 leading technology, efficient operation and low energy consumption have also become the distinct characteristics of the current operation of the industry. Expand the full text The production process of PTA includes complex chemical processes such as mixing, hydrogen production, reaction, evaporation, condensation, extraction, separation and drying, as well as processes such as liquid phase conveying, gas phase conveying, gas-liquid mixed phase conveying,titanium sheet grade 5, solid-liquid slurry conveying and solid powder conveying. Its production process is also accompanied by high temperature, high pressure, strong corrosion of process media and other prominent characteristics. Influenced by the process and production characteristics, titanium plates and tubes with high performance and corrosion resistance have been widely used in PTA plants in the international market in recent years. Because the titanium alloy has strong corrosion resistance, the corrosion resistance is far superior to that of stainless steel, the resistance to pitting corrosion, acid corrosion and stress corrosion is particularly strong, and the titanium alloy also has excellent corrosion resistance to alkali, chloride, nitric acid, sulfuric acid and the like. At the same time, it has high strength, tensile strength of 686 MPa to 1176 MPa, and density of 4.5 G/cm3, which is only about 60% of steel. Titanium tubes are mainly used for heat exchange tubes of condensers and heat exchangers in PTA plants,nickel titanium wire, with high reliability and long service life. In Norway, Japan and other countries, titanium alloy materials are widely used in related devices in the petroleum field. Titanium alloy materials are used in domestic PTA plants in recent years, but titanium alloy materials are mainly imported.  Compared with some titanium material enterprises that have been established for decades, Hunan Investment Jintian, which has only 10 years of history, titanium tubing price ,titanium seamless tube, is a "recruit" in the domestic titanium industry. However, with a series of innovative technologies, this "recruit" has grown rapidly into one of the "top three" titanium enterprises in China, forming an international advanced and domestic first-class titanium industry platform. Its R & D and production of large coil weight wide titanium strip, high performance titanium welded pipe, high performance titanium alloy bar and other core technology products fill the domestic gap and break the foreign monopoly. At present, the annual production capacity of Xiangtou Jintian Titanium Belt is 10000 tons, and the annual production capacity of titanium pipe is 5000 tons, which is the first in Asia and the second in the world. Behind the glory, there is often an unknown story of hardship. At first, we knew titanium processing was difficult, but after 10 years, we didn't expect it to be so difficult. At that time, there was a lack of technology, talent and resources, and we were "recruits", so what should we do? Innovation must be accelerated. At that time, we were full of ambition and set a goal for ourselves-to fill the gap in the domestic market, the titanium steel joint model we created was an innovative move. However, in the process of creation, we have no experience to draw lessons from, so we can only work,  the wall thickness of the seamed titanium pipe produced by Xiangtou Jintian is getting thinner and thinner, which is only 0.2 mm at present. PTA is one of the important application markets of titanium tube in civil field. With the continuous upgrading of materials,titanium tubing price, there is still much to be done in the refinement of PTA plants in China. We hope to expand the use of titanium tubes in PTA plants, but also to improve the profit margin of PTA enterprises. We are confident that together with PTA enterprises and related equipment enterprises, we will do a better job in the refinement of PTA plants and production in China and further promote the high-quality development of PTA industry. Zhou Hui is confident about the application and expansion of seamed titanium tubes in PTA plants. Return to Sohu to see more Responsible Editor:. yunchtitanium.com
