Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4 have high strength, good plastic toughness and corrosion resistance, and are more and more widely used in aerospace, shipbuilding and chemical industry. Titanium welded pipe is made of cold-rolled sheet coils, namely titanium coils. The circumference of the outer diameter of the finished pipe is subtracted from the required width of the weld as the width of the strip. After such strips are continuously rolled and formed, they are welded by TIG. is the finished product. The outer diameter of the production pipe diameter is 10~50mm, and the wall thickness is 0.3~2mm. After welding, there is no need to hammer welding slag and grinding, the surface is very smooth, and secondary processing such as pipe expansion and pipe bending can also be performed, which is almost no different from seamless pipes.

Henan Chalco has a fully automatic Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4 production line using the French non-melting electrode argon arc welded pipe technology, and the welding speed of a single gun can reach 8m/min. The outer diameter of the welded pipe is 10-40mm, and the wall thickness is 0.3-2.1mm.

Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4 development and application of:

In China, the production technology of low-strength, low-alloyed titanium seamless pipes is relatively mature. In some pipes that need to withstand high pressure and structural stress, thick-walled titanium seamless pipes are generally used. However, due to the influence of factors such as low yield of titanium seamless pipes and long delivery cycle, vigorously developing titanium welded pipes has become a trend in the titanium pipe industry. Compared with titanium seamless pipes, the comprehensive advantages of titanium welded pipes are becoming more and more obvious. In Japan, the United States, Europe and other countries and regions, titanium welded pipes are gradually replacing titanium rolled pipes.

2.1 The mechanical properties of titanium welded pipe and titanium seamless pipe are basically the same

Taking titanium and titanium alloy tubes for heat exchangers and condensers as an example, the national standard is GB/T 3625-2007, and the American standard is ASTMB338. Titanium welded tubes and titanium seamless tubes are different in terms of chemical composition, mechanical properties and process properties. Not much, even the same. With the progress of welding and heat treatment technology of titanium welded pipes, domestic thin-walled titanium welded pipes generally adopt single-gun or multi-gun TIG/PAW self-fusion welding, and after welding, an online heat treatment process is adopted. , The microstructure of the heat-affected zone is basically close, and the welding stress is eliminated at the same time, so that the weld structure is uniform. By comparison, it is found that the composition of the weld seam of the titanium welded pipe is basically the same as that of the base metal, and the mechanical properties and corrosion resistance of the weld seam are the same as those of the base metal.

2.2 The appearance and quality of Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4 are better than those of titanium seamless pipes

Titanium welded pipe is welded by cold-rolled coil, with uniform wall thickness, good concentricity, good finish, and it is not easy to scale in the pipe. In particular, thin-walled titanium tubes cannot meet their technical requirements at all by seamless rolling. It is difficult to achieve a wall thickness of less than 1 mm for titanium seamless pipes after rolling or drawing processes; while titanium welded pipes can achieve wall thicknesses of 0.5 mm or less, saving a lot of materials and costs. At the same time, due to the thin wall thickness of the titanium welded pipe, a higher heat transfer coefficient can be obtained and a better heat transfer effect can be achieved.

2.3 The cost and environmental advantages of Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4 are outstanding

The production process of titanium seamless pipes is complicated. Conventionally, three-roll or multi-roll mills and drawing machines are used to roll or draw a certain specification of tube blanks in multiple passes, and finally produce seamless pipes after reducing diameter and wall. The production efficiency and yield of this process are low. Titanium seamless pipe from sponge titanium to pipe, through rolling or drawing, material waste is large, the yield is only about 50%, and large-scale mass production cannot be achieved, and the production cycle is relatively long.

The Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4is produced through an automated continuous production line, using titanium coils with uniform wall thickness through cold bending, welding, online heat treatment, sizing and straightening, non-destructive testing and air tightness testing. From sponge titanium to welded pipes, the material utilization rate is usually about 80%. If the titanium coil is used as the raw material, the material utilization rate is above 95%. With the rapid development of the domestic titanium industry and the maturation of welding technology, the production efficiency of titanium welded pipes will also be greatly improved, and the quality stability, consistency and production efficiency will be higher, and can be cut to the required length according to customer requirements. , The delivery time is short, the material utilization rate is high, and the unit cost will be lower than that of seamless pipes.

Titanium seamless pipes are usually produced by rolling or drawing processes. A large amount of rolling oil, drawing oil, etc. will be used in the production process, and the production site will be seriously polluted. After the titanium tube is rolled and drawn, it is necessary to degrease and pickle the grease and dirt on the inner and outer surfaces of the tube, and the pickling process causes great environmental pollution. In order to ensure the health of operators and protect the environment, it is necessary to increase protective equipment and protective measures, thus increasing capital investment and correspondingly increasing product production costs. Titanium Welding Rolled Pipe TA1 TA2 TA9 TA10 TC4 are continuously produced in large quantities through automated production lines, with stable quality and high production efficiency. Except for a certain amount of energy consumption such as water and electricity, there is almost no pollution to the environment during the production process.

With the deepening of the understanding of titanium welded pipes, the application of titanium welded pipes in the petrochemical industry
