Heat Exchanger Tubing

SBER´s heat exchanger tube portfolio includes a range of more than 20 steel grades between austenetic (standard and heat resistant), duplex, super austenitic and high nickel alloy. The tube size range consists of outside diameters ranging from 12 mm to 60 mm and wall thickness from 0.8mm to 4mm. SBER can supply both, straight as well as U-bend tubes with maximum length up to 37 meters.

Special size requirements can be considered for production. Tubes are manufactured according to all major international standards such as ASTM/ASME/EN/DIN/GOST. SBER supplies heat exchanger 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 extrusion process followed by pilgering and/or drawing. Our facilities are equipped with all the machines required to cover the process with a high quality results (extrusion press, stretch reducer, pilger machines, draw benches, straightening
machine, degreasing facility, bright annealing furnaces and stabilization furnaces). SBER also has key shop approvals such as TUV and NORSOK.

This qualification was 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 and critical pitting corrosion test as well as microstructure analysis. Any other special testing requirement can be carried out at third party labs.
