Ceramic liners: DL ceramic liners combine the strength of a forged steel outer shell with the abrasion and corrosion reisistance of a ceramic inner sleeve. We supply Zirconia as well as Alumina sleeves, of which Zirconia performs better impact strength,higher hardness and be honed to finer surface finishes than Alumina.
Liners have Four types: premium chromium liners/ceramic liners/chromium-plated liners/ hardened liners
Premium Liners:made with a high chrome/iron sleeve or bi-metal sleeve into a forged steel hull.
Ceramic Liners:combine the strength of a forged steel outer shell with the abrasion and corrosion resistance of a ceramic inner sleeve.provide zirconia sleeves as well as alumina sleeves.
Chromium-Plated Liners:made from premium forged steel with the core plated by chrome.
Hardened Liners:these liners are hardened and heat treated under strict quality control to a minimum of 60RChardness .Each liner is honed to a mirror-like finish for smooth.
