Selected Raw Materials：Our tubes are manufactured from specially selected mother pipes, controlled lower content of sulfur levels to promote reliable, consistent welding.
Chemically And Ultra High Purity/UHP Cleaned: Our tubes are chemically cleaned and passivated to keep nonvolatile residue levels to comply with ASTM G93 or SEMI E 49.6. UHP tubes &pipes are rinsed with 18MΩ cm2 DI hot water and purged with 99.9995% filtered nitrogen and are packed in an class 10 clean room.
Traceability and Clean Packaging: Each tube is marked to identify manufacturer, material type and heat code. BA&EP grade tubes & pipes are packed as following manner: ends are faced and protected with polyamide nylon film and polyethylene caps, packed in single (BA grade) or double (EP grade) polyethylene bags.
Professional Inspection Equipment: We have a variety of professional inspection equipment: Scanning Electron Microscope（SEM）,Energy Dispersive Spectroscopy（EDS）, Surface Roughness Gauge, Particle Counter, Micro Vickers, Moisture Analyzer, Metallographic Microscope, Tensile Testing Machine etc.
