Application: Boiler, Superheater, Heat-Exchanger, Condenser
Main Standard: ASTM A249
Main Grade: 304, 316L; 1.4301, 1.4404
Outer Diameter: 20-38mm
Wall Thickness: 1-3mm
Length: fixed 6m or as customers’ requirement
Surface Treatment: pickling or as customers’ requirement
How is it Measured? Outer Diameter (A) X Schedule or Wall Thickness (B) X Length
PS: 304 VS 316L
| 304 benefits | 316L benefits |
| Lower cost | Superior corrosion |
| Easier to weld and form | Stronger and more durable |
| Able to withstand corrosion from most oxidizing acids | Better for marine, offshore and washdown applications |
Advantages Of Welded Tubes & Pipes
A. Lower cost compared to the equivalent seamless alternative
B. Short lead time
C. Better surface finishing of outside and inside, the internal material surface for welded tubes can be checked prior to manufacture
D. Thinner wall thickness and more uniform
E. Tighter tolerance
