Portable PWHT Machine 5KW 10KW - Induction Heater for Welded Pipe Stress Relieving
Product Description
Designed for challenging field conditions, Canroon's PWHT induction heaters deliver reliable heat treatment where traditional ovens can't reach. The 5kW model efficiently processes 6" SCH40 pipeline girth welds, while the 10kW unit handles 16" flowlines - both critical for API-compliant stress relief in oil & gas operations. Offshore construction teams particularly benefit from the 18kg 10kW unit's IP54-rated housing and helicopter-transportable design. With rapid 10-15℃/min heating rates and dual-mode operation (preheat/PWHT), these systems are equally effective for power plant boiler repairs and pipeline maintenance, reducing treatment time by 30% versus flame methods.
