All the raw materials will be firstly made pipeline cutting.
It is consisted of a series of bare oil(carbon steel,alloy steel,or
durable heat steel) and header and other auxiliaries.
TubesΦ32,38,42 and so on,also as the request.
With the artistic apperance and accurate size,the advance process
for bending tube and welding,the first rate test equipment and
Corrosion resistance in an extensive range of marine and chemical
environments. From pure water to nonoxidizing mineral acids, salts
This alloy is more resistant to nickel under reducing conditions
and more resistant than copper under oxidizing conditions, it does
show however better resistance to reducing media than oxidizing.
Good mechanical properties from subzero temperatures up to about
Good resistance to sulfuric and hydrofluoric acids. Aeration
however will result in increased corrosion rates. May be used to
handle hydrochloric acid, but the presence of oxidizing salts will
greatly accelerate corrosive attack.
Resistance to neutral, alkaline and acid salts is shown, but poor
resistance is found with oxidizing acid salts such as ferric
Excellent resistance to chloride ion stress corrosion cracking.
