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. Through the combination of centrifugal force and chemical reactions, a continuous and complete ceramic lining is formed within 90°, 45°, and other curved metal shells. The ceramic layer at the curved sections has uniform thickness with no splicing gaps. Compared to straight pipes that only need to withstand axial erosion, elbows must handle local high-velocity impact when the medium changes direction. Therefore, the ceramic lining in the curved section adopts a gradient structure design for superior impact resistance. It is suitable for pipeline turning points, solving the overall failure problem of traditional elbows caused by rapid local wear. When used with straight pipes of the same material, it can form a comprehensive wear-resistant protection system. 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.

Q
In mining development, which type of wear-resistant pipe offers a better balance between functional adaptability and economy for long-distance transportation of media such as mineral concentrate and slurry?
A
SHS ceramic lined composite steel pipe exhibit high hardness and excellent wear resistance. The smooth surface of the ceramic lining, with its low roughness, reduces frictional resistance during media transport, effectively resisting wear caused by particle erosion and reducing energy consumption. In long-distance transport, it can reduce the load on pumps and save operating costs, making it a superior choice for long-distance media transport.
Q
The oil industry deals with high-pressure transportation of sand-containing crude oil, and the sand particles are abrasive. From the perspective of compression resistance and wear resistance, which material would be more suitable?
A
High-pressure crude oil transportation containing sand requires a balance between pressure resistance and wear resistance. SHS ceramic lined composite steel pipe offer good wear resistance but are brittle and prone to cracking under high pressure, with only moderate pressure resistance. Hard ceramic patch composite steel pipe have good wear resistance, but the bonding strength of the laminations may be affected under high pressure, posing a risk of detachment. Bimetallic composite steel pipe have a strong base steel pipe with high pressure resistance, and the wear-resistant alloy layer addresses sand abrasion. Their overall performance is well-suited to high-pressure conditions; although more expensive, they guarantee stability under high-pressure conditions. Therefore, Bimetallic composite steel pipe remain the more suitable choice.
Q
In the chemical industry, when transporting corrosive acid and alkaline solutions, which material is more suitable—considering both corrosion resistance and wear resistance reliability?
A
The core advantage of SHS ceramic lined composite steel pipe lies in the chemical stability of the ceramic lining, exhibiting extremely strong corrosion resistance to acid and alkali solutions and effectively resisting the erosion of hydrogen ions and hydroxyl ions. Simultaneously, the high hardness of ceramic provides good resistance to wear from small amounts of solid particles in solutions. In scenarios with few solid particles and moderate impact, SHS ceramic lined composite steel pipe offer the best cost-performance ratio.
Q
Adaptability to metallurgical high-temperature dust scenarios (temperature >300°C)?
A
Ceramic patch tube + external insulation layer.
Alumina ceramics can withstand temperatures up to 800℃, but the steel pipe body needs to be protected against high-temperature deformation;
SHS ceramic lined are prone to cracking at high temperatures due to differences in their coefficients of thermal expansion.
In bimetallic tubes, the hardness of high-chromium cast iron decreases by 50% at temperatures above 400℃, and its wear resistance drops sharply.
