    titanium tube weld crack problem

    Titanium tube supplier tells us that when titanium welding, titanium tube supplier thermal cracking of welded joints possibility is very small, it is because few impurities in titanium and titanium alloys S, P, C, etc., low melting point from S, P to form a eutectic rarely generated at the grain boundaries, coupled with effective crystallizati Titanium tube supplier tells us that when titanium welding, titanium tube supplier thermal cracking of welded joints possibility is very small, it is because few impurities in titanium and titanium alloys S, P, C, etc., low melting point from S, P to form a eutectic rarely generated at the grain boundaries, coupled with effective crystallization temperature range narrow,<a href="http://www.xinnuotitanium.com/aerospace-titanium-bar-rod/">titanium bar stock</a>  titanium and titanium alloy solidification when a small amount of shrinkage, weld metal does not produce heat cracks.titanium tube supplier and titanium alloy welded seam when oxygenated, higher nitrogen, weld or heat affected zone properties brittle, in the larger weld stress, titanium supplier there will be cold cracking. Characterized by cracks in the weld called a few hours or even longer delay cracks. The study showed that the hydrogen diffusion welding process is the main cause of such cracks. Hydrogen welding process to lower temperature heat affected zone of high temperature diffusion by a deep pond, so that the area to improve the hydrogen content increases TiH2 precipitation amount, increasing the heat-affected zone of brittle, the other due to the volume expansion of the hydride precipitates stress caused by larger organizations , coupled with the hydrogen atom diffusion and aggregation to the high stress areas of the area, resulting in the formation of cracks. This delay prevents cracks approach is to reduce the welded joint main source of hydrogen.

    The rapid development of titanium industry

    Titanium because of its excellent corrosion resistance and high strength and good workability has been processed into a variety of forms and forms of products used in almost all areas.titanium tube supplier  Titanium tube is one of a large class of applications is very broad and is an integral part of the titanium family is a very important sp Titanium because of its excellent corrosion resistance and high strength and good workability has been processed into a variety of forms and forms of products used in almost all areas.titanium tube supplier  Titanium tube is one of a large class of applications is very broad and is an integral part of the titanium family is a very important species. The titanium pipe as a relatively unique form of titanium tube products, is to be rolled into a cold-rolled titanium coil tube after using tungsten inert gas welding the cracks welded together. Because of its excellent resistance to seawater corrosion resistance, self-developed after becoming a variety of condensers and heat exchangers replace stainless steel and brass as the material of choice for heat exchange, and thus is widely used in manufacturing the coastal power plants, nuclear power plants, desalination, petrochemicals and other required seawater as a cooling medium, condensers and heat exchangers.Due to the many constraints of raw materials and processing technology, manufacturing titanium welded over the years it has been controlled by a handful of Japan, the United States, France, Russia and other countries of the professional manufacturer of hands. In China, titanium welded titanium mill product family considered a late start, pre-development of a breed more slowly. Baoji Nonferrous Metals Processing Factory introduction of China's first full titanium pipe automatic production line from the United States, but because the country is not titanium supplier able to produce raw material for titanium welded products - titanium coil, due to the introduction of technology and raw materials procurement difficulties multiple effects, until the late 1990s, the production line really have the production capacity, annual production capacity of only about 200 tons. Until 2005, provided by the French technical support, built two international advanced level, with an annual capacity of 600 tons of preliminary design of automatic titanium pipe production line, the United States provided by raw material supply. Put into operation since 2007, as China was the only professional manufacturer of titanium pipe, with the resources and technical support of shareholders, the company was growing rapidly, the existing titanium pipe production capacity has more than 800 tons, product specifications: diameter 10-40mm wall thickness 0.4-2.1mm, length up to 20m. With the international quality standard of products and services quickly conquered major domestic turbine users, it has become the East steam, Harbin Turbine, Shanghai Electric, Hangzhou Steam, the North heavy, heavy drums and other major equipment manufacturers of qualified suppliers, products widely used in various fields coastal power plants, nuclear power plants, desalination and chemical, of which more than 50% of the products have been used overseas power plant projects. By the end of 2011, total production and marketing of titanium pipe 1,500 tons, the ship became the flagship of the domestic titanium pipe industry, leading the advancement and development of the Chinese titanium pipe industry.

    Titanium tube stock power applications

    Application of Power Industry in titanium tube  Titanium application in electric power industry is very extensive, especially in the nuclear power plant . Nuclear power plant is a new energy facilities , in order to improve the operation and safety of the power plant 's rate is now studying titanium tube stock the use of titanium Application of Power Industry in titanium tube  Titanium application in electric power industry is very extensive, especially in the nuclear power plant . Nuclear power plant is a new energy facilities , in order to improve the operation and safety of the power plant 's rate is now studying titanium tube stock the use of titanium condenser. Of a 1100MW nuclear power plant with a titanium is about 150t, a nuclear power plant of 1100MW of titanium is about 150t, a 600 MW thermal power station with a titanium tube supplier is approximately 60t.    Firepower and nuclear power plant condensers used in the past, use of copper alloy tube. When it was discovered that the corrosion resistance of titanium tubes can greatly superior to copper alloys , began in cooling ( including tube plate ) using a titanium and titanium alloys , and the emergence of a full titanium condenser . Extensive use of titanium and nuclear power plant condensers , turbine blades, pipes, etc. , he accounted for more than 20% of the amount of machining titanium factory .    Another important application of titanium in the power industry is the heat exchanger ocean thermal energy conversion plants , which is the highest utilization rate of metal equipment . Due to the low overall cycle efficiency , heat exchangers are often made very large, multi- metal consumption , investment, and therefore often used titanium . Such a heat exchanger corrosion resistance , long life , low maintenance.    Since the corrosion resistance of titanium and low density , making the production of high-quality material of the steam turbine blade . Titanium blade can be increased without increasing the length of the blade rotor stress , raising the efficiency of the turbine.
