Zibo Han Zun well-being equipment co>spiralh-hribbed tube heat exchanger tube failure

ProductBrief：
spiral-ribbed tube heat exchanger tube failure is one of the chemical equipment failure. Spiral-ribbed tube heat exchanger Tube bundle is the weak link, and are prone to failure. Tube failure are mainly in the form of costume crack, cut heat transfer performance rapidly dropped, collision damage, pipes, tubes leaked and many other. ��Main causes of tube failure occurs are as follows. 1, the corrosion. Carbon steel or stainless steel heat exchangers, dissolved oxygen-oxygen-induced polarization of corrosion in cooling water extremely serious, rein in life tend to have only a few months or 12, plus media and many are corrosive, such as ammonia and carbonation Tower of cooling water tank,

Zibo Han Zun well-being equipment co>spiralh-hwound heat exchanger selection should pay

ProductBrief：
shell side of the spiral-wound heat exchanger tube side, stress can be any combination of models monitor and nominal pressure shell side pressure is, in determining the maximum allowable working pressure should be checked when a table 6-13, or maximum allowable working pressure, selected according to table 6-13 design temperature the nominal pressure. General is not less than the maximum allowable working pressure and design pressure. For example: type WBH600-2.5/1.6-39~QX, stands for metric tube and shell said the pressure was 2.5MPa and 1.6MPa respectively, if the tube design temperature 150 ��, shell design

Zibo Han Zun well-being equipment co>causes Frost crack phenomena of woundh-htube heat

ProductBrief：
occurs when the wound-tube heat exchanger in winter frost crack phenomena, in order to extend the life-cycle of maintaining wound-tube heat exchanger, first when the introduction of maintenance needs studies have shown that cracking occurs because the wound-tube heat exchanger. ��In operation process of 1, in the winter, heat transfer area than they need too many values and operations workers when they adjust the heating medium flow control heating medium flow is too small, so that fresh air side heat exchanger through the coil is easy to freeze and frost damage to the heat exchanger. 2, due to improper installation of the heat exchanger or piping, heat exchanger low water, then run during the winter, with the extended running time, heat exchanger plates
