Direct Reduced Iron (DRI/HBI) conveying is one of the most demanding conditions in the metallurgical industry: material temperatures reach 650–850°C, with hard and sharp-edged particles. Ordinary heat-resistant steel pipes often fail within just three months due to wear-through and air leakage, leading to frequent shutdowns, production losses, and immense operational headaches.
Hisan High-Temperature Overlay Welding Wear-Resistant Pipe is engineered specifically for this challenge. The base pipe is made of high-quality heat-resistant stainless steel (310S), with an inner wall fully automatically overlaid with a Cr-Mo-Nb-W-V multi-component heavy alloy wear-resistant layer. This layer forms a metallurgical bond with the base pipe – it does not peel off or crack under high temperatures, completely eliminating the common problems of ceramic liner detachment and bimetal cast pipe thermal cracking.
Its core advantage lies in exceptional high-temperature wear resistance: remaining hard and tough even under 800°C scorching particle erosion, effectively resisting cutting and gouging wear, while reducing friction and preventing material build-up and blockage.
Proven results speak for themselves: after a Russian customer switched to Hisan products, the conveying line has been running continuously and stably for over 12 months, with the pipe remaining intact and zero shutdowns caused by wear-through – service life significantly extended. Why settle for yearly replacements and monthly repairs when one investment brings long-term peace of mind?
