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 [...]

Radyne’s Merlin system integrates heating and coating in one operation to increase throughput while facilitating coating operations for both S and J lay platforms. Merlin applies a precise two-coat FBE and copolymer coating delivering vastly improved cycle times and quality, vertical or horizontal application, and minimum manning levels. The benefits of the Merlin system have [...]

Induction heating of the internal surfaces of a workpiece for applications such as hardening, tempering, annealing, shrink fitting, and brazing has several unique features related to the physics of the process and the selection of process parameters, compared with heating of external surfaces. There are four main coil styles for heating internal surfaces: solenoid-type cylindrical [...]

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 [...]
