To provide a two-hole pipe structure for improving reliability of a joining part and a two-hole pipe coupling allowing easy and exact mounting of the two-hole pipe straight pipe.
When the two-hole pipe straight pipe 8 is connected with a pipe coupling 10 for two-hole pipe, a brush is inserted into a space 30 of the pipe coupling 10 for two-hole pipe and adhesive is evenly applied to an inside face of a socket 22. Adhesive is evenly applied to an outside face of a tip part of a two-hole straight pipe 16. After the application state of adhesive is visually confirmed, recessed grooves 22c and 22d of the two-hole pipe straight pipe 8 and inside projections 26a and 26b of the socket 22 of the pipe coupling for two-hole pipe are exactly fitted, inserted and positioned and are guided to an I type packing 34 in a gap of partition plate receivers 24a and 24b. The two-hole straight pipe 8 is further inserted into the socket 22, the I type packing 34 is pushed into a groove 32 as shown in a Figure 4 and a pipe end of the two-hole pipe straight pipe 8 is allowed to abut on an abutting surface 22a.
