Stainless Steel Heat Exchanger Tube

Stainless Steel Heat Exchanger Tube is generally used for boiler, heat exchanger, condenser, standards are A249 welded tube and A213 seamless tube, 304 / 304L, 316 / 316L stainless steel grades.

Heat Exchanger Tube is major component part in heat transfer system, which transfer heat from one fluid to another fluid, shell and tube heat exchanger is the most popular type, and requiring number of tubes inside it to form tube bundle, these tubes insert and joint to tube sheet as a whole。

Stainless Steel Material

We specialize in stainless steel tube for heat exchanger, stainless steel material has a ideal properties to suit heat exchanger applications, obviously, different grades provide special properties。

  • 304/304L
  • 316/316L
  • 321
  • 439
  • 446

Duplex steel

  • S31803/2205
  • S32750
  • S32760



Welded, Seamless Tube

澳门凯发娱乐Welded and seamless tubes are available for heat exchanger, main specifications have ASTM A249 and ASTM A213 separately, we manufacture welded tubes using TIG welding method starting from coil strip, cost effective and tight tolerance are main advantages for welded tube。

Seamless tubes is another way to be produced, made from billet by cold drawing and cold rolled extrusion process, compared to welded tube, seamless type tube usually have a long life usage, not easy to corrosion.

Tube Sizes and Dimensions

Normal tube outside diameters are 15.88 mm, 19.05 mm, 25.4 mm and 31.8 mm, smaller or larger diameter tube is also offered, tube wall thickness ranges from 0.71 to 2.11 mm, BWG 14 to 22, thinner wall for welded tube is available.

Average wall and minimum wall are options according to heat exchanger designers calculation, also choose straight tubes and U shape tubes。

Tube Forms

  • Straight Tube
  • U Bend Tube
  • Coil Tubing
  • Finned Tube

Tube Expansion

Tubes are commonly expanded to joint to tube sheet, according to failure analysis, inferior tube is likely to damage or corrosion after expansion, because heat exchanger is applied in high temperate, low temperate and corrosion environment, high quality tubes are strongly required.
