Application of Titanium Ti-6AL-4V(Grade 5) alloy rod in petroleum refining industry!
In most inorganic salts, Titanium Ti-6AL-4V alloy rod is completely inert and has excellent corrosion resistance. For example, in the production of electrolytic Mn02, the electrolyte is neutral MnSO4 solution, the electrode is required to resist sulfate corrosion, leaving lead alloy and graphite made of telegraph, the effect is not good.
Titanium Grade 5 alloy rod has excellent corrosion resistance in almost all organic acids and organic media (except formic acid and oxalic acid). In addition to methanol, titanium is also corrosion resistant to organic alcohols, aldehydes and ketones. In the petrochemical industry, for example, acetaldehyde is used to make acetic acid. Because acetic acid, acetaldehyde, chloride and catalyst corroded stainless steel equipment seriously, titanium material was used to solve the corrosion problem in acetic acid production. For example, with propylene acetone, can also use titanium production equipment, Japan completed an annual output of thirty thousand tons of acetone factory, with titanium nearly forty tons.
Finally, Titanium Ti-6AL-4V(Grade 5) alloy rod is corrosion-resistant to wet H2S gas, wet SO4 gas, ammonia and industrial atmosphere (it is especially prudent to use titanium in small hydrogen-containing media and pure oxygen). For example, in the oil refining industry, equipment is mostly corroded by H2S, NH8, sulfide and chloride, and the use of titanium equipment can solve the corrosion problem. Titanium in petroleum refining, mainly used in distillation tower, condenser, air cooler and other equipment. Titanium is an ideal corrosion resistant material in the production of synthetic ammonia and urea. In addition, the industrial atmospheric corrosion problem will be encountered in coking production, and there are many examples of its use.
