01 — Project journey

From requirement to industrial reality.

A documented view of the decisive engineering, manufacturing and validation steps.

Stage 01Engineering evidence

Geometry, materials & analysis domain

Preparation of a local model of the valve body, insert and bolting. Properties are assigned separately to the B1J-V body and the 34CrNiMo6-6 insert at the study temperature.
