Strength and Application of Titanium Coil Tube

Titanium coiled tubing because titanium metal for many media have better than steel, its corrosion resistance, heat strength, low temperature toughness and fracture toughness are also better than steel. Titanium density of 4.51g/cm3, higher than aluminum and lower than steel, copper, nickel, than the strength is located in the first metal. (Note: Specific strength = strength and density ratio), so it is mainly used as a variety of container heating and cooling.

Classification of titanium coil:
Titanium coil, titanium serpentine coil, titanium U-shaped coil, titanium double coil, titanium tube heat exchanger, titanium double jacket coil, U-shaped titanium coil, titanium U-shaped heat exchanger, titanium tube heat exchanger, titanium tube heat exchanger, suspended titanium coil, double inlet and double outlet single-layer titanium coil, single-layer titanium coil, double-layer titanium coil, triple-layer titanium coil, quadruple-layer titanium coil, and five-layer titanium coil.

Fixing method of titanium coiled tube
1. detachable;
2. non-removable.
Mainly according to the medium of different materials and the degree of corrosion on the titanium coiler to decide which fixing method to use. In general, the main detachable way is mainly to facilitate the use of the process of routine maintenance, overhaul, cleaning and so on.

Application scope of titanium coiler
Titanium coils are widely used in chemical industry, petroleum, metallurgy, power generation, seawater desalination, chlor-alkali, salt production, titanium coils are also used in the production of titanium dioxide, glycine, nitro-aminophenol, pesticides, fuel chemicals, pesticide intermediates, cyanuric acid, dichlorocyanuric acid, trichlorocyanuric acid and other industries.

Of course, in general, titanium is corrosion-resistant in oxidizing, neutral and weakly reducing media, because titanium and oxygen-containing media will react to the surface to generate a layer of tight, inert, strong adhesion, the oxide film, to protect itself from corrosion. Even by mechanical wear and tear will soon be self-healing or regeneration. In summary, titanium is a metal with a strong passivation tendency.

Medium temperature below 315 ℃ titanium oxide film always maintain this characteristic.

The progress and development of science and technology, new materials made of a variety of equipment is also a large number of applications in the petroleum, chemical, aerospace, medical and other industries, and then derived from different, for the production of sulfuric acid, hydrochloric acid, methylamine solution, high-temperature wet chlorine and high-temperature chloride and other production of metal in the new needs, the development of titanium - molybdenum, titanium - palladium, titanium - molybdenum - nickel and a series of corrosion-resistant titanium alloys. Titanium alloys can be used for a long time at temperatures of ≥600℃.

Although the thermal conductivity of titanium is lower than carbon steel, copper and other metals, but because of its excellent corrosion resistance, so the wall thickness can be reduced, and the surface of the heat transfer with the steam for the drip condensation, the surface does not scale, greatly reducing the thermal resistance, so that titanium's heat transfer performance is more excellent.
