The Next Generation of HSD-Powered PWHT Solutions
PWHTTech India introduces the PWHT FireWave System, an innovative High-Speed Diesel (HSD)-powered heat treatment solution designed to streamline and enhance the Post Weld Heat Treatment (PWHT) process. Engineered for pressure vessels, storage tanks, offshore structures, and heavy industrial fabrications, the FireWave System provides consistent, high-efficiency heating with optimized fuel consumption, reducing operational costs while meeting stringent industrial standards.


















PWHT processes often run for 30 to 40 hours, requiring reliable, controlled, and uniform heat distribution. The FireWave System overcomes industry challenges related to power consumption, heat loss, and environmental constraints by using high-performance HSD burners, advanced thermal insulation, and intelligent temperature control systems.
The system supports two primary PWHT methods, making it versatile and adaptable for various industrial applications:
1️⃣ Internal Firing Method – Heat is applied through nozzles, manholes, or designed openings, with external insulation reducing heat loss.
2️⃣ Furnace-Based Method – A temporary or permanent furnace is enclosed with high-temperature ceramic insulation, allowing uniform heating from external HSD burners.
Both methods are widely used across global industries and approved under international standards such as ASME, API, and other industrial regulations, ensuring compliance, safety, and efficiency.
