Lens pad

2024-06-12View Original

Thread Content

Regarding the specifications for the lens pad: the customer provided information stating a weight of 1500 lb, a size of 4 inches, and a material of 724L. What are the processing standards for this? What requirements should be followed for its production? The carbon dioxide stripping method is used at 1830 degrees; it’s related to urea production processes. I’m seeking guidance from experts

At present, the main domestic technical standards in this field are H1–31–67 \"General Design for High-Pressure Pipes, Fittings, and Fasteners\", JB/T2776–2010 \"High-Pressure Gasketing for Valve Components\", and HG20582–2011 \"Rules for Calculating the Strength of Steel Chemical Vessels\"; Abroad, the main standards include Germany’s DIN 2696-1972 \"Flanges with lens-shaped gaskets\", and the United States’ MSS SP-65-1994 \"High-pressure flanges and threaded stubs using lens gaskets\". In addition, there are also enterprise standards such as Wuhuan Engineering Co., Ltd.’s M20-A81S-95 \"Insulated Flange for Urea Equipment\", Hualu Engineering Co., Ltd.’s TB5002-1999 \"Standards for High-Pressure Urea Fittings\", Zhejiang University of Technology’s ZH300-2009 \"High-Pressure Pipes, Fittings, and Fasteners\", and Sihua Jian’s GH-2007 \"High-Pressure Pipes, Fittings, and Fasteners“. These are the standards that may be applicable in China, so the customer must provide the standard numbers.

The processing standards for the lens pad are primarily based on the information provided by the customer, such as the pressure level (1500 lb), dimensions (4 inches), and material (724L). It needs to be processed in accordance with the relevant standards issued by ASME (American Society of Mechanical Engineers) or similar organizations. For example, reference can be made to the ASME B16.20 standard, which covers the design, material, and dimensional requirements for metal gaskets used in flange connections. For specific applications, such as carbon dioxide stripping and urea plants, chemical stability and corrosion resistance under these particular conditions also need to be considered. It is recommended to consult experts with the appropriate qualifications for detailed guidance. .
