Pressure Vessel
Flanges are indispensable connecting components in pressure vessels and are widely used in the pressure vessel industry, primarily in the following areas:
Achieve component connection
Used for connecting the cylinder body to the head, cylinder-to-cylinder, or head-to-tube sheet, enabling different pressurized components to be assembled into a complete pressure vessel structure. It is also commonly employed in the connections of pipelines, valves, pumps, and vessels, facilitating equipment assembly and the construction of integrated systems.
Easy to install and maintain
Flange connections use easy-to-operate fasteners like bolts or nuts, making it simple to disassemble, clean, inspect, and replace components. This significantly reduces downtime during maintenance tasks and lowers overall repair costs. For instance, in equipment such as reactors and heat exchangers that require regular cleaning, flange connections facilitate convenient disassembly and maintenance.
Ensure sealing performance
The flange end face is equipped with a sealing groove, creating a multi-layered sealing structure when paired with a gasket. This design effectively prevents the leakage of toxic, flammable, or corrosive media, ensuring the safe operation of the equipment. The flange, gasket, and bolts are tightly integrated to form a detachable yet secure sealing assembly. By tightening the bolts, the gasket deforms slightly, perfectly filling in any irregularities on the flange’s sealing surface—thus achieving an excellent sealing performance.
Distribute stress
Some types of flanges, such as weld-neck flanges, feature a neck design that effectively distributes stress, making them ideal for high-pressure and high-temperature applications. They can withstand significant pressure and temperature fluctuations, ensuring the structural integrity of pressure vessels even under harsh operating conditions.
Adapting to different operating conditions
Flange materials come in a variety of options, including carbon steel, stainless steel, and alloy steel. The appropriate material can be selected based on the properties of the medium and the operating conditions, ensuring that the flanges meet specific requirements such as corrosion resistance and high-temperature performance for different environments. Additionally, various flange types—such as flat-welded flanges, threaded connection flanges, and socket-weld flanges—are designed to suit different pressure levels, ranging from low to medium pressure applications.
Application
Our product lineup includes options such as butt welds, loose-type flanges, slip-on flanges, flange covers, gear rings, and wind power flanges, among others.
