Titanium square tubes are hollow rectangular cross-section thin-walled titanium thin-walled tubes. In addition to thickening the wall thickness of hot-rolled extra-thick-walled tubes, their corner dimensions and edge straightness can reach or even exceed the level of resistance welded cold-formed square tubes. It has good comprehensive mechanical properties, good weldability, cold and hot processing properties and corrosion resistance, and good low-temperature toughness.
High Quality Titanium Square Tube details
The square pipe is a hollow rectangular thin-wall titanium thin-wall pipe with a rectangular section. In addition to the thickening of the wall, the corner size and the flatness of the side of the extra-thick hot rolled pipe can reach or even exceed the level of the resistance welding cold-formed square pipe. Good comprehensive mechanical properties, weldability, cold, and hot working properties and corrosion resistance, low-temperature toughness
The Process Of Titanium Square Tube
Step 1: The titanium ingot is forged into a tube blank, and the surface of the tube blank is treated;
Step 2: The surface-treated tube blank is rolled into a titanium tube for the first time, and the oil is removed after the first rolling;
Step 3: The first pickling is carried out after oil removal. After pickling, the titanium tube is rinsed. After rinsing, the tube is dried.
Step 4: pickling the titanium tube again, after pickling, wash the titanium tube, and wash the titanium tube after drying, after drying the titanium tube for the second time rolling, the rolled titanium tube finished products for oil removal, oil removal after pickling, pickling after washing the titanium tube, wash after drying, drying after annealing, annealing after straightening the titanium tube;
Step 5: After straightening, and pickling the titanium tube, repeat the above steps, and get the finished product after six times rolling.
Why Wash And Dry Titanium Tubes After Pickling?
After pickling the titanium tube in an acid solution, although the purpose of removing the oxide layer has been achieved, the surface of the titanium tube is more or less eroded by acid. If this residual acid is not removed, a part of the hydrogen will be diffused into the matrix of the titanium tube due to the chemical action of residual acid, and the ductility of the titanium tube will be reduced. At the same time, the residual acid on the surface of the titanium tube will make the roll wear prematurely and the titanium tube produces waste products. The purpose of drying is to drive out hydrogen atoms in the metal lattice in time, so as to avoid the hydrogen embrittlement phenomenon during the rolling of titanium tubes, and improve the lubrication performance
Application Of Titanium Square Tube
The square tube is used in construction, machinery manufacturing, steel construction, and other projects, shipbuilding, solar power generation bracket, steel structure engineering, electric power engineering, power plant, agriculture and chemical machinery, glass curtain wall, automobile chassis, airport, boiler construction, highway handrail, residential construction, pressure vessels, oil tanks, Bridges, power station equipment, crane transportation machinery and other high-load welding components and so on.
