【Major Industrial Equipment in the Chemical Industry】058-60 inch Class300 Large-Diameter Fixed Ball Valve
Thread Content
The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, 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 such equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! *********************************** This \"giant\" ball valve, which is 3.5 meters tall and weighs over 40 tons, is the first prototype of a 60-inch Class300 large-diameter fixed ball valve in China. Its creation marks a new milestone for Jiangsu Province’s valve industry, as well as for China’s equipment manufacturing sector, in the field of valves. With the increase in large-scale domestic and international projects in the fields of hydropower, oil and gas, there is a growing demand for high-medium pressure, large-diameter pipeline ball valves; however, the market share for these products is largely held by foreign leading valve manufacturers. The production of 60-inch Class300 large-diameter fixed ball valves will completely break the foreign monopoly on such products, providing a solid foundation for the development of major projects in our country. At the recommendation of the Yancheng Petroleum Machinery Industry Association, the China General Machinery Industry Association held an appraisal meeting for this product in Yancheng. The expert committee at the meeting stated that the prototype of this product passed the appraisal, and noted that Jiangsu Mingtongfulu Fluid Control Equipment Co., Ltd. has implemented the policy of local production of key equipment through its own innovative efforts, thereby demonstrating the company’s sense of responsibility and commitment.
Cheer for Made in China, give support to chemical equipment!
One day, we will make everyone in the world** look up to us

There is a shared expectation; in fact, many Chinese chemical processing equipment have already been exported overseas, especially container-type equipment

Long-distance pipelines are global in nature; they are energy supply lines that extend from the Arctic Circle to the equator, from mountains to the seabed, and from plateaus to deserts, passing through earthquake zones, swamps, permafrost, rivers, lakes, and slopes along the way. Some are installed, while others are buried directly underground; they are operated in the field, making maintenance difficult, and are required to have a service life of 30 years. Generally used for transporting crude oil and natural gas, these fluids are sulfur-containing, contain rust and metal particles despite being processed, and require zero-leakage sealing. The harsh operating conditions as well as the importance of energy supply lines impose strict technical requirements on pipeline ball valves. 1. Strength and toughness: In addition to withstanding the pressure of the internal fluid, the valves must also withstand the load exerted by the foundation. Axial tensile and compressive forces resulting from changes in ambient temperature must be taken into account, along with external loads caused by landslides, ground subsidence, and floods. In cold and frozen regions, the low-temperature impact toughness of the materials is also important to prevent brittle fracture at low temperatures. For fully welded ball valves, the welds and heat-affected zones require that their fracture toughness (CTOD) be considered in accordance with fracture mechanics theory. 2. Sealing requirements at level zero: The valve is required to provide a seal at level zero in order to ensure effective isolation of the pipeline at the downstream end. The impact of metal particles present in the medium on this level-zero seal must also be taken into account; a metal-to-metal seal serves as the primary seal, while PTFE/rubber in contact with metal functions as the secondary seal. Emergency sealing measures must be in place in case the seal fails. 3. Equipped with fire safety and anti-static functions ； The design of pipeline ball valves must take fire safety into account; in the event of a fire, the external and internal leaks from the valve must not exceed the leakage standards specified in API607 ； When the sphere is held by non-metallic materials, static electricity may be generated; it must be in electrical contact with the valve body. At 24VDC, the resistance value is
