Titanium tubes are light in weight, high in strength, and superior in mechanical properties. They are widely used in heat exchange equipment, such as tubular heat exchangers, serpentine tube heat exchangers, condensers, evaporators and transportation pipelines. At present, many nuclear power industries use titanium tubes as standard tubes for their units. The titanium tube is made by an extrusion process, and the welded titanium tube is made by crimping and welding the plate. Generally, seamless titanium pipe has a relatively small wall thickness and a relatively small diameter.
Technical requirements for titanium tube:
1. The allowable deviation of the outer diameter of the pipe meets the requirements of Table 1.
2. The length of the pipe should meet the requirements of Table 2.
3. The allowable deviation of pipe wall thickness should not exceed ±12.5% of its nominal wall thickness. The allowable deviation of pipe wall thickness is not suitable for the weld of titanium welded pipe.
4. The chemical composition of titanium and titanium alloy tubes meets the requirements of GB/T3620.1, and the allowable deviation of the chemical composition meets the requirements of GB/t3620.2 when the buyer re-inspects.
5. Within the range of fixed length or multiple lengths of the pipe, the allowable deviation of the fixed-length is ±10mm, and the multiple lengths should also be included in the cut amount when the pipe is cut. Each cut should be 5mm.
Titanium alloy has high strength, low density, good mechanical properties, toughness and corrosion resistance. In addition, titanium alloys have poor process performance and difficult cutting processing. In hot processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen, and carbon. It also has poor abrasion resistance and complex production processes.
