ASTM A249 TP316L welded tubes are produced through controlled forming, welding, heat treatment and finishing processes. During manufacturing, special attention is given to weld quality, surface condition, dimensional accuracy and corrosion resistance.
| Manufacturing Step | Key Control Points |
|---|---|
| Tube Forming | Accurate strip forming to maintain tube geometry |
| Welding | Controlled welding process with uniform weld penetration |
| Heat Treatment | Solution treatment to achieve required metallurgical condition |
| Surface Finishing | Cleaning, pickling or surface treatment according to project requirements |
| Inspection | Dimensional inspection, mechanical testing and weld quality examination |
Typical inspection requirements include tensile testing, flaring or flange testing, hydrostatic or nondestructive electric testing, and weld area evaluation according to ASTM A249 requirements.
| Product Item | Capability |
|---|---|
| Material Grade | ASTM A249 TP316L |
| Tube Type | Welded stainless steel heat exchanger tube |
| Application | Boiler, heat exchanger, condenser and process equipment |
| Supply Form | Straight tubes, customized lengths and project-based supply |
| Related Products | Tube bundles, U tubes, tube sheets, baffles and heat exchanger parts |
ASTM A249 TP316L welded tubes are commonly applied in:
- Shell and tube heat exchangers
- Chemical processing equipment
- Condensers and cooling systems
- Marine heat exchange equipment
- Pharmaceutical and food processing systems
The main advantages include good resistance to chloride-containing environments due to molybdenum addition, suitable weldability from low carbon content, and reliable performance in heat transfer equipment where corrosion resistance and long service operation are required.
Yuhong Group also provides customized solutions based on customer requirements, including tube dimensions, surface finish, inspection scope, packaging method and integration with complete heat exchanger manufacturing.
