This coating provides a tight metallurgical bond, combining the strength of steel with the corrosion and heat resistance of aluminum. The pipe is manufactured to GB/T18592-2001, a standard that ensures consistent quality for industrial applications.
The diffusion layer in the calorized pipe is a mixture of iron and aluminides, with aluminum content ranging from 30 to 45 wt.% at the surface, decreasing toward the substrate. This structure delivers high temperature resistance, typically up to 600°C, and enhances wear resistance in demanding environments. The process involves heating components in a powder mixture containing aluminum, a halide, and an inert diluent, followed by slow cooling to ensure a uniform coating.
Industries such as chemical, petrochemical, and power generation use these pipes for heat exchangers, furnace components, and thermal processing equipment. The calorizing process increases the lifespan of lance pipes by five to seven times compared to mild steel in oxygen injection applications, reducing consumption rates and operational costs. Buyers can source these pipes in various sizes to match their specific requirements, with bulk pricing available for international trade.

Before placing an order, verify the pipe’s compliance with GB/T18592-2001 and request documentation confirming the aluminum content and metallurgical bond quality. Confirm whether the pipe’s temperature resistance meets your operational requirements, as the 600°C typical limit may vary based on the specific aluminum diffusion process used.
Logistics considerations include packaging to prevent damage to the aluminum coating during transit. Clarify lead times, as production may depend on the supplier’s mill schedules and order volume. Incoterms such as FOB or CIF should be agreed upon, with payment terms typically structured as TT or LC for bulk orders to ensure security for both parties.
Quality checks should focus on the uniformity and thickness of the aluminum diffusion layer, as these directly impact the pipe’s performance. Request material test certificates (MTCs) for the base steel and coating, and consider third-party inspections for large orders. Inspect for any signs of coating defects, such as cracks or uneven diffusion, which could compromise durability in high-temperature environments.
