Research significance of heat shrinkable sleeve

Due to the common corrosion problem of steel pipe, the appearance of heat shrinkable winding tape solves this kind of problem

The corrosion problem of steel pipe exists in all departments of national economy and national defense construction, which not only brings huge losses to national economy, but also causes great difficulties to production and life. Under natural conditions (atmosphere, natural water, soil) or man-made conditions (acid, alkali, salt and other media), the electric melting sleeve steel pipe is corroded all the time. It is a kind of spontaneous unnecessary consumption. The fundamental reason of the steel pipeline is that it is in a thermodynamic unstable state. Under the above conditions, they will return to the original relatively stable state, generate iron oxide carbonate, etc., or transform into soluble ions. This process is the corrosion process of metal. According to statistics, the annual output of iron and steel in China is 160 million tons. The annual loss of more than 60 million tons due to corrosion is almost equal to the annual output of Shanghai Baosteel General Iron and steel works. Corrosion is not only a waste of iron and steel resources, but also can shorten the service life of pipelines and equipment due to corrosion. The cost of replacing new pipeline equipment is far more than the price of metal materials itself. Therefore, the production cost is increased and the economic benefits are reduced. The direct and indirect economic losses caused by corrosion are huge. Corrosion products form scale layer, which affects heat transfer and medium flow rate, and reduces heat transfer efficiency. Therefore, energy consumption is greatly increased. The annual economic loss caused by corrosion in China is as high as 280 billion yuan, which is more than the sum of natural disasters such as wind disaster, flood, earthquake and fire.

Corrosion causes various accidents and major disasters. Due to the corrosion of steel pipes and equipment, the production enterprises stopped production and the quality of products decreased. It affects the life supply, gas supply, heating steam or hot water, and brings many difficulties to people's life. In addition to the loss of a large number of useful substances, serious environmental pollution and even catastrophic accidents such as fire, explosion and collapse are caused by the leakage of buried oil and gas, water and other pipelines and pipelines and pipelines and equipment of oil refining, chemical fiber, chemical fertilizer and pharmaceutical. In view of the widespread existence of metal corrosion, in order to prevent or slow down the occurrence of metal corrosion, various metal anti-corrosion technologies and processes have emerged. The popularization and application of new technology, new material and new equipment of metal anti-corrosion can prolong the service life of pipeline equipment, save money and ensure safe production.

With the development of technology, heat shrinkable sleeve has solved many social problems. The innovation of science and technology is the progress of society.
