITE STEEL PIPE

摘要

PURPOSE: A composite steel pipe using stainless steel and concrete, form and method for manufacturing the same are provided to place concrete without moving the composite steel pipe under the ground since the form is divided to four sections and is assembled/disassembled successively. ;CONSTITUTION: A composite steel pipe using stainless steel and concrete consists of a stainless steel pipe(10) and a concrete cover(20). The cylindrical body(11) of the stainless steel pipe comprises smooth inner and outer surfaces. Flanges(12) are formed perpendicularly to the length of the body along both ends of the body. The flange of the body is water-tightly fastened with another flange by a bolt. A plurality of stainless steel pipes are connected by fastening of flanges. The concrete cover covers the outer surfaces of the connected stainless steel pipes with a given thickness.;COPYRIGHT KIPO 2011
