Pipe bends

Changes of direction in round and flat-oval pipe, built from mitred gores. Each of these opens in the browser with default sizes that already give a verified flat pattern: change them to yours, check the drawing, add seam and flange allowances, and export.

Round

Segmented round bends, at a constant diameter or reducing and expanding, one plate per gore.

S-Offset

An S-bend of round pipe: two opposed miter bends with a straight between, from the offset or the straight you give.

Flat Oval

A segmented bend in flat-oval duct, bent the easy way or the hard way: every gore unrolled, with the mitre at each joint.

• Easy way
• Hard way

Oval to Rectangle

A segmented bend that changes from flat-oval duct to rectangular duct as it turns, bent the easy way or the hard way: every gore developed, with the mitre at each joint.

• Easy way
• Hard way

Oval to Round

A segmented bend that changes from flat-oval duct to round duct as it turns, bent the easy way or the hard way: every gore developed, with the mitre at each joint.
