Tubular heat exchangers are really important devices in lots of industries. They transfer heat between two fluids without let them mix together. This help in many process, like heating water inside boiler or cooling oil in car engine. At Shanghai Changlong, we make high-quality scraped heat exchanger. These are design to be efficient and last long time. They got tubes where one fluid flow inside, and another fluid go around the outside. This way maximize the heat transfer, so they work very good for different application. And we will talk about some common problems people face with tubular heat exchangers and why they good choice for heat transfer in many process.
