Three major factors in repairing graphite heat exchangers
Release time:
2022-04-22
Graphite heat exchanger repair is a technical test work when the chemical enterprise plans to stop the maintenance, involving anti-corrosion treatment, diagnostic testing, pressure adjustment and other programs. Therefore, it has also become a content to assess the strength and qualification of graphite heat exchanger production enterprise. This article introduces three points that should be noted in graphite heat exchanger maintenance.
Graphite heat exchanger repair is a technical test work when the chemical enterprise plans to stop the maintenance, involving anti-corrosion treatment, diagnostic testing, pressure adjustment and other programs. Therefore, it has also become a content to assess the strength and qualification of graphite heat exchanger production enterprise. This article introduces three points that should be noted in graphite heat exchanger maintenance.
1. graphite heat exchanger manufacturer maintenance program design, according to the design and production of graphite equipment to decide, according to the material medium to develop anti-corrosion protection treatment program, and then assess the level of chemical cleaning of the equipment, give priority to cleaning the surface of the equipment, to find out which parts of the graphite heat exchanger parts are defective, according to the actual severity of the damage to the assessment, and then cleaning.
2. According to the professional level of graphite heat exchanger repair manufacturers, according to the standard process of work, graphite heat exchanger inspection and pressure test are required. The purpose of this is to prevent any parts from being lost in order to find out where there is no leakage. The above operation process requires maintenance personnel rigorous work attitude and standardized guidance of the professional process, in order to ensure that the graphite heat exchanger material media cleaning is completed, and therefore is also an important indicator to test the degree of professionalism of the manufacturer.
3. The need for regular cleaning. In order to ensure the orderly production program and the entire chemical enterprise production system, the need for regular cleaning graphite heat exchanger. In this process, it is important to note that the physical properties of graphite are lower than metal, especially the maintenance time of the tube heat exchanger is longer than the round block graphite heat exchanger. Therefore, when cleaning graphite heat exchangers, it is prohibited to use metal pipe fittings to unclog them. Regular cleaning can prevent scale buildup to block the tube holes, thus avoiding the economic loss of equipment downtime caused by graphite heat exchanger blockage. These are the three main factors that should be noted in the maintenance of graphite heat exchangers.
