We mainly design and manufacture heat exchangers of fixed tube plate type, tank head type, U tube type, stuffing box type. According to the requirement of the craft, in order to strengthen the efficiency and reduce the energy cost, we design various kinds of high efficient heat exchangers, which are used in many fields, and can be divided into several types, such as ripple pipe type, corrugated pipe type,bellows tube type, fin tube type, helical baffle type.
