Induction Hardened Elbows

Induction hardened elbows are heat treated to a hardness of 550 to 600 Brinell or about 55 to 65 Rockwell on the inside diameter. They are both impact resistant and highly abrasion resistant.



Induction hardened wear elbows / pipe are process treated so that the inner surfaces of the wear pipe are hardened to 600 Brinell (BHN) or 55-65 Rockwell (HRC).

This special process (see below) provides progressive hardness through the wall of the pipe / elbow also yielding an outside hardness of 250 Brinnel (BHN) or 20-30 Rockwell (HRC).

This translates into longer lasting service life for convey lines on pneumatic systems, with the added benefit of simplified installation and change-out.

Available in carbon, stainless and alloys, in diameters from 2.5” to 40” NPS (73.0 – 1016.0mm), in Standard and Extra Heavy wall thicknesses, with pipe lengths of up to 40’, and bend angles all the way to 180°.
