To take or not take, that is the question — is unlikely to be appropriate when buying a titanium tube, so it possess exceptional qualities.
Titanium pipe on request can have any cross-section and length. Its technical qualities are determined by the chemical composition of the material (24 normalizes GOST 231−80), and the mode of production. By way of production of titanium tube is: 1) Hot passes machined on the outer and inner surface, 2) cold-rolled seamless and 3) welded titanium grades and VT1−0 OT4−0. Chemical composition of welded pipes GOST 19 807−74 normalized, and production. — 24 GOST 890−81. The basis of welded pipe tape is used, argon-arc welded or otherwise. Cold-seamless pipe produced according to OST 1 90 050−72, GOST 897−86 22, titanium VT1−0 or PT-7M alloy with the chemical. composition 19 according to GOST 807−74. The surface of the tubes can be polished or etched. The marking of alloy letter informing about the developer (eg, PT — alloys, developed by CRI «Prometheus», BT — VIAM-titanium), the figures indicate corresponding serial number of the alloy.
The level of quality pipe is divided into a group A with the etched surface in the annealed condition and group B, without heat treatment and etching. The surface of the pipe should not have bundles, cracks, sinks, deep scratches, imperfections. Admitted sledі broach. The ends are cleared of burrs and sharp cut off at a right angle.
titanium pipe high strength is different, corrosion resistance and ease. It has satisfactory processability, good ductility and weldability, fully retains its dignity in the face of very high and low temperatures. It is reliable in all weather conditions, in wet soil, sea and chlorinated water. The corrosion rate in this case is less than 0.002 mm / year. Remarkable stability in the atmosphere of sulfur, chlorine, chlorine oxides in nitric acid at elevated temperatures. Titanium racks among petroleum products, a mixture of potassium hydroxide and sodium at a concentration of 40%, a boiling solution of 20% NH 3 OH, in the molten sulfur medium up to 240 ° C, in an atmosphere of industrial gases, and SO 2, into H 2 S aqueous solution and sulfates, caustic soda. At t ° to 100 ° C titanium is resistant to acetic anhydride of organic acids, in fresh water up to 260 ° C and a pressure of 130−140 atm.

Thanks to the exceptional qualities of titanium pipe is found today the most widely used — in the production of jet technology, underwater shipbuilding, petrochemicals. It is used in drilling wells, oil and gas, and copes with weight challenges unbearable alloys of other metals. Brand VT — lightweight and durable, resistant to corrosion and chemicals. Most often used in gas and oil production. deep-sea exploration, the development of offshore fields. VT1−0 brand pipe produced cold- and hot-rolled. After rolling, it passes machining. It is resistant to aggressive environments and temperature extremes from -250 ° C to + 450 ° C, which is important in the chemical industry. Nonmagnetic and a significant electrical resistance make it popular in radioelektrotehnike. Mark OT is used less frequently, it is also a little exposed to moisture, salt and temperature differences, used in the petrochemical and gas processing.
