PURPOSE: A structure and method of pipe connection for water piping is provided that the stainless steel pipe is applied. In that way the inside damage or the corrosion of the pipe is prevented. The manufacture cost is reduced. CONSTITUTION: A structure of pipe connection for water piping comprises an expanded socket(10), an inner ring(15), and pressing rings(32,34). The expanded socket is connected to the end part of a straight pipe(S) or a bent pipe(B), formed into the stainless steel pipe. The inner ring is connected to the end part of the expanded socket, is formed into the carbon steel or the cast iron material. The pressing ring pressurizes a packing(26) in the outside of the inner ring and is installed airtightly.
