Hengke supplies alloy steel investment castings for oilfield pump valves and seats. Casting, specified heat treatment and finish machining are coordinated around the approved component drawing, service environment and dimensional or hardness acceptance requirements.
Review sealing profiles, contact surfaces, heat-treatment requirements and machining allowance before tooling. Material, hardness and dimensional acceptance must be tied to the approved valve or seat drawing; pump pressure ratings are verified by the complete assembly manufacturer.
Available verification includes material documentation, dimensional reports and surface examination. Hardness checks, nondestructive testing or component-specific inspection can be agreed against the approved drawing and purchase specification.
