Hy-Chrome Sleeved Liner has been engineered to overcome the specific stresses that this part encounters in drilling operations.

Conventional liners have a decreasing hardness gradient from the bore. On the other hand, offers a bimetallic supreme sleeved liner. It is an assembly of liner shell with liner sleeve. The liner shell is centrifugally cast and heat treated to withstand hoop stresses generated in shrink fitting and stress reversals during operation.

Construction: The liner sleeve is of high chromium alloyed martensitic white iron and thin walled seamless tube. Special heat treatment ensures proper carbide grain formation, refined microstructure and controlled gain size. Liner sleeves, therefore, offer the maximum possible wear and corrosion resistance. Liner sleeves are through hardened to provide a uniform hardened wear surface throughout the useful life of the liner. The sleeve bore hardness is 60 to 67 Rockwell C scales while the hull has high tensile strength of more than 90000 psi. Uniform wear resistance increases service life – and reduces frequency of liner changes.

The liner is manufactured to tolerances confirming than API Spec-7K. The result is a perfect fit between:-

Liners Sizes: Hy-chrome liners are available from 5” – 6” in increments of ½” and from 6” – 7” in increments of ¼”.
