The outer hull, or body, of the liner is a high strength forging. SSH uses forgings exclusively to ensure the consistent quality. The sleeve is centrifugally cast in the SSH facilities by skilled craftsmen. It has the maximum amount of chrome for the base metal and SSH adds molybdenum to increase the hardness depth. The sleeve is then inserted into the hull at a tightness that exceeds its counterparts. The liner is rated to match the pressure rating of the pump per liner size.
• Rated for all drilling operations up to 5,000 PSI and 7500 PSI.
