Abstract
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.
Claims5
An angle setting pipe structure connecting two pipe members at a selected axial angle, comprising:
- each pipe member having at least one annular pipe groove of a predetermined width at one end with a plurality of spaced pipe teeth formed in the pipe groove;
- and
- a mechanical coupler engageable with the pipe groove for connecting the two pipe members at a selected axial angle, wherein the mechanical coupler includes two semicircular clamping members, each clamping member having a pair of semicircular clamping flanges engageable with the pipe groove and a plurality of spaced horizontal teeth extending outward from the clamping flange, the horizontal teeth being engageable with the pipe teeth.
