VEL PH/PW Series
The VEL PH/PW Series provides a highly versatile solution for preheating, stress relieving, hydrogen bake-out, and post-weld heat treatment (PWHT) across a wide range of pipe diameters and flat plate applications. Engineered for precision and reliability, the system ensures uniform heat distribution, helping improve weld quality and reduce residual stresses.
Designed for demanding industrial environments, the PH/PW Series offers fast setup, accurate temperature control, and energy-efficient operation. Its flexible heating configurations make it suitable for applications in oil & gas, power generation, petrochemicals, heavy engineering, shipbuilding, and fabrication industries.
Standard Features
- Designed for continuous heating operation
