The Ministry of Science and Technology recently launched several state-level science and technology projects in 2007. Among the participating companies, Changzhou Niutang Chemical Factory Co., Ltd. was selected to undertake two key initiatives: the integration and innovation of sucralose technology along with its industrialization, and the development of a p-hydroxyphenethyl alcohol project. Both projects were recognized at the national level—sucralose was included in the National Torch Plan, while p-hydroxyphenethyl alcohol was listed under the National Key New Product Program. The company received a central government research and development grant of 300,000 yuan for these efforts. Sucralose is a unique sugar substitute that closely resembles sucrose in taste and is suitable for most consumers. It is 650 times sweeter than regular sugar, contains zero calories, and does not participate in human metabolism. Additionally, it remains stable at high temperatures, making it ideal for a wide range of food and beverage applications. The project aims to establish a production capacity of 600 tons per year by 2010, with projected sales revenue reaching 900 million yuan. p-Hydroxyphenethyl alcohol serves as a critical intermediate in the synthesis of a new generation of drugs, such as metoprolol and betaxolol, which are widely used in the treatment of hypertension. These medications are considered first-line therapies due to their effectiveness and safety profile. The project focuses on integrating and innovating key technologies in the synthesis of p-hydroxyphenethyl alcohol, with an expected annual production capacity of 300 tons. Both projects are backed by strong intellectual property rights. The sucralose initiative has filed seven invention patents, including one U.S. patent and two granted patents. Meanwhile, the p-hydroxyphenethyl alcohol project has already secured one authorized invention patent. These achievements highlight the company’s commitment to technological advancement and innovation in the chemical industry.

Flat Face Flange

Marine flanges are flanges used on ships, and flanges are parts that connect pipes to pipes. connected to the pipe end. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected. The flanges are sealed with gaskets.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections.
