Sealing (Air Tightness)is a very important point for vaccum valves Sealing of vacuum valves is one of important requirements. only when sealing meets the requirements, the product works. As a product used under vacuum conditions, the vacuum valve not only has standard accuracy in the positioning of the basic functions of the cut-off, but also can effectively serve the needs of vacuum environment management while realizing an effective cut-off function guarantee. To ensure the performance of good management functions, the practical application of vacuum valve products has very important professional requirements. More importantly, it is necessary to ensure that there are good functional standards to achieve the purpose of good service practices. Service standards, as a professional tool with strong practicability, vacuum valves need to achieve good advantages in ensuring that they have good valve guarantee characteristics, actual functions and product quality. 2 important points of seal...

    The new year is approaching, what kind of changes will China's stainless steel industry face? After a year of hard work by all mankind, COVID-19 has been well controlled, but the number of cases in some countries and regions has not decreased, which will affect the production and sales of the global stainless steel industry. We still need to pay attention to the development of the real estate industry in 2021. Due to the impact of the epidemic, the real estate industry will receive strong support from fiscal policies such as local bonds in 2020. Although there will be bond issuance in 2021, it will not increase significantly if there are no major incidents. Therefore, in terms of fiscal policy, the overall fiscal policy will remain stable, and there may be an increase in phases. Compared with the whole year, the increase should be relatively limited. In 2021, we also need to focus on changes in the production of iron ore (1066, 22.50, 2.16%) and coking coal (1659, 60.00, 3...

    What is the stainless steel flange classification? Stainless steel flange is common  stainless steel pipe fittings . The main material of stainless steel flange is 304. SS304 is a more versatile stainless steel. It is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability). . 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to my country's 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 contains 19% chromium and 9% nickel. 304 is widely used stainless steel and heat-resistant steel. Used in food production equipment, chemical equipment, nuclear energy, etc. Stainless steel flanges  are the same as flanges of other materials. There are 13 common types stainless steel flange classification as follows: Flat welding flanges, the pipe must be inserted into the flange welded on the inner ring of the flange. Welding neck flang, flange wi...

  Oil pipelines are composed of oil pipes and their accessories (mainly stainless steel pipe and fittings ), and are equipped with corresponding oil pump units according to the needs of the technological process, and are designed and installed into a complete pipeline system. In order to complete the task of oil unloading and transfer. The oil pipeline system, that is, the pipeline system used to transport petroleum and petroleum products, is mainly composed of oil pipelines, oil transmission stations and other auxiliary related equipment. It is one of the main equipment in the petroleum storage and operation industry, and is also the main source of crude oil and petroleum products. Compared with the railway and highway oil transportation which belong to the land transportation equipment, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. The pipes of oil pipelines are generally stainless steel pip...
