Our 3A Sanitary approved, long radius elbows are available in sizes from 1" to 6" diameters with centerline radii ranging from 12" to 48". All elbows have standard 12" tangents and are available in 45 and 90 degree. Any end connection and tangent length can be configured at our facility per customer requirements. All elbows come standard in 316L stainless steel material. Other centerline radii, finishes, and degrees are available for your application.

Wrinkles and Humps

N/A
Surfaces shall be generally free of wrinkles and humps: however, for pipe or tubing with large ratio of outside Diameter (O.D.) to wall thickness, there’s a tendency for small wrinkles to develop on the inside of the bend. The depth of this wrinkling as determined from crest to trough shall not exceed the following:

Up to 2.375” O.D. : 0.031”
2.376” to 3.5” O.D. : 0.047”
3.501” to 4.5” O.D. : 0.062”
4.501” O.D. & Up : 0.094”

The ratio of distance between crest to depth shall be greater than or equal to 12.
