ASTM A249 TP316L Bright Annealed Stainless Steel Welded Tubes , Used For Air Coolers

ASTM A249 TP316L stainless steel tubes are typically welded tubes that are used for heat exchanger tubes, boiler tubes and condenser tubes. The "Bright Annealed" (BA) finish denotes a specialized heat treatment performed in a controlled atmosphere (typically hydrogen or vacuum) after welding, resulting in a shiny, reflective, oxide-free surface without the need for subsequent pickling. YUHONG GROUP specializes in manufacturing ASTM A249/ASME SA249 stainless steel welded tubes, and the raw material grades can be TP304/304L, TP316/316L, TP321/321H, TP310S, TP347H, TP904L, etc.. Our factory can produce such stainless steel welded tubes mainly from 6mm to 152.4mm outer diameter. Our ASTM A249 stainless steel tubes are widely used for heat exchangers, heaters, air coolers, condensers, boilers, food processing industry, sugar refinery, oil and gas plant, power generation, and so on.

Regular Sizes:

Parameter	Common Range
Outer Diameter (OD)	6.35mm to 152.4mm (1/4" to 6")
Wall Thickness (WT)	0.5mm to 3.4mm or As Requested
Length per Piece	Single Random Length (SRL): 4.0m – 7.0m Double Random Length (DRL): 7.0m – 13.0m

Chemical Composition:

Element	Composition (Weight, %)
Carbon (C)	≤ 0.035
Manganese (Mn)	≤ 2.00
Phosphorus (P)	≤ 0.045
Sulfur (S)	≤ 0.030
Silicon (Si)	≤ 1.00
Chromium (Cr)	16.0 – 18.0
Nickel (Ni)	10.0 – 14.0
Molybdenum (Mo)	2.0 – 3.0
Nitrogen (N)	≤ 0.10 (max)

Key Advantages and Features:

Superior Corrosion Resistance
Excellent Formability
Weld Seam Integrity
Hygienic & Easy to Clean
High Temperature Stability

Surface Finish Specifications:

Finish Type	Description	Key Characteristic
Bright Annealed (BA)	Mirror-like, highly reflective surface produced by heat treatment in a reducing atmosphere. Oxide-free.	Highest corrosion resistance due to an intact, chromium-rich passive layer. No pickling required.
Pickled (AP)	Chemically cleaned to remove oxides; matte, dull grey finish.	Cost-effective, but rougher. Requires passivation post-pickling.
Mechanically Polished (MP)	Ground and polished post-annealing to achieve a specific shine.	Brighter than AP, but removes the as-annealed pristine surface layer.
