SHS ceramic lined composite steel straight pipe

SHS(Self-Propagating High-Temperature Synthesis) ceramic lined composite steel straight pipe utilize self-propagating high-temperature synthesis centrifugal technology. The inner layer of corundum ceramic (α-Al2O3) has a Mohs hardness of 9.0, with wear resistance exceeding ordinary steel pipes by 20 times, making it an ideal choice for long-distance transportation. It can withstand continuous erosion from materials during long-distance conveying, significantly extending the pipeline's service life.   Its inner surface is smooth with minimal fluid resistance, reducing energy consumption during long-distance transportation. It combines the strength of steel pipes with the corrosion resistance of ceramics, operating stably between -50°C and 900°C, making it suitable for conveying various materials. Weighing only half of traditional wear-resistant pipes, it is particularly ideal for long-distance transportation of powders and slurries in mining, power generation, and other fields, offering outstanding comprehensive benefits.   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.

SHS ceramic lined composite steel elbow pipe

SHS ceramic lined composite steel elbow pipe are special-shaped pipe fittings manufactured using self-propagating high-temperature synthesis centrifugal technology.

Ultra-high molecular weight polyethylene(UHMWPE) lined steel pipe

Ultra-high molecular weight polyethylene composite pipe is made by scientifically bonding ultra-high molecular weight polyethylene pipe and carbon steel pipe. Its characteristic is that the outer layer is a steel pipe with flanges as the reinforcing sheath, and the inner layer is coated with UHMW-PE as the matrix pipe material, combining the two characteristics into one.   We adopt an innovative "adhesive-free interference fit composite" process. Specifically, the outer diameter of the ultra-high molecular weight polyethylene (UHMWPE) lining pipe is designed to be larger than the inner diameter of the steel pipe. Then, mechanical diameter reduction is applied to shrink the diameter of the UHMWPE pipe, which is subsequently inserted into the steel pipe. No adhesive is required-leveraging the exceptional shape memory property of UHMWPE, the UHMWPE lining pipe will firmly adhere to the inner wall of the steel pipe after being left to stand for 24 to 48 hours.   This interference fit composite technology has not only been applied in the existing field of high-pressure slurry transportation in mines, but also in oil fields-specifically for oil production wells that suffer from severe friction and serious wax deposition. By leveraging the properties of ultra-high molecular weight polyethylene (UHMWPE), such as high wear resistance, high corrosion resistance, high impact resistance, self-cleaning, and self-lubrication, and through this advanced steel tight-lining interference fit composite process, the service life of oil production pipes has been significantly extended. Currently, this technology has been widely used in the two major domestic oil fields.

Dense-phase stabilizer

The dense-phase stabilizer is a key equipment for optimizing dense-phase pneumatic conveying systems. Composed of one-way valves, filters, restrictors, and fluidization pipes, it is installed at multiple points along the conveying pipeline. It is mainly used to stabilize the flow state of high-concentration powdery and granular materials during the conveying process.   During operation, relying on its unique internal structure—such as specially designed flow deflectors and buffer chambers—it can effectively regulate the gas-solid mixture ratio, enabling materials to be conveyed in the form of more uniform and stable plug flow or low-velocity dense-phase flow. This significantly reduces the risk of material blockage in the pipeline, minimizes wear, and extends the service life of the pipeline. Furthermore, its materials are mostly wear-resistant and corrosion-resistant steel or ceramic-lined materials, which can adapt to complex and harsh working conditions, ensuring the efficient and stable operation of the conveying system while reducing enterprises’ maintenance costs and energy consumption.
