Backpack-style ceramic-lined wear-resistant tee (multi-way)

Backpack-type ceramic-lined wear-resistant tee (multi-way), specifically designed for harsh conditions, is significantly different from conventional tee (multi-way). It adds a "backpack" structure at easily worn branch and corner points on the basis of conventional ceramic-lined tee (multi-way). The "backpack," made of high-strength steel, is filled with high-wear composite materials, working in synergy with the alumina ceramic layer on the inner wall to greatly enhance anti-scouring and anti-impact capabilities. In multi-pipe material diversion scenarios, it can effectively handle complex flow directions, with a service life at least 2 times longer than conventional tee (multi-way), making it suitable for material transport systems in industries such as mining, power, and chemical.   Product Performance   (1)Excellent wear resistance：The SHS ceramic-lined composite steel pipe, with their inner lining made of alumina ceramics (α-Al2O3), exhibit a Mohs hardness of up to 9.0, equivalent to HRC90 or higher. Therefore, they possess high wear resistance to abrasive media conveyed in industries such as metallurgy, electric power, mining, and coal. Industrial operation confirms that their wear-resistant lifespan is ten times or even several tens of times longer than quenched steel.   (2) Low operating resistance: The SHS ceramic lined composite steel pipe is smooth and has permanent anti-corrosion properties. Fluid dynamics tests show that its inner surface roughness is significantly lower than that of metal pipes, with a clear water friction coefficient of only 0.0193 (lower than that of seamless steel pipes). Coupled with its unique surface self-optimization effect (where the friction coefficient continuously decreases during operation), it can greatly reduce fluid transportation resistance and effectively reduce long-term operating energy consumption.   (3) Corrosion resistance and anti-scaling properties: Because the inner lining ceramic layer is made of (α-Al2O3)，it has excellent resistance to corrosive media such as acids, alkalis, and salt spray, and can withstand various chemical erosions. Its inner surface is smooth and highly inert, resulting in small liquid flow resistance and effectively preventing the adhesion and deposition of scale and impurities, significantly reducing the scaling rate.   (4) Excellent thermal resistance and heat shock resistance: Because the alumina ceramic (α-Al2O3) maintains a single and stable crystalline structure, the ceramic-lined composite steel pipe can operate normally within a temperature range of -50 to 900℃ for an extended period. The material's coefficient of linear expansion is 6-8 x 10-6/℃, approximately half that of steel pipes. Therefore, corundum ceramic has excellent thermal stability.   (5) Low engineering cost: The ceramic lined composite steel pipe is lightweight and cost-effective, being 50% lighter than cast stone pipes and 20-30% lighter than wear-resistant alloy pipes of the same inner diameter. Due to their wear resistance, corrosion resistance, and long service life, they can significantly reduce costs for supports, handling, installation, and operation.   (6) Easy installation and construction: The ceramic lined composite steel pipe is lightweight with good welding performance, and can be installed by welding, flange, or quick connectors, making construction convenient.   Product Applications   This product can replace stainless steel pipes, titanium pipes, high-chromium cast iron pipes, fiberglass pipes, chemical ceramic pipes, cast stone pipes, etc. It is widely used in mining, chemical, petroleum, metallurgy, power, and geothermal energy industries.   This product possesses ultra-hard wear resistance, suitable for use in mining backfilling, ore powder transportation, blast furnace coal injection, coal slurry transportation, and thermal power hydraulic ash removal pipeline manufacturing. It is non-polluting and does not adhere to molten aluminum, making it applicable for manufacturing solution equipment and tools, molten aluminum flow channels and conveying pipes, as well as aluminum low-pressure casting pouring pipes.   Wet conveying is commonly employed in coal washery and long-distance pipeline transportation. The demand for wear-resistant and corrosion-resistant conveying pipes is high. The use of these pipes can create durable conveying pipelines, offering significant economic benefits.
