Inductoheat - An Inductotherm Group Company

Stress relieving of steel tube/pipe ends is typically done prior to machining of the thread.

In stress relieving of oil country tubular-steel goods, the typical temperature-uniformity requirement is ±50 ?F at target temperature levels of 700-1250 ?F depending upon the particular steel grade and application specifics. The uniformity achieved in most induction systems is ±80 ?F, however, when heating a variety of pipe sizes, in some instances heat non-uniformity may [...]

The stress-relief operation is an important step in the manufacture of a quality connection. Improper heat treatment could result in several undesirable phenomena from total joint failure to a type of bi-metallic corrosion known as “ring-worm corrosion” that occurs in improperly stress relieved or normalized pipes. This corrosion takes the form of a ring around [...]
