U Tube Heat Exchanger

U tube heat exchanger is a kind of tube and shell heat exchanger, belongs to the petroleum and chemical equipments. This kind of heat exchanger is named after the‘U’shape tube. U tube heat exchanger is composed of some main components like the tube box, shell, and tube buddle. What’s more, it is easy to drying after the U tube heat exchanger hydrotest.

U Tube Heat Exchanger Advantages

• The tube buddle can expand or contract freely, and they will not produce thermal stress due to the temperature difference between the tube and shell, which leads a good thermal compensation performance.
• The structure is simple, with only one tubesheet and less sealing surface, thus,the price is low.
• It is easy to make the u tube heat exchanger cleaning and maintenance, which is because the tube buddle can be drawn from the shell body.
• This kind of heat exchanger has a light quality, is suitable for the situation with high temperature and high pressure.

U Tube Heat Exchanger Design

The biggest difference about u tube heat exchanger compared with other types of heat exchanger is the tube buddle structure, the longer the tube diameter is , the longer the minimum bending radius is. And the u tube heat exchanger bending radius should not less than two times the outer diameter of the heat exchanger tube.
U tube heat exchanger usually designed according to the ASME Code, Section VIII, Division 1. This high load U tube heat exchanger can prevent the stress damage caused by container inflation during the process of heating or cooling. As one end of the tube bundle is float, the heat exchanger can be guaranteed safety even under the extreme heat cycle. It is a ideal design method when the heat medium is steam.
ANSON can manufacture U tube heat exchanger in accordance with the ASME standard, TEMA, and API for 1, 2, or 4 pass U tube heat exchanger, other special requirements are also available.
