Stainless Steel Heat exchanger Tube
Heat exchanger tube in an extensive range of austenitic stainless steels, duplex stainless steels, nickel alloys, titanium and zirconium, suitable for all types of heat exchangers, such as seawater coolers, condensers, evaporators, heaters and reheaters.
Technical parameters
- OD 12.7- 38 mm
- Bending radii from 1.5 x OD up to 1,250 mm. Minimum bending radii for OD over 28 mm after agreement.
- Leg length min. 1,000 mm.
- Leg length max. 12,000 mm.
- Heat treatment for radii up to 1,000 mm.
Heat treatment
If specified, we are equipped to carry out heat treatment of bends plus minimum 150 mm of leg.
- Furnace is computer controlled and all data is recorded.
- We use an Argon protective atmosphere inside the tubes.
- We can supply all types of annealing; solution annealing, stress relieving and stabilization.
Packing
- In strong, open or closed wooden boxes, depending on destination – max 8,000 kg.
- Ends of tubes protected by plastic caps.
- Vertical separators for each radius.
- Chloride free plastic separators between each row, every 2 meters.
- Each bundle is covered with plastic.
- Customers can provide a packing drawing or Sandvik can prepare a packing plan.
- Packing lists, covered with plastic, are placed on each wooden box for easy identification of order details, including exact list of radii and lengths inside.
