Titanium alloy has many applications in petrochemical industry, among which titanium tube, titanium rod and titanium heat exchanger are the most commonly used titanium materials. The application of titanium rod in petrochemical industry is introduced below.

In most inorganic salts, titanium rods are completely inert and have excellent corrosion resistance. For example, in the electrolytic Mn02 production, the electrolyte is neutral MnSO4 solution, which requires the electrode resistance to sulfate corrosion. The telegraph machine made of lead alloy and graphite is not effective. After switching to titanium, the anode is protected from corrosion and becomes a semi-permanent device.

Titanium rods have excellent corrosion resistance in almost all organic acids and organic media except formic acid and oxalic acid. In addition to methanol, titanium also resists the corrosion of organic alcohols, aldehydes and ketones.

Finally, titanium rods are resistant to wet H2S gases, wet SO4 gases, ammonia, and industrial atmospheres (titanium should be used with special care in small H2-containing media and pure oxygen).

For example, in the oil refining industry, equipment is often corroded by H2S, NH8, sulfide and chloride. Titanium equipment can solve the corrosion problem. Titanium is mainly used in distillation tower, condenser, air cooler and other equipment in petroleum refining. In addition, coking production will encounter industrial atmospheric corrosion, this aspect of the application of many examples.
