Grade, heat / lot identification and required material test results.
QUALITY SYSTEM
Quality through
the manufacturing process.
Raw material inspection, in-process control and final checks for precision tube applications.
QUALITY POLICY
Material testing.
Process control.
Final inspection.
Inspection connects the material, manufacturing process and finished tube to the component requirement.
01
Chemical composition and material properties.
Raw material inspection
Material identification, chemical analysis, tensile testing, hardness testing and metallographic examination support the inspection plan. Heat and lot references connect material to the recorded test results.
02
Control the tube as it is made.
In-process inspection
Laser diameter measurement, roundness, surface roughness and contour measurement support dimensional and surface requirements. Eddy current and ultrasonic inspection are selected within the specified inspection plan.
03
Check the component before the next operation.
Final inspection & finishing
Length, runout, end condition and appearance are checked as specified for the part. Cleaning and rust-preventive oiling form part of the specified finishing route.
