Pressure Vessel Flange

Pressure vessel flange I. product introduction Pressure vessel is the most widely used equipment and one of the main production tools in petrochemical industry. Due to the process requirements and the installation and maintenance of equipment inner parts, pressure vessels often need to set up the container flange (such as the common shell heat exchanger, reactor, tower, filter, etc.). Pressure vessel flanges are divided into integral flanges, looped flanges and optional flanges according to the connection of flange rings. China's most commonly used JB/T4701 -- 4703 standard pressure vessel flanges have three types: a flat welding flanges, b flat welding flanges and long neck butt welding flanges, of which a, b flat welding flanges are arbitrary type flanges. Ii. Product parameters Specification: 12-3000 Application industry: hvac power buildings water supply pressure vessel accessories, pressure pipe accessories. Product category: flange series Application industry: hvac power building water supply pressure vessel accessories, pressure pipe accessories. Iii. Product advantages High temperature resistance, corrosion resistance, leakage prevention, easy to repair, with good comprehensive performance. Flanges and their gaskets and fasteners are collectively referred to as flange joints. Flange joints are widely used and widely involved parts in engineering design, and they are also the key parts prone to problems in engineering design and use. Flange joint design is one of the important contents of pressure vessel design. In the selection of standard a flange and calculation of non-standard a flange, designers choose the material unreasonable phenomenon is more serious, the use of b flat welding flange or even long neck butt welding flange instead of a flat welding flange situation is more, causing unnecessary waste. Therefore, it is necessary to discuss the selection and calculation of common type a flat welding flange. Application industry: hvac power building water supply pressure vessel accessories,
