ASTM A249 TP304 Stainless Steel Welded Used In Oil Refining Projects
ASTM A249 is the standard for stainless steel welded tubes, the wall thickness can be avg. or min. wall thickness, usually clients will choose min. wall thickness, these tubes intended for such use as boiler, superheater, heat exchanger, or condenser, etc.

Advantages
ASTM A249 TP304 welded tubes are a popular choice for heat exchangers, condensers, and piping in oil refineries due to their cost-efficiency, corrosion resistance, and ease of fabrication. The following are their key advantages in refining applications:
1.Must be cost-effectiveness: lower cost than seamless tubes,making them ideal for large-scale refinery projects.
2.Corrosion resistance for mild environments, performs well in: cooling water systems; steam condensate lines; hydrocarbon service.
Oxidation Resistance: handles high-temperature steam (up to 870°C continuous, 925°C intermittent).
* Limitation: not suitable for chloride-rich, sour (H₂S), or acidic environments, need to use TP316L or duplex stainless steel instead.
3.High-Temperature Performance: stable at elevated temperatures , maintains strength in refinery heaters and heat exchangers.
Alternatives Materials in Some Situation
*Use TP316L, duplex 2205, or inconel for sour gas (H₂S) service.
*Use super duplex or titanium for chloride-rich environments (seawater cooling).
*Use TP321 (ti-stabilized) or TP347 (nb-stabilized) for some very high temps enviroments (>925°C).
Applications
1.Heat Exchangers & Condensers
· Shell-and-tube heat exchangers for freshwater cooling (low chloride content)
· Process Condensers
2.Process Piping & Tubing
· Sweet Crude Service
· Utility Steam Lines
3.Fired Heaters & Boilers
· Convection Section Tubes
· Boiler Feedwater Systems
4.Storage & Handling
· Tank Heating Coils
· Vapor Recovery Units (VRUs)
