Eddy-current testing

Passivating bath immersion

Non-destructive in-line inspection probes examine 100 percent of longitudinal weld seams, flagging microscopic subsurface voids and wall thickness variations before cutoff.

Rotary gang shear blades process parent master coils into narrow strip widths held within tight dimensional tolerances across Grade 304 and 316 alloys.

Progressive multi-stand roller banks shape calibrated flat strip into structural profiles, fused via automated high-frequency induction and orbital TIG weld heads.

Submerged acid pickling tanks cleanse residual heat tint from internal and external surfaces, restoring the passive chromium-oxide corrosion barrier across every length.

Metallurgical Verification

In-house spectral and mechanical analysis

Our Estate Avenue testing laboratory subjects every production heat to optical emission spectrometry, quantifying nickel, chromium, and molybdenum fractions against mill certification thresholds. We verify alloy composition before bundles clear dispatch.

Hydraulic test frames execute destructive tensile pulls and flattening tests alongside hydrostatic pressure validation up to 3,000 PSI, confirming structural integrity for high-pressure industrial transfer systems.
