What is Aluminium Pipe ?

Aluminium pipe is a registered trademark (of Special Metals Corporation) referring to a family of austenitic nickel-chromium super alloys, Aluminium seamless pipe is typically used in applications where high temperatures are present due to a thick, stable passivating oxide layer which is formed. Inconel® is a nickel-based alloy with superior corrosion resistance and temperature performance to stainless steel. SCH40 Aluminium pipe is a material that is specifically optimized for some of the toughest use conditions. Aluminium welded pipe alloys or superalloys are nickel-based alloys that exhibit traits such as high resistance to corrosion, oxidation, carburization, pitting, crevice, corrosion cracking, and high temperature strength. Aluminium clad pipe are generally known for their resistance to oxidation and ability to maintain their structural integrity in high temperature atmospheres.

Aluminium alloy pipes are nickel-chromium alloys which can be usable in different welding processes. This Aluminium pipe used in high heat tolerance Environment. Welding of Aluminium pipe would be difficult because the welds have the tendency to crack.
