Pipe End Heating

The precessing of pipe ends includes drilling, threading, welding and other types of mechanical deformation which may require heat treatment to harden the metal or to eliminate residual stresses. In addition, tube ends are often heated and then upset (formed) to increase or decrease the diameter or wall thickness to allow pipes to be joined end-to-end.

Pillar Induction pipe-end heating systems are designed for a variety of these applications including:

• Preheat for welding & swaging
• Friction weld and swage
• Stress Relieving
• Tempering
• Austenitizing
• Annealing
• Normalizing
• Coating curing and removal
• Upsetting

Features Include:
• Single or multi-turn solenoid coils
• SCR or IGBT power supplies available from 200Hz to 3000Hz depending on the process and pipe size.
• Infrared temperature monitoring systems
• Advanced temperature process monitoring and chart recording
• Process analysis using 2D and 3D modeling
• Infrared camera analysis in the field or in our lab
• Pipe or coil positioning equipment as required
• Cooling systems
