  • Heat exchanger tubes are used in energy and chemical industry for heating the buildings, water etc. The heat exchanger tubes make it possible to transfer thermal energy from one media to another.
  • Heat exchanger tubes are usually cold drawn, upon agreement it is olso possible to supply hot rolled tubes. A delivery of tubes with a medium wall thickness must be agreed while ordering.
