Online bright solution heat treatment production line for stainless steel tubes
Stainless Steel Pipe Online Bright Solution Heat Treatment Production Line

Independently developed by Ningbo Dedao Thermal Engineering Equipment Co., Ltd., utilizing air-cooled induction heating and rapid cooling technology, specifically designed for stainless steel welded pipe solution treatment.

Technical Features
- Air-cooled induction heating: only the induction coil requires water cooling; main/auxiliary units are air-cooled, no external cooling water system needed
- Rapid cooling: fast cooling after heating ensures complete austenite solution, bright surface, and uniform microstructure
- Compact 2-meter heating unit, easy to integrate into production lines

Core Specifications
- Energy consumption: ~300 kWh/ton
- Modes: online continuous / offline batch processing
- Applicable materials: 304, 316L and other austenitic stainless steels

Product Advantages
1. Water-saving — air-cooled design drastically reduces water usage vs. water-cooled equipment
2. Energy-efficient — 30-50% more efficient than electron tube systems, 10-30% more than thyristor systems
3. Zero tube burst — air cooling fundamentally eliminates internal tube burst risk
4. Ultra-low failure rate — 24/7 continuous stable operation
5. Modular — 2-meter units, flexibly combinable and expandable

Applications
- Online solution treatment for stainless steel welded pipes (integrated with pipe production lines)
- Offline solution treatment for stainless steel pipes
- Bright annealing of tubular products

Track Record
Over 20 production lines delivered and operating stably, with continuous repeat orders.
