Graphite heat exchanger leakage causes and solutions
Release time:
2021-06-16
Everyone should be familiar with graphite, which is found in many devices and materials. Graphite heat exchanger is a kind of equipment to process graphite material, its appearance meets the market demand for graphite, but if there is a failure, it will greatly affect the characteristics of graphite. When there is a two-phase medium leakage problem, first of all, we should check whether there is a problem with the quality of graphite, and then check whether the graphite heat exchanger bonding is normal, whether there is a dissolution phenomenon , aging or deterioration, the solution: the quality of the problem needs to be replaced, the glue needs to be re-glued, balanced the impact of the force, and drained of water in advance. Graphite tube fracture may be the equipment in the operation of the feed rate
With the rapid increase in the level of production, more and more new materials are beginning to appear in our production, many of which have their own characteristics, and these properties are used in our production with very effective results.
Everyone should be familiar with graphite, which is present in many devices and materials. The graphite heat exchanger is a device for processing graphite materials.

Graphite tube breakage may be caused by the equipment in the operation of the feed rate is too fast, the solution: to ensure smooth operation, the system vibration, the material flow is not smooth, resulting in unstable operation, the solution: adjust the material balance and system operation before operation. As long as the problem is found, it is easy to solve the graphite heat exchanger failure and deal with the problem correctly.
Graphite has very good characteristics, so graphite-based process equipment is widely used in our lives, graphite heat exchanger as one of the widely loved.
Graphite heat exchanger has good corrosion resistance, the heat transfer surface is not easy to scale, good heat transfer performance. However, graphite is brittle, low bending and tensile strength, so it can only be used at low pressure, even with good pressure-bearing capacity of the block structure, its working pressure is generally only 0.3 ~ 0.5MPa.
Graphite heat exchanger is expensive, bulky and not much use, mainly used for hydrochloric acid, sulfuric acid, acetic acid, phosphoric acid and other corrosive media heat transfer, such as acetic acid, acetic anhydride condenser, graphite heat exchanger leakage generally have the following three reasons. One point, the problem may be in the phenolic graphite profile tube body, when the tube body is found to have cracks, roughness, blistering and other phenomena, you can determine the problem, due to these surface phenomena, the quality of the tube body is very poor, and in the process of operation, in the role of a variety of external pressures, the tube body can not be used normally, the tube body leakage.
