Application of heat exchange tube in chemical industry

There is a great demand for heat exchange tubes. The main application specifications of the industry include: 304 321 316 316L 347 317L etc. the outer diameter is about ￠ 18 - ￠ 610 and the wall thickness is about 6mm-50mm (generally the medium and low pressure pipeline with the specification above Φ 159mm is selected). The detailed application scope is: furnace tube material pipeline heat exchanger tube etc.

Heat exchange tubes are mainly used for heat exchange and fluid transportation. The domestic market capacity is about 160000 tons per year. Due to the strict requirements they are mainly imported.

Heat exchange tube is mainly used in the heat exchanger and fluid tube market of chemical industry and chemical fertilizer. Because of its high strength stress resistance corrosion resistance and economy its annual consumption is about 4000-5000 tons.

Stainless steel oil casings stainless steel non magnetic drill collars super ferritic stainless steel Cr13 Cr25 and other oil casings with high resistance to CO CO2 and Cl corrosion used in oil field drilling and production are roughly estimated to be over 10000 tons per year and about 40000-50000 tons per year after 3-5 years. At present most of such stainless steel heat exchange tubes still rely on imports.

In addition the potential market of petrochemical industry is the large-diameter oil cracking furnace pipe and low-temperature delivery pipe. Because of its special heat and corrosion resistance requirements and inconvenient maintenance of equipment and devices the equipment is required to have a long service life cycle and the mechanical properties and operational properties of the pipe are optimized through the control of material composition and special heat treatment methods. Another potential market is steel pipe for fertilizer industry (urea phosphate fertilizer) mainly 316lmod and 2RE69. At present the above stainless steel heat exchange tubes mainly rely on imports.

As an important part of the chemical industry the petrochemical industry includes many consumer sectors such as pesticide fertilizer rubber synthetic materials and other industries. Petrochemical industry is the fundamental industry of economic development which involves many aspects of the real economy.
