With the rapid improvement of production levels, more and more new materials begin to appear in our production. Many materials have their own characteristics. These characteristics have been applied in our production and have produced very effective results.

Everyone should be familiar with graphite, which is present in many equipment and materials. Graphite heat exchanger is a kind of equipment for processing graphite materials. Its appearance meets the market's demand for graphite, but if it fails, it will greatly affect the characteristics of graphite. When a two-phase medium leakage problem occurs, first check whether the graphite quality is faulty, and then check whether the graphite heat exchanger is properly bonded, whether there is dissolution, aging or deterioration, and the solution: the quality problem needs to be replaced, the glue Need to re-gluing, balance the impact, and drain the water in advance. Graphite tube fracture may be caused by too fast feeding speed of the equipment during operation. Solution: Ensure stable operation, large system vibration, poor material flow, and unstable operation. Solution: Adjust material balance and system operation before operation . As long as the problem is found, it is easy to solve the fault of the graphite heat exchanger and deal with the problem correctly.

Graphite has very good characteristics, so graphite-based process equipment is widely used in our lives, and graphite heat exchangers are widely loved as one of them.

The graphite heat exchanger has good corrosion resistance, the heat transfer surface is not easy to scale, and the heat transfer performance is good. However, graphite is brittle and has low bending and tensile strength, so it can only be used under low pressure. Even if it is a block structure with good pressure bearing capacity, its working pressure is generally only 0.3 to 0.5 MPa.

Graphite heat exchanger is expensive, bulky and not used much. It is mainly used for heat exchange of corrosive media such as hydrochloric acid, sulfuric acid, acetic acid, phosphoric acid, such as condensers of acetic acid and acetic anhydride. Graphite heat exchanger leaks generally have the following three Kind of reason. One thing is that the problem may lie in the tube body of the phenolic graphite special-shaped tube. When the tube body is found to have cracks, roughness, blistering, etc., the problem can be determined. Due to these surface phenomena, the quality of the tube body is very poor. During operation, under the action of various external pressures, the pipe body cannot be used normally and the pipe body leaks.
