Expert Guide to Stainless Steel Heat Exchanger Tube

Why Choose Stainless Steel for Heat Exchangers?

Stainless steel is ideal for heat exchangers due to its corrosion resistance, handling harsh environments. Grades like 304, 316 resist acids, saline conditions. It offers excellent thermal conductivity, high strength for 60 bar pressures, hygienic surfaces for food use, and sustainability with 84% recycled content, ensuring cost-effective, durable performance.

How long do stainless steel heat exchangers last?

Stainless steel heat exchangers last 20-40 years, depending on conditions and maintenance. Grade 316L in seawater systems lasts 25-30 years. Regular cleaning, avoiding chloride exposure, and quality manufacturing (pickling, annealing) extend lifespan. Proper care in non-corrosive environments can push durability beyond 40 years.

What is the standard tube length for a heat exchanger?

Straight tubes in heat exchangers shell-and-tube designs, with subtypes having pony and straight mountings, have a standard tube length of 6-12 meters (20-40 feet). For significantly large applications, custom lengths extend up to 30 meters. Complicated designs make use of U-bend tubes, which have lower effective lengths (3-6 meters per leg) to accommodate exchanger dimensions.

What is the tube thickness for heat exchanger?

For heat exchangers, tube thickness varies between 0.5 mm and 2.5 mm. More commonly used are 1.0-1.65 mm tubes considering balance. 2.0-2.5 mm may be used for high-pressure systems (60 bar), whereas low-pressure HVAC applications prefer 0.5-1.0 mm to improve heat transfer efficiency.

Is a bigger heat exchanger better?

A bigger heat exchanger isn’t always better. It increases heat transfer but raises costs, space needs, and pressure drops. Optimal size depends on heat load, flow rates, and space. Compact U-bend or finned designs can achieve high efficiency in smaller footprints, ideal for HVAC or marine systems.

What is the best shape for a heat exchanger?

Shell-and-tube with U-bend or finned tubes is best for most heat exchangers, offering versatility and high-pressure capability. U-bends suit compact spaces, finned tubes enhance air-cooled systems, and straight tubes with polished finishes are ideal for hygienic applications like food processing, balancing efficiency and maintenance.

What is the most common size of tube in heat exchanger?

In heat exchangers, the most frequently used tube size is between 19-25 mm or 0.75-1 inch in outer diameter (OD). The shell and tube type, utilized in petrochemical and HVAC industries, commonly uses a 19 mm stainless steel tube with 1.0-1.65 mm thickness due to its strength, cost, and efficiency in heat transfer.

What is the spacing between heat exchanger tubes?

Tube spacing (pitch) in heat exchangers is 1.25-1.5 times the OD, typically 23.75-28.5 mm for a 19 mm tube. A minimum 6 mm gap ensures flow distribution and cleaning. Triangular or square arrangements follow TEMA standards, preventing fouling and optimizing heat transfer in shell-and-tube designs.
