Carbon Steel Heat Exchanger Tubes Material and Grades

What Is the Difference Between ASTM A179 and ASTM A214 Carbon Steel Heat Exchanger Tubes?

The difference is the seam. ASTM A179 tubes are seamless and cold drawn, so they have no weld and hold the tightest size. ASTM A214 tubes are electric resistance welded, so they carry one heat-treated seam and cost less. Both are low carbon steel, both are soft enough to roll into a tubesheet, and both have the same low strength levels, so the choice comes down to price, pressure, and your design code.

Choose A179 when the exchanger runs at higher pressure, when the fluid is fouling or aggressive, or when the code gives seamless tubes a higher allowable stress. Choose A214 for low and medium pressure duties where cost matters.

Carbon Steel Heat Exchanger Tubes Chemical Composition

Chemistry controls how soft, ductile, and weldable the tube is. Values are weight percent, maximum unless a range shows.

ASTM Heat Exchanger and Condenser Tubes

European Pressure Tubes (EN 10216-2)

Carbon Steel Heat Exchanger Tubes Mechanical Properties

Mechanical properties show how much load the tube carries before it stretches (yield) or breaks (tensile). Values are minimum unless marked max. A low maximum hardness matters here, because the tube must stay softer than the tubesheet for a tight rolled joint.

Carbon Steel Heat Exchanger Tube Size and Weight Chart

Heat exchanger designers need more than weight, so this chart also gives the inside diameter, the flow area inside the tube, and the outside surface area per metre of tube. Weights are for carbon steel.

To work out the weight of any size, use Weight (kg/m) = (OD − Wall) × Wall × 0.02466, with both values in mm. For heat transfer area, multiply the outside surface per metre by the tube length and the number of tubes.

Common Materials Used in Carbon Steel Heat Exchanger Tubes

The material grade affects how heat exchanger tubes perform under different temperatures, pressures, and fluid conditions. We supply carbon steel tubes for heat exchangers, condensers, boilers, and low-temperature applications, with the material selected according to the required standard and service conditions.

ASTM A179: Low-carbon seamless tubes for heat exchangers and condensers.

ASTM A214: Welded carbon steel tubes for heat exchanger and condenser applications.

ASTM A192: Seamless tubes for high-pressure boiler and heat transfer service.

ASTM A210: Grades A-1 and C for boiler and superheater applications.

ASTM A334: Grades 1, 3, and 6 for low-temperature service.

Our role as Carbon Steel Heat Exchanger Tubes Suppliers includes providing the required grade, size, wall thickness, and delivery condition to match the applicable specification. Material test certificates, heat numbers, and inspection documents can also be supplied for proper traceability.

Available Sizes, Dimensions and Tolerances

We supply carbon steel heat exchanger tubes from 1/2" to 2" OD, in walls from 16 BWG (1.65 mm) to 10 BWG (3.40 mm), and larger sizes up to 4" OD on request. Tubes do not use schedule numbers. You give the outside diameter and the wall thickness, and the standard sets how far each can vary. BWG is the gauge number for wall thickness, and a lower BWG means a thicker wall. Always tell us whether your design uses the minimum wall or the average wall, because ASTM A179 and A214 define them differently, and your pressure calculation depends on the answer.

For U-bend tubes, remember that the outer side of the bend thins as the tube curves. TEMA guidance generally sets the minimum bend radius at about 1.5 times the tube OD. Tell us your bend radius and your minimum wall after bending, and we will confirm the wall to order before bending.

Standard lengths are 6 m, 9 m, and 12 m, plus exact cut lengths. As a carbon steel heat exchanger tubes supplier in India, we hold the common sizes in stock, subject to availability.

Carbon Steel Heat Exchanger Tubes We Manufacture and Supply

Our range covers ASTM A179 seamless tubes, ASTM A214 welded tubes, ASTM A192 and A210 tubes, ASTM A334 low-temperature tubes, and EN 10216-2 tubes for heat exchangers, condensers, feedwater heaters, and coolers.
