Cleaner production is an important indicator of the degree of civilization of a company. In recent years, Wuhua Petrochemical has always forgotten the responsibility and mission of environmental protection while accelerating the pace of enterprise development and increasing production capacity. In order to maximize the control of industrial waste gas, waste water, and waste slag discharge, the company has further increased its control over the source of environmental pollution since 2007. It has completed a series of advanced wastewater treatment systems and flue gas desulphurization devices for coal-fired boilers of chemical fertilizers. Technical research and transformation. After the modified equipment was put into operation, the expected ideal results were achieved. Not only the industrial wastewater and exhaust emission control levels have been greatly improved, but also it has played an exemplary role in improving the atmospheric environmental quality of Urumqi and realizing the total amount of major pollutants. .
This year, the company has arranged for the construction and continued construction of 11 energy-saving emission reduction projects. Among them, the sulfur recovery unit is a key project for commissioning. After the unit is put into operation, it not only solves the problem of environmental pollution caused by the discharge of acid gas from refining, but 99.9% of sulfides can be converted into sulfur products.
Across the pond, you will find the Deutsches Institute fur Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a DIN Flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME steel flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.
The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck, flanges, and blind flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.
The most common metric type flanges fall under the following categories:
DIN 2501 through 2503 for flat ring flanges
DIN 2512 through 2519 for alternate face flanges
DIN 2627 through 2633 for weld neck flanges
DIN 2641 through 2642 for lap joint flanges
DIN 2565 through 2569 for threaded/companion flanges
DIN 2527 for blind flanges
