To take or not to take, that’s question — it is unlikely to be appropriate when buying titanium pipe, it has such exceptional qualities.
Titanium pipe at request of customer can have any section and length. Its technical qualities will be determined by chemical composition of material (standardized by GOST 24 231−80) and production method. According to production method, titanium pipe is: 1) hot rolled, undergoes mechanical processing on outer and inner surfaces; 2) cold rolled seamless; 3) welded from titanium of grades VT1−0 and OT4−0. Chemical composition of welded pipes is standardized by GOST 19 807−74, and production — GOST 24 890−81. Basis of welded pipes is tape welded by argon-arc or other means. Cold-deformed seamless pipes are produced according to OST 1 90 050−72, GOST 22 897−86, from titanium VT1−0 or alloy PT-7M with chemical composition according to GOST 19 807−74. Surface of pipes may be ground or etched. In marking of alloys, letters inform developer (for example, PT — alloys developed by CRI KM «Prometey», VT — VIAM-titanium), numbers indicate corresponding serial number of alloy.
According to quality level, pipe is divided into group A with etched surface in annealed state and group B without surface etching and heat treatment. Surface of pipes should not have delamination, cracks, shells, deep scratches, weld defects. Traces of broaches are allowed. Ends are deburred and evenly cut at right angles.
Titanium pipe is characterized by high strength, corrosion resistance and lightness. It has satisfactory machinability, good ductility and weldability, fully retains its advantages in conditions of extremely high and low temperatures. It is reliable in all atmospheric conditions, in moist soil, sea and chlorinated water. Corrosion rate is less than 0.002 mm/year. Remarkable stability in atmosphere of sulfur, chlorine, chlorine oxide, in nitric acid at elevated temperatures. Titanium is resistant in environment of petroleum products, in mixture of caustic potassium and sodium at concentration of up to 40%, in boiling solutions of 20% NH3 OH, in environment of molten sulfur up to 240 °C, in atmosphere of industrial gases and СО2, in aqueous solutions of H2 S and sulfate salts caustic soda. At t° to 100 °C, titanium is stable in acetic anhydride organic acids, in fresh water up to 260 °C and pressure of 130−140 atm.

Due to its exceptional qualities, titanium pipe has found widest application today — in production of jet technology, underwater shipbuilding, petrochemicals. It is used in well drilling, oil and gas production and copes with lot of complex tasks, excessive alloys from other metals. Mark V. T. — light and durable, resistant to corrosion and chemical agents. Most often used in gas and oil production, deepwater exploration, in development of offshore fields. Pipe grade VT1−0 is produced cold and hot rolled. After rolling, it undergoes mechanical processing. It is resistant to aggressive environments and temperature extremes from -250 °С to + 450 °C, which is important in chemical industry. Non-magnetism and significant electrical resistance make it popular in radio electronics. Mark O. T. is used less often, it is also not much exposed to moisture, salts and temperature changes, it is used in petrochemistry and gas processing.
