Original title: What are the advantages of using titanium tubes in reverse osmosis automatic ultrapure water equipment? As water pollution is becoming more and more serious, both industrial production and people's drinking water are threatened. Nowadays, with the development of science and technology, the development of reverse osmosis automatic ultrapure water equipment can solve this problem well. The water quality treated by reverse osmosis automatic ultrapure water equipment meets the national industrial and ultrapure water standards, so reverse osmosis automatic ultrapure water equipment is essential for healthy water use. That is,titanium bar gr7, ultrapure water is treated by distillation and reverse osmosis. The titanium tube in the reverse osmosis full-automatic ultrapure water equipment will gradually replace the original copper alloy tube. Compared with the two, the titanium tube has the following advantages: 1. Under the same operating conditions, the wall thickness of titanium pipe is thinner and the amount of pipe used is less. Generally,Titanium 6Al4V wire, the wall thickness of copper alloy pipe is 0. 9mm-1。 2mm; replaced by titanium tube ? Where corrosion is low, the available wall thickness is 0. 5mm thin-walled tube. And 2, the titanium tube has good thermal conductivity. The thermal conductivity of titanium is 17 W/ (m · K), that of aluminum brass is 100 W/ (m · K), titanium tubing price ,ti6al4v eli, and that of 70/30 cupronickel is 29 W/ (m-k). The thermal conductivity of titanium is the lowest. However, the use of thin-walled titanium tubes, although the thermal conductivity is worse than that of aluminum brass, is comparable to that of 90/10 cupronickel and better than that of 70/30 cupronickel. And 3, the cost performance of the titanium tube is higher. The price of titanium tube can be compared with that of copper alloy tube. Because of the low density of titanium, the mass of titanium tube with the same length is only 50% of that of copper alloy tube when the wall thickness of titanium tube is the same. When the wall thickness of titanium pipe is 50% of that of Copper alloy tube, the mass of titanium pipe with the same heat transfer area is only 1/4 of that. It can be seen that titanium tubes are competitive in terms of price. Expand the full text And 4, the service life of the titanium tube is longer. Because the water is often mixed with sediment and marine organisms, they attach to the heat transfer tube and the tube end, which will erode the copper alloy tube, and the copper alloy will also be corroded by Br- in the water. However, in use, the hydrogen introduced from the external environment is called external hydrogen, specifically, active hydrogen atoms are generated on the surface of the metal through the following ways, and then enter the metal: (1) Titanium equipment is placed in a medium containing molecular hydrogen,titanium sheet grade 5, such as a high temperature hydrogen atmosphere. (2) Hydrogen produced by general corrosion or local corrosion of titanium is absorbed by titanium. For example, crevice corrosion is often accompanied by hydrogen absorption. (3) Hydrogen produced when titanium and electronegative metals are subject to galvanic corrosion or cathodic protection. The latter two kinds of hydrogen embrittlement caused by electrochemical corrosion of the cathode are more frequent and can occur without high temperature and high pressure, which should be paid more attention to.
