The production process of titanium seamless pipes is complicated. Conventional three-roller or multi-roll mills and drawing machines are used to roll or draw a certain size of billet through multiple passes, and finally produce seamless pipes after diameter reduction and wall reduction. The production efficiency and yield rate of this process are low. Titanium seamless pipes from sponge titanium to pipes, through rolling or drawing, the material waste is large, the production rate is only about 50%, and mass production cannot be achieved, and the production cycle is relatively long. The titanium welded pipe is produced through an automated continuous production line, using a titanium strip coil with uniform wall thickness through cold bending forming, welding, online heat treatment, sizing and straightening, non-destructive testing and air tightness testing.
From sponge titanium to welded pipe, the material utilization rate is usually about 80%. If the titanium tape is used as the raw material, the material utilization rate is more than 95%. With the rapid development of the domestic titanium industry and the increasingly mature welding technology, the production efficiency of titanium welded pipes will also be greatly improved, the quality stability, consistency and production efficiency will be higher, and can be cut to the required length according to customer requirements , Short delivery time, high material utilization rate, unit cost will be lower than seamless tube.
