Titanium – the ideal material for the chemical industry

Titanium is extensively utilized in numerous industries due to its exceptional mechanical qualities and resistance to corrosion. Titanium is a corrosion-resistant material that can replace stainless steel, particularly in chemical applications. This is important because it can prolong the life of equipment, save costs, prevent pollution, and improve productivity. Titanium is one of the primary anti-corrosion materials used in chemical equipment. As a kind of corrosion-resistant structural material used in chemical equipment, titanium has become an ideal material in chemical equipment.


1. Main application of titanium in chemical industry

  • Chlor-Alkali industry

    The chlor-alkali business was one of the first use of titanium in the chemical industry. These include the manufacturing of bleaching powder, oxychloride, chlorine gas, pesticides. Titanium equipment and pipes account for almost a quarter of its total mass volume. It is utilized, for instance, in the following applications: refined brine preheater, vacuum dechlorination pump and valve, wet chlorine cooler, chlorine wastewater dechlorination tower, ionic membrane electrolyzer and anode liquid pump, etc.

  • Petrochemical Fiber

    Currently, titanium equipment is utilized by businesses that design and manufacture polyester, nylon, Vinylon, and other petroleum-based chemical fibre. The development of chemical fibre production has benefited greatly from the use of titanium equipment, particularly in the areas of safe and stable continuous production, product quality improvement, preventing premature corrosion failure of stainless steel, equipment service life extension, reduced parking and maintenance costs, and overall economic benefits.

  • Fine Chemical Engineering

    The industrial raw material from propylene oxide plants has a high corrosive power. Liquid chlorine and propylene are the two main raw materials used in PO production. These potent corrosives established the corrosion foundation for the PO production equipment pipeline. In these conditions, metals like carbon steel, Al, Cu, Ni, and stainless steel, as well as other metals, cannot withstand corrosion, titanium is the ideal corrosion-resistant metal material.

  • Soda ash industry

    Titanium is mostly used in crystallizing external coolers, ammonia condensers at the top of distillation towers, ammonium chloride mother liquid heaters, plate heat exchangers, umbrella plate heat exchangers, Carbonizing tower cooling pipe, carbon dioxide turbine compressor rotor impeller, lalkali pump, and other processes related to the production of soda ash.

  • Other Industries

          Titanium dioxide – titanium is used in film concentrator, calcining kiln feed pipe, centrifugal distribution plate, etc.   

         Urea–Titanium is used in urea synthesis tower lining, ammonia stripping tower, general decomposition tower heater, methylamine pump inlet, discharge valve and spring, high pressure mixer.

        Dyestuff – titanium for coil heat exchanger, absorption tower, purification tower nozzle, fan, water ring vacuum pump, filter and so on.

       Nitric acid – Titanium is used in nitric acid evaporators, nitrous oxide exhaust preheaters, nitric acid steam preheaters, gas scrubbers, quick coolers, condensers, turbine blowers, pumps, valves, pipelines, etc.

2. Properties of titanium alloys

  • The lower density — It can significantly reduce string load, especially in ultra-deep oil Wells.

  • The higher strength–It includes elongation strength, creep strength, fatigue strength, etc
  • Excellent corrosion resistance– Excellent seawater corrosion resistance.
  • Large elastic deformation capacity–the yield strength of titanium alloy is high and elastic modulus (E) is low, so it is very suitable for spring, more importantly, it is suitable for large displacement horizontal Wells.

  • Low coefficient of expansion–This feature makes petroleum equipment more adaptable to temperature changes and reduces the internal stress of structural components.

  • Non-magnetic–It is suitable for the normal use of some detection, communication and control means in various equipment.

Titanium alloy pipes, flanges, bolt fittings, and other equipment are presently being utilised more widely in the petroleum industry, and as various titanium processes and technologies develop, various titanium alloy oil sleeves and other equipment will become more generally employed.
