1.Liners combine the strength of a forged steel outer shell with the abrasion and corrosion reisistance of a high chromium iron inner sleeve.

2.Feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minmum uniform bore hardness of HRC65

3. The surface of the liners with a mirror-like smooth finish and the inner holes’ dimension tolerance is strictly controlled to ensure a long using life of more than 800 hours.

4. Our liner made for superior performance under tough corrosive and abrasive conditions.
