Overview of Development of Titanium and Titanium

Original Title: Overview of Development of Titanium and Titanium Alloy Longitudinal Welded Pipe in China Review on Development of Titanium and Titanium Alloy Longitudinal Welded Pipe in China Abstract: In this paper, the development course, application, production technology and product standard of titanium and titanium alloy longitudinal welded pipe in China are introduced and commented in detail, and the future devst of the titanium weaterials are widely used in chlorine-related media. For example, titanium materials have been widely used in manufacturing equipment, pipelines and pipe fittings in the production of ion-exchange membrane caustic soda. In addition, titanium pipelines are used to transport media in formic acid, acetic acid, propylene oxide and other chemical projects to solve the problem of pipeline corrosion and prolong the service life of pipelines. In the titanium pipe,titanium bar gr5, the chemical composition, mechanical properties and process performance of titanium welded pipe and titanium seamless pipe are basically the same.However, titanium welded pipe has the advantages that titanium seamless pipe does not have in practical application.Titanium welded pipe can achieve big bore and ultra-large h specific strength, it has attracted wide attention and use in the industrial field since its development. At present, small bore titanium welded tubes (nominal size DN100 and below) have been used in various condensers and heat exchangers to gradually replace titanium seamless tubes as the preferred material for heat exchange tubes, while big bore titanium welded tubes (nominal size DN100 and above) are also widely used as industrial pipelines in chemical, petroleum, petrochemical, salt making, pharmaceutical and marine engineering industries.

Development Course of Titanium Welded Pipe in China In the early days of the founding of the People's Republic of China, titanium was only used in the military industry and belonged to the national strategic control materials. It was not until the 1970s that titanium was used in the chemical field of civil industry. So far, it has a history of more than 40 years. As an excellent corrosion-resistant structural material,3d titanium wire, titanium has established its irreplaceable position.  with an annual capacity of only about 200 tons. In the mid-1990s, Changzhou, Titanium welding pipe ,titanium exhaust tubing, China and Valtimet Company of France jointly established Falinuo Great Wall Welded Pipe Co., Ltd. and introduced three small bore welded pipe production lines to produce titanium welded pipes. In order to reduce the cost of titanium pipes,titanium tubing price, some domestic manufacturers have successfully developed titanium/steel composite pipes (base pipe material is steel, lining or inner cladding material is titanium) with reference to SY6623-2005 "Bimetal Composite Pipe". The cost of titanium/steel composite pipe is 30 ~ 50% less than that of titanium pipe, and composite pipe will be the development direction of anti-corrosion pipeline in the future.
