SURFACE REQUIREMENTS
Surface of rolled products: No need extra polishing or smooth treatment.
Mill Finish— A finish without additional polishing oroperations intended to smooth the surface.
Mechanical polished surface: Purchasers according the same numbering abrasive (grinding stuff) to polish the products get the required products’ surface:
Finish No. 80 – A ground finish produced by polishing a tube with an abrasive media impregnated with No. 80 grit.
Finish No. 120 – No. 120 grit.
Finish No. 180 – No. 180 grit.
Finish No. 240 – No. 240 grit.
Other mechanically polished finishes may beagreed upon between the purchaser and manufacturer
Electrolytic polishing of the surface: Before this processing, manufacturer could use other ways to polish products.
The maximum average of roughness: Customers could specify the maximum roughness of internal surface, external surface and both surface.
Surface furnishment also could be decided by manufacturer or purchaser.
Normally surface treatment: Internal, External, SF4, SF3, etc.
