Absperrkoerpers

Absperrkoerpers, often translated as "barrier bodies" or "shut-off bodies," are devices used in various industrial and technical applications to temporarily or permanently block the passage of fluids or gases. Their primary function is to isolate a section of a pipeline, vessel, or system for maintenance, repair, or operational control.

These devices come in a wide range of designs and materials, tailored to specific applications. Common types include simple plugs, inflatable bladders, and more complex mechanical valves. The choice of absperrkoerper depends on factors such as the operating pressure and temperature of the system, the type of medium being handled (e.g., water, gas, chemicals), the required sealing performance, and the duration of the blockage.

In pipeline applications, absperrkoerpers are frequently used during hydrostatic testing to divide sections of newly laid pipes. They are also employed to isolate damaged sections for repair without draining the entire system. In manufacturing processes, they can serve as temporary stoppers to control flow during different stages of production. Furthermore, certain types of absperrkoerpers are designed for emergency shutdown procedures, rapidly sealing off a system to prevent hazardous releases. The materials used can range from rubber and plastics for lower-pressure applications to robust metals like steel and alloys for high-pressure and corrosive environments. Their reliable operation is critical for safety and efficiency in many industrial settings.
