Tube carré sans soudure en titane

Titanium square pipe, is a name for square pipe and rectangular pipe, that is, the side length is equal and not equal titanium pipe.It is made of titanium through technological processing.In general, titanium is unpacked, flattened, crimped, welded into a round tube, which is rolled into a square tube and then cut to the required length.Square tubes can be made into straight seam square tubes and seamless square tubes. When the temperature is not higher than 540℃, the oxide film of the titanium square tube will not become thick. However, at higher heat treatment temperature, the oxidation rate of the oxide film will accelerate, and the inner diffusion layer of the oxide film will become a layer of pollution.Oxygen contamination layer has a higher brittleness ratio, which leads to cracks and damage on the surface of parts.Removal of oxygen pollution layer includes mechanical processing, pickling, chemical grinding and other methods.During heat treatment, the heating time should be shortened as far as possible under the premise of protective heat treatment.It can also be carried out in vacuum furnaces or inert gas furnaces. Pollution caused by heating of titanium square pipe fittings in air furnaces should be avoided or appropriately reduced.

Titanium Tubes / Titanium Pipes.
The density of titanium is 4.506-4.516g/cm^3, melting point is 1668, boiling point is 3535. Therefore Titanium have low weight, excellent high strength and nonmagnetic festures, low density, excellent corrosion resistance features, high specificate strength and high temperature resistance features, so it is widely used in chemical industry field, medical field, electronics manufacture, mechanical parts field, automobile industry, and aerospace field, etc.

Titanium Tubes Production Process:
A method for producing and processing titanium tubes, the processing method is as follows: 
Step 1: Forging the titanium ingot into a tube blank, and performing surface treatment on the tube blank; 
Step 2: After the surface treatment, the tube blank is rolled into a titanium tube for the first time, and the oil is removed after the first rolling; 
Step 3: Carry out the first pickling
after degreasing, wash the titanium tube after pickling, dry it after washing, annealing after drying, and straighten the titanium tube after annealing; 
Step 4: Pickling the titanium tube again. After the pickling, rinse the titanium tube, dry the titanium tube
after washing, and then roll the titanium tube for the second time after drying. The rolled titanium tube The finished product is degreasing, pickling after degreasing, washing the titanium tube after pickling, washing and drying, annealing after drying, and straightening the titanium tube after annealing; 
Step 5: Pickling the titanium tube after straightening, repeat the above steps, and obtain the finished product after six times of rolling.
