Product Description
Product Overview
ASTM A269/312/213 stainless steel seamless coiled tubing designed for heat exchanger applications. These high-pressure coiled universal tubes are manufactured using cold drawn technology and feature pickling and annealing surface treatment for optimal performance in boilers, heat exchangers, water heaters, and air-conditioning systems.
Manufacturing Process
- Cold drawn technology for precise U-bend tube production
- Custom manufacturing according to customer specifications and drawings
- Inert gas (Argon) protection to prevent oxidation during processing
- Comprehensive radius verification for OD and wall thinning compliance
- Multi-position quality testing including physical properties and microstructure analysis
- Visual inspection with dye penetrant testing for waviness and crack detection
- Individual hydro testing at recommended pressures to ensure leak-free performance
