Our stud welding type ceramic-lined steel pipe is a high-performance composite pipeline, which integrates the superior pressure-bearing capacity of metal pipes and the excellent wear-resistant & high-temperature resistant properties of ceramic materials. Adopting advanced stud welding connection technology, it realizes the firm combination of ceramic liner and metal matrix, effectively solving the problems of ceramic liner falling off and cracking under harsh working conditions. It is an ideal pipeline solution for conveying high-temperature, high-abrasion, and corrosive media in metallurgy, electric power, mining, and building materials industries.
Core Structure
Metal Matrix
Material: Carbon steel, alloy steel (customizable according to customer requirements).
Function: It bears the external pressure and mechanical impact of the pipeline system, provides reliable support for the ceramic liner, and has good welding and installation performance, which is compatible with various industrial pipeline connection modes.
Ceramic Liner
Material: High-purity alumina ceramic, silicon carbide ceramic
Performance: Mohs hardness ≥ 9, temperature resistance up to 1000℃, excellent wear resistance (20-50 times that of ordinary steel pipes), and corrosion resistance, directly contacting the conveying medium to ensure the long-term stable operation of the pipeline.
Stud Welding Connection Layer
Process: Dense metal studs are welded to the inner wall of the metal pipe. After the ceramic liner prefabricated parts are installed, they are combined with the studs through high-temperature sintering and special adhesive bonding, forming a mechanical interlocking structure.
Advantage: The connection strength is greatly improved compared with the traditional adhesive method. The reserved micro expansion gap between the ceramic liner and the metal matrix can offset the thermal expansion and contraction difference under high temperature alternating conditions, preventing ceramic cracking and falling off.
