About Heat Exchanger Tubes

Heat exchanger tube specifications depend on the application, fluid, pressure, temperature, corrosion requirements, and applicable design codes. A typical specification includes the following:

Parameter	Typical Specification
Material	ASTM A179, ASTM A213, ASTM A249, ASTM B111, ASTM B163
Tube Type	Seamless or welded
Outside Diameter (OD)	12.7 mm (1/2"), 15.88 mm (5/8"), 19.05 mm (3/4"), 25.4 mm (1")
Wall Thickness	0.893.4 mm (typically 1812 BWG)
Length	130 m depending on exchanger design
Surface Finish	Mill finish, polished, or bright annealed
Tube Ends	Plain end, beveled, expanded, or threaded
Manufacturing Standard	ASME Section II, TEMA
Design Code	ASME Section VIII Division 1
Hydrostatic Test	As specified by ASTM or purchaser requirements
Eddy Current Test	Optional or mandatory depending on service
Hardness	As specified by material standard
Corrosion Allowance	Based on process conditions

Common tube materials

Carbon steel: ASTM A179, ASTM A214
Stainless steel: ASTM A213 TP304, TP304L, TP316, TP316L, TP321
Duplex stainless steel: ASTM A789
Copper alloys: ASTM B111
Titanium: ASTM B338
Nickel alloys (Inconel, Monel): ASTM B163, ASTM B165

Typical dimensions

Outside diameter: 12.7 mm, 15.88 mm, 19.05 mm, 25.4 mm
Wall thickness: 18 BWG (1.24 mm), 16 BWG (1.65 mm), 14 BWG (2.11 mm), 12 BWG (2.77 mm)
Tube length: 212 m for standard exchangers; up to 30 m for special applications.

If you're preparing a procurement document, a typical specification might read:

Heat exchanger tubes shall be seamless ASTM A213 TP316L stainless steel, 19.05 mm (3/4 in.) OD 1.65 mm (16 BWG) wall thickness 6000 mm length, solution annealed, plain ends, manufactured and tested in accordance with the applicable ASTM standard and TEMA requirements, suitable for service under the specified design pressure and temperature.

If you need specifications for a particular service (e.g., refinery, power plant, seawater cooling, condensers, or food processing), I can provide a more targeted recommendation.
