In systems that require high-pressure fluid transmission, such as petrochemicals, natural gas transmission, water conservancy projects, etc., flange joints have become the choice for connecting high-pressure rubber hoses with pipelines or equipment due to their high pressure bearing capacity and good sealing performance. These systems often require joints to withstand high pressure for a long time without leakage, and at the same time be able to adapt to complex working environments.
Vibration and shock environment
In mechanical equipment, vibrating screening equipment, ships and other fields, due to the presence of large vibrations and shocks, the requirements for connectors are extremely demanding. The flange joints of high-pressure rubber hoses can effectively absorb and isolate vibrations and shocks through their good elasticity and damping properties, protecting pipelines and equipment from damage. Its structural design can also compensate for the displacement of pipelines caused by temperature changes, foundation settlement and other reasons to a certain extent.
Corrosive medium transmission
For occasions where corrosive media need to be transmitted, such as chemical, electroplating, pharmaceutical and other industries, the flange joints of high-pressure rubber hoses need to have good corrosion resistance. These joints are usually made of corrosion-resistant materials such as stainless steel and alloy steel to ensure stable performance and sealing effects in harsh media environments.
High and low temperature environments
Under bad temperature conditions, such as high temperature furnaces, low temperature freezers, etc., the flange joints of high-pressure rubber hoses need to have good high or low temperature resistance. These joints can maintain stable sealing and pressure bearing capacity under bad temperature conditions by selecting special rubber materials that are resistant to high or low temperatures, and adopting special manufacturing processes and structural designs.
