LIANHE applies in-process and final inspection throughout production:
Inspect raw-material grade, outside diameter, and wall thickness.
Check length and pipe-end condition after cutting.
Inspect socket dimensions and wall thickness after forming.
Check weld dimensions and surface quality where applicable.
Inspect product dimensions after heat treatment.
Verify surface quality after polishing or pickling.
Perform hydraulic-pressure and airtightness tests.
Check product markings, quantities, and packaging before shipment.
Available documents include:
EN 10204 3.1 Material Test Certificate
Raw-Material Inspection Certificate
Dimensional Inspection Report
Hydraulic and Airtightness Test Report
Radiographic Testing Report, when applicable
Third-Party Inspection Report
