90° Elbow Polished Buttweld FAQs

Q 1. What is Stainless Steel Elbow Polishing?

Stainless steel elbow polishing refers to the use of mechanical, chemical or electrochemical effects 

to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. Polishing cannot improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss.

Q 2. What is the Purpose of Polishing for Stainless Steel Buttweld Fittings?

It is not only to make the appearance beautiful but also to reduce the rust phenomenon during use. 

After polishing, the overall use-value of stainless steel butt-welding fittings will be relatively improved, the future service life will be prolonged, and it will be more durable in use.
