Titanium valve applications
1, aerospace engineering
Titanium and titanium alloy high strength, low density and other properties make it commonly used in aerospace engineering. Such as a large number of aircraft on the pipeline a large number of titanium alloy valves, valve types involving regulating valve, globe valve, check valve, needle valves, plug valves, ball valves and butterfly valves. Titanium for the valve are pure titanium (ASTMB367C2) and titanium alloy (Ti-6Al-4V (ASTMB381F5), Ti-6Al-6V-2Sn, Ti-6Al-2Sn- 4Zr-2Mo, Ti-6Al-2Sn- 4Zr -6Mo Ti-10V-2Fe-3Al Ti-5Al-2.5Sn Ti-8Al-1Mo-1V Ti-13V-11Cr- 3Al and Ti-8Mo-8V-2Fe- 3Al and Ti-11.5Mo-8V -6Al-4.5Sn, etc.), but the use of pure titanium and titanium alloy Ti-6Al-4V is more common. Tianyuan used in aviation engineering fasteners timber selection Ti-6Al-4V. Russia uses BT16.
2, chemical engineering
Titanium valve as a titanium alloy tube fluid delivery control of key system components in chemical engineering has a very wide range of uses. Projects such as chlor-alkali project, salt industry, ammonia project, ethylene project, nitric acid project and acetic acid project involving strong corrosive medium and environment must use titanium alloy with excellent corrosion resistance and control and regulation in medium conveying pipeline Parts must be extensive use of titanium valve. Large-scale fine triumphalism acid project can be used as a typical titanium valve, because of its media mainly involves certain impurities high temperature and high concentrations of acetic acid, harsh environment, special medium, the use of highly corrosion-resistant materials. Therefore, a large number of applications of different types and sizes of titanium valves, valve types involved gate valve, globe valve, check valve, safety valve, ball valve and butterfly valve. Large-scale domestic use of fine triumphalism acid project titanium valve body used ASTMB367C2 (castings) or ASTMB381F2 (forgings), valve parts and more use of ASTMB381F5.
Valves with fasteners as an important valve parts, valve design, manufacturing is also essential. Foreign generally divided into two types, for contact with the media use ASTMB381F5, and for the valve outside the media do not come into direct contact with the fastener, often choose to use a certain surface treatment of alternative materials, such as stainless steel ASTMA194-8M, etc., can reduce Cost, procurement is relatively easy.
China has designed and manufactured a large size (DN500) titanium valves, such as forged ball valves, butterfly valves and check valves, achieved in a large volume of refined triumphalism acid project supply and successful application. Titanium valve widely used in the chemical industry, but we must point out that it is not suitable for any chemical medium. Among them, hydrochloric acid, hydrochloric acid, sulfuric acid, orthophosphate acid and concentrated oxalic acid, formic acid, trichloroacetic acid, trifluoroacetic acid and extremely corrosive aluminum chloride all have serious corrosion effects on titanium and titanium alloy. Titanium valve not suitable for such chemical medium, should pay attention to in use.
3, nuclear power project
Since all nuclear power plants are built along the coast, many facilities in nuclear power plants are involved in the unusual medium of seawater. Titanium and titanium alloy valves have excellent seawater corrosion resistance, making them a huge amount of use in atomic power projects. Nuclear power valves in the nuclear power plant are the use of a large number of medium conveying control equipment. Nuclear power plant is an essential part of the safe operation. Valve configuration to see the situation, the valve accounted for 33.6%, diaphragm valve accounted for 26.2%, valve accounted for 12.8%. In the colossal amount of valves, titanium valves occupy a considerable proportion of the main titanium material used to be proof-tested titanium-based.
4, other projects
Titanium and titanium valves in the offshore platform, paper, food, medicine and other projects are very common. In recent years, the exploitation of offshore oilfields has entered a period of rapid development. Demand for titanium alloy valves for offshore platforms has been increasing year by year. The principal concerns are broken ball valves, check valves and multi-way valves. Paper engineering involves strong alkali medium. Medium corrosion performance is extremely strong. Paper industry pipes, pumps, valves, fans and mixers are often made of titanium alloys, including pure titanium ball valve and globe valve applications such as larger. Because titanium and titanium alloys are bio-inert, that wishes to say, they do not cause any toxic effects on the human body or other organisms. Therefore, titanium and titanium alloy devices are commonly used in food processing and pharmaceutical engineering. High-end food processing enterprises and pharmaceutical plants are applied to titanium equipment, pipelines and valves, titanium valves are mainly made of titanium ball valves and butterfly valves.
