An angle setting pipe structure and fabricating method that using a mechanical coupler for connecting two pipe members at a selected axial angle. The pipe members are being made by roll forming at one end to form an annular pipe groove which has a plurality of spaced pipe teeth. The mechanical coupler has clamping flanges to engage with the pipe groove and a plurality of horizontal spaced teeth extending outward from the clamping flanges for engaging with the pipe teeth. The pipe members thus may be securely connected at a selected angle without the risk of angle skewing.
