Introduction

 

Niobium tube is a kind of pipe used for conveying and transferring materials under special conditions, such as high temperature and high pressure, which is widely used in the nuclear industry, aerospace, shipbuilding, chemical industry, and electronics. Due to niobium's excellent corrosion resistance and high temperature stability, niobium tubes have strong compressive, tensile, fatigue, and heat resistance characteristics, so they are widely used in various high-end fields.

Surface treatment

 

 

The surface treatment of niobium tube usually includes mechanical polishing, electrolytic polishing, pickling and sandblasting. Mechanical polishing and electrolytic polishing can improve the surface finish and flatness of the niobium tube, and improve the corrosion resistance of the niobium tube. Pickling and sand blasting can remove impurities such as oil and oxide on the surface of the niobium tube to ensure the cleanliness and flatness of the surface of the niobium tube.
