Busada was one of the first plastics tubing and pipe manufactures to offer customers long radius sweeps, and we have done it for over 65 years. Before we had our advanced heaters, we would use hot oil, salt, glycol, vermiculite and other ways to heat the tube. In the 50’s we would bend a sweep “by eye.” Here is what we have been doing lately . . . much more than just the average 90° bend.
Do you need an offset bend?
If you do, simply provide us a triangle. Tell us the vertical offset that you need, and the horizontal distance between your connection points. You can
specify the tangent (the straight connection points) and we can provide you the offset based on longest possible radius.
Finally, this pic shows how offset bends can simplify installation and eliminate couplings.
