Main Inspection Items for Graphite Electrode
1. Quantity & Dimension Inspection
Count finished graphite electrodes against order quantity; Measure overall length, outer diameter, hole depth and tolerance strictly as per technical drawings.
2. Weight Verification
Check single electrode net weight with calibrated weighing equipment; Verify weight consistency to prevent material shortage.
3. Visual Surface Appearance Check
Inspect surface cracks, pores, chipping, dents, scratches, foreign impurities; Check end face flatness; Reject products with severe graphite block defects.
4. Thread & Nipple Matching Test (Critical Item)
Inspect internal thread integrity, no broken teeth or deformation; Carry out screw matching test between electrode and nipples to guarantee smooth assembly on site.
5. Physical & Label Marking Audit
Check product grade marking (HP, UHP, RP graphite electrode), batch number, specification printing; Verify customer required logos and identification codes.
6. Packaging & Protection Inspection
Check end cap protection, plastic wrapping, wooden pallet fixing; Inspect rainproof measures for sea transportation; Verify outer shipping marks.
