The results of the 2021 recognition program for the first sets of equipment in Zhejiang Province were announced; the “Ultra-large LNG-powered ship fuel tank pump tower” submitted by Jiaxing Yada Pipeline System Co., Ltd. was recognized as China’s first such set of equipment. It is reported that this represents another significant scientific achievement by the company, following the inclusion of its \"ultra-large dual-fuel powered ship digital vacuum pipeline system\" as one of the first such systems in Zhejiang Province. It also illustrates Xinfeng Town’s efforts to improve its business environment and strengthen its manufacturing capabilities.
The pump tower is suspended upside down inside the fuel film tank; its mast features a truss-type structure supported by triangular cross-section members. Holes are provided in the truss support pipes, which helps to address the problems of sagging, swaying, and impacts that occur during the ship’s navigation； At the same time, a solution involving reserved expansion space is adopted to address the issue of length deformation at temperatures of minus 163 degrees Celsius and plus 40 degrees Celsius.
The entire pump tower is made of low-temperature resistant austenitic stainless steel; however, the significant shrinkage that occurs after welding can lead to deformation, which in turn affects subsequent maintenance tasks. The total length of the pump tower components, from the top platform to the bottom, is 30 meters, and it is possible to maintain a straightness tolerance of ±4 mm. What kind of concept is this? A total length of 30 meters is equivalent to the height of ten floors. The deviation in the straightness of a mast of such length is only 4 millimeters, which is practically negligible. Reaching this level requires precision control of components and techniques to prevent shrinkage deformation during welding, the use of counter-deformation measures during processing and welding, as well as post-weld correction.
It’s tough in the scorching summer heat! Keep up with heat prevention and cooling! Clarify the key tasks! Safety analysis must not be neglected! ----------------------------------------------The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and localization of equipment. We invite everyone to share, discuss, and exchange ideas – let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ 【Major Chemical Equipment in a Major Country】Series Summary Post – Being Updated https://bbs.hcbbs.com/thread-3366481-1-1.html (Source: Huahai Chuanliu – Haichuan Network)
Minus 163 degrees Celsius – that’s way too low
