The wear pipe is a piping system for conveying high-velocity, high-concentration solid particulate media. Its inner wall is specially treated to provide excellent wear resistance and extend the service life of the pipe. Rubber-lined composite steel pipe is a common type of wear-resistant pipe, which consists of an outer steel pipe and an inner rubber lining.
The natural rubber (NR) lining is characterized by its high abrasion resistance and corrosion resistance, rendering it well-suited for the conveyance of general solid particles of media, such as ore and coal. The styrene-butadiene rubber (SBR) lining, on the other hand, exhibits high abrasion resistance and strength, rendering it suitable for the conveyance of abrasive media, such as coal mill dust, powder, and dust.
The CR (neoprene rubber) lining exhibits superior oil resistance and ozone resistance, rendering it well-suited for conveying oil-containing media, chemical media, and ultraviolet radiation environments.
The EPDM (ethylene-propylene rubber) lining boasts exceptional abrasion resistance, corrosion resistance, and high-temperature resistance, rendering it an optimal choice for transportation in high-temperature environments, such as flue gas discharge systems and high-temperature ash transportation.
Rubber-lined composite steel pipes are employed in a number of fields and contexts, including:
The chemical industry is one of the primary applications of rubber-lined composite steel pipes. These pipes are particularly suited to the handling of corrosive media, high-temperature media, and high-pressure media. They can be used to convey acids, alkalis, solvents, salts, and various chemicals, including those that are corrosive to metals.
The oil and gas industry is another area in which rubber-lined composite steel pipes are extensively utilized. These pipes are employed in the extraction, transportation, and storage of oil and gas. They are utilized for the transportation of corrosive media, reservoir water, and natural gas, as well as in oil wells to enhance the efficiency of oil recovery.
The power industry employs rubber-lined composite steel pipes for the conveyance of cooling water, circulating water, and wastewater. These pipes are also utilized for the conveyance of coal ash, coal mill emissions, and other solid particulate matter, as well as coal and oil fuels in thermal power plants.
The mining industry is another area in which rubber-lined composite steel pipes are extensively utilized. These pipes are employed in the conveyance of ores, coal, and tailings. In order to withstand the rigors of the mining environment, which includes the potential for abrasion and corrosion, as well as the impact of high-velocity fluids and solid particles, the pipes must be constructed from materials that are resistant to these ills.
In brief, rubber-lined composite steel pipe are employed in a multitude of industrial sectors, including the chemical, petroleum, natural gas, food, pharmaceutical, electric power, and mining industries. This is due to their exceptional corrosion, abrasion, and high-temperature resistance.
