High-resolution proof. Every project documented with materials, processes, tolerances, and QA deliverables.
Tight tolerance threading combined with specific material hardness requirements (28-32 HRC Q&T) for sour service application. Required coordination of heat treat and machining to hit both hardness and dimensional targets.
±0.001" on bore, ±0.0002" on thread pitch diameter
View related service →Inconel 625 is notoriously difficult to machine — high tool wear, work hardening, and tight surface finish requirements on the sealing faces. Required specialized tooling and machining parameters.
±0.0002" on seating surfaces, 8 Ra surface finish
View related service →Complex internal flow paths requiring precise deep hole drilling intersections. All cross-drilled passages had to be deburred and verified leak-free to 10,000 PSI.
±0.001" on port locations, ±0.002" on mounting pattern
View related service →Stellite overlay required precise pre-heat and inter-pass temperature control to prevent cracking. Post-weld machining to tight seat angles with overlay hardness verification at multiple points.
±0.001" on seat angle, minimum 1.5mm overlay thickness
