Heat Exchanger Tube
Heat Exchanger Tube
  • DESCRIPTION
Zhongrui manufactures and supplies heat exchanger tubes in an extensive range of austenitic stainless steels, duplex stainless steels, suitable for all types of heat exchangers, such as seawater coolers, condensers, evaporators, heaters and re-heaters. Special size requirements can be considered for production. Tubes are manufactured as per all major International standards such as ASTM/ASME/EN.

Zhongrui supplies heat exchangers tubes for several critical applications which require high corrosion resistance materials and highest quality standards to be maintained. Some of these applications include condensers, coolers, evaporators, heaters in Refinery, Petrochemical , Chemical , Oil/Gas , Organic and Inorganic acids, Hydro metallurgy, Power generation and Desalination.
The heat exchanger tubes are manufactured by Piercing process followed by pilgering/drawing. Our facilities are equipped with all the machines required to cover the process with a high quality results (Piercing, pilger machines, draw benches, straightening machine, degreasing facility and solution annealing furnace).

This process is completed with our in house quality testing of chemical composition and mechanical properties (Tensile, Impact, Hardness ). Non-destructive testing includes Hydro test, Eddy current test and Ultrasonic test . Quality department is also equipped to carry out in house corrosion tests such as inter Granular corrosion test besides Micro structure analysis. Any special testing requirements can be carried out at Third party Labs.

Zhongrui has approvals from several national and international clients . References includes supplies made to customers / end customers in Middle east , Europe and North America.
