LOW FIN TUBES

LOW FIN TUBES

The extended surface by integral low finning process, it provides a better heat transfer efficiency and the client can install the equipment with smaller space and sizes.

As an expert with long-standings extensive experience, we are able to suggest most competitive condition to our customer's needs.

The materials are in available (Seamless tube type recommended)

  1. CS and Alloy steel tubes
  2. Stainless steel tubes
  3. Depulex and Super Duplex
  4. Copper alloy tubes
  5. Titanium tubes

All finned tubes are 100% Hydrostatic tested to detect the leakages ensure tubes are no damaged during finning. )
