Niobium Pipe
niobium pipe
Brief introduction:
Niobium is a gray metal and its melting point is 2468 ℃, boiling point is 4742 ℃ , density is 8.57 g / cm3.
Along with the fast development of our national economy, especially the development in aerospace and energy industry, niobium is used widely.

Niobium pipe

has seamless pipe and seamed pipe.
Material:         RO4200-1, RO4210-2
Diameter:      φ1.0-100mm
Thickness: 0.2-5.0mm
Length:   200mm-9000mm
Standard:      As per ASTM B394-98
Purity:            ≧99.9%or 99.95%

Properties of niobium pipe:
Properties of niobium pipe are similar with those of niobium, such as high melting point, good corrosion resistance, compression resistance, abrasion resistance, etc.

Applications of niobium pipe:
Niobium pipe is mainly used as spinning of thin tube blank, thermocouple cannula and other special purposes.

Sanhui Co., Ltd is one of

Chinese manufacturing companies

and we can manufacture niobium pipe according to buyers' special requirements.
