Zirconium pump valve successfully developed to fill the gap

Acetic acid is an extremely important chemical product. Acetic acid and the catalysts it uses are highly corrosive, and iodide ion is also extremely corrosive, and it is a common condition in high temperature conditions. Therefore, it is above 120°C. In the high temperature environment, the selection of acetic acid devices is critical. A large number of important static equipment, valves, and fittings have been selected for their highly corrosion-resistant zirconium and zirconium alloys. Zirconium is an active metal and has a strong suction capability at high temperatures. Therefore, the smelting and casting and heat treatment of zirconium must be carried out under vacuum or inert gas protection. China's zirconium pump valves have been dependent on imports in the past.

Xi'an Pump & Valve General Factory Co., Ltd. has the only complete vacuum smelting and casting production line in the pump valve industry, and has more than 20 years of experience in R&D and manufacturing of titanium valve valves. In 2006, it began to take active actions to actively overcome difficulties and consciously provoked the burden of developing and manufacturing zirconium pump valves. After years of exploration and research, especially the joint efforts of scientific research, design, manufacture and users in the past two years, independent innovation, joint research, developed a unique smelting casting process for zirconium products, localization of zirconium pump valves. Work has been very effective, can produce a variety of grades in accordance with the United States ASTM standards and national standards of chemical composition requirements and mechanical properties of zirconium castings. Successfully developed a series of zirconium valve products for use in the acetic acid industry, ending the history that this kind of product only relied on imports to fill the gap in the domestic zirconium valve production.
