Pipeline transportation is more and more convenient and popular, and the application of pipeline transportation is more and more common, and the geographical environment is also complex and diversified. As embedded Waterproof casing In other words, the models and materials selected in different regions will also be different. So how to choose waterproof casing in the face of complex environment?
When the waterproof casing is applied, the application environment is suitable, and the performance of the product will also be improved. For example, the service life of the waterproof sleeve under normal room temperature conditions is much longer than that under high temperature environment. Therefore, the application index of the product has a great impact on the product.
In general environment, the damage indexes of waterproof casing include low temperature, heat resistance, tensile and elongation, aging performance, soluble components, etc.
Before installation, attention should be paid to the application environment of waterproof casing products. For example, the temperature of medium is relatively low and the temperature of application part is relatively high. In this way, the cross of cold and hot is not good for the application of the product. Similarly, the heat resistance of the product also needs special attention.
In terms of tensile force and elongation, the product should be measured before application to measure the pressure of the product, the pressure of the pipeline, size and so on. So that the pressure of the product can not be easily broken in the application environment. Ensure the normal operation of the pipeline.
It is necessary to use waterproof casing to maintain the through wall pipe and wall in the building, but the humidity, cold and oxygen enrichment of the building environment will lead to the corrosion of the waterproof casing in the application process, so the sealing and strength will be reduced. Therefore, we should do a good job in the case of installing waterproof casing. The current pipeline anti-corrosion technology avoids the corrosion of pipeline by soil, air and transportation medium (oil, natural gas, etc.). Most of the pipelines transporting oil and gas are in complex soil environment, and the medium transported is also corrosive, so the inner and outer walls of pipelines will be corroded. Once the pipeline is corroded and broken, it will lead to leakage of oil and gas wells, which will not only make the transportation end broken, but also cause environmental pollution, and even cause fire accidents and adverse effects.
The corrosion of waterproof casing is caused by the chemical and electrochemical action of the media around the pipeline. According to the corrosion parts of the pipeline, it can be divided into inner wall corrosion and outer wall corrosion; according to the shape of pipeline corrosion, it can be divided into corrosion and partial corrosion; according to the principle of pipeline corrosion, it can be divided into chemical corrosion and electrochemical corrosion.
