Tube made of titanium alloy plate is also called titanium tube, which is a titanium tube made of titanium plate or titanium band after crimping and welding. Titanium alloy plate production process is simple, high production efficiency, many varieties and specifications, less equipment investment, but the general strength is lower than seamless titanium tube. Since the 1930s, with the rapid development of high-quality titanium continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, the variety and specifications of titanium alloy plates are increasing, and they have replaced in more and more fields Seamless titanium tube. Titanium alloy plate is divided into straight seam titanium tube and spiral titanium tube according to the form of welding seam. The production process of the straight seam titanium tube is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of spiral titanium tubes is generally higher than that of straight slit titanium tubes. It is possible to produce titanium tubes with larger diameters from narrow blanks, and to produce titanium tubes with different diameters from blanks of the same width. But compared with the straight pipe of the same length, the length of the weld is increased by 30-100%, and the production speed is lower. Therefore, most of the smaller diameter titanium tubes use straight seam welding, and the larger diameter titanium tubes mostly use spiral welding.
1. Titanium alloy plate for low-pressure fluid transportation (gb/t3092-1993) is also called general titanium tube, commonly known as black tube. It is a titanium alloy plate used for conveying water, gas, air, oil, heating steam and other generally lower pressure fluids and other uses. The wall thickness of titanium tube is divided into ordinary titanium tube and thickened titanium tube; the form of the tube end is divided into non-threaded titanium tube (light tube) and threaded titanium tube. The specification of the titanium tube is expressed by the nominal diameter (mm), which is an approximate value of the inner diameter. It is customary to use inches, such as 11/2. In addition to being directly used to transport fluids, titanium alloy plates for low-pressure fluid transportation are also used as raw pipes for galvanized titanium alloy plates for low-pressure fluid transportation.
2. Low-pressure fluid transportation galvanized titanium alloy plate (gb/t3091-1993) is also called galvanized welding titanium tube, commonly known as white tube. It is a hot-dip galvanized welding (furnace welding or electric welding) titanium tube used to transport water, gas, air, oil, heating steam, warm water and other generally low-pressure fluids or other purposes. The wall thickness of the titanium pipe is divided into ordinary galvanized titanium pipe and thickened galvanized titanium pipe; the form of the pipe end is divided into non-threaded galvanized titanium pipe and threaded galvanized titanium pipe. The specification of the titanium tube is expressed by the nominal diameter (mm), which is an approximate value of the inner diameter.
