Does semi welded plate heat exchanger real expensive？

Semi welded plate heat exchanger are used for evaporation, condensation, ammonia refrigeration condition, to gasket and plate it has high pressure, corrosion resistance, sealing requirements, the test of the manufacturing process is very high, so a lot of people feel very expensive, and turned him into the arms of the tube and shell heat exchanger.

Cost is value. Today, let's talk about the cost of the semi - welded plate heat exchanger is really expensive?

Assuming that both the plate type and the tube type are made of the same material, the cost of the plate type is more in the process and the tube type in the raw material under the same condition of corrosion resistance and temperature resistance. As we all know, tube heat exchanger, although not leakage, pressure, temperature resistance, but the large volume is undeniable; And plate, in this difficult working condition, to do not leak, the importance of welding can be seen.

Take Qingdao Ruipute for example, the laser welding technology adopted has a small impact on the internal stress of the plate, will not have an impact on the heat transfer area, heat transfer area will not reduce a cent, and there will be no fluid dead Angle at the welding place, resulting in corrosion.

That's how it adds value, and how it reduces costs by comparison:

1. Compared with tube cleaning, plate cleaning is simply not too convenient. Moreover, if the tube is to be cleaned, chemical cleaning is needed.

2. Heat exchange efficiency plate can achieve the purpose of heat exchange according to working conditions, free design process combination and import and export mode. It occupies a small area and is actually a manifestation of efficient heat exchange.

Chinese people always like to do addition and multiplication, but do not want to do division by themselves, this is like installment payment, only pay 100 yuan a month, a mobile phone to take home; But the tubular heat exchanger manufacturer will never tell you the daily or monthly cost of the tubular heat exchanger, because it must be uneconomical, not counting the time cost.

If Ruipute tells you: efficient heat transfer, 10 yuan per day, minimum life guarantee of x years. Do you still think a semi-welded heat exchanger with long life and high efficiency is really expensive?
