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. The reason is that, on the one hand, the process package of PTA plant in China mainly adopts foreign technologies such as Invista technology and BP technology, so the titanium alloy seamless pipe used in the plant is logically matched with foreign materials. On the other hand, domestic PTA enterprises could not buy domestic titanium welded pipes before, because there was a lack of good titanium strips in China, and high-quality titanium welded pipes were welded with good titanium strips. Finally, a reality is formed that seamless titanium tubes are mostly used in domestic PTA plants. It is imperative to conquer the domestic innovative technology of titanium materials, and Hunan Investment Jintian has made a breakthrough in this field and become a rising star of foreign technology. 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 plate gr7, 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 On this basis, enterprises may also need to use another way of thinking to consider the investment output ratio. Zhou Hui explained:  According to reports, 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,nickel titanium wire, 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
