Highlight:
Wear Resistant Ceramic Sleeve for Steel Pipe with Alumina Ceramic Ring Lining
Product Description
A wear-resistant ceramic sleeve is designed to protect steel pipelines used in abrasive material conveying systems. The sleeve adopts high-hardness alumina ceramic rings installed inside a steel pipe, forming a durable ceramic-lined structure that effectively prevents rapid wear.
The outer pipe can be manufactured from carbon steel or stainless steel, depending on working conditions. Carbon steel is suitable for general bulk material conveying, while stainless steel is recommended for corrosive or high-humidity environments.
The ceramic lining handles abrasion, while the steel shell provides structural strength. This ceramic-lined steel pipe is widely used in pneumatic conveying systems and high-wear pipeline sections.
