T2 purple copper tube is a kind of non-ferrous metal tube. It is pressed and drawn seamless tube. The corresponding U.S. grade is C11000, and the Japanese grade is C1100, with good thermal and electrical conductivity, processability, ductility, corrosion resistance and weather resistance. It can be used in chemical industry, HVAC, mechanical equipment, water supply system and other industries with pipes and fittings.
T2 copper pipe characteristics and scope of application: good electrical and thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Containing reduced electrical conductivity, thermal conductivity less impurities, trace amounts of oxygen on the electrical conductivity, thermal conductivity and processing performance does not affect, but easy to cause "hydrogen", not suitable for high temperatures (such as > 370 ° C) in a reducing atmosphere processing (annealing, welding, etc.) and use.
T2 copper tube weight formula, copper is pure copper: pure copper is purple red, also known as copper. The density of pure copper is 8.96, melting point is 1083 ℃, and the weight of copper tubes is calculated as follows.
The mass of copper is calculated as follows: G=8.96πδ(D-δ)/1000
G: mass kg δ: tube wall thickness mm D: tube diameter mm
TP2 and T2 are suitable grades for the manufacture of copper violet tubes.
