Can SOSHH® flexible sleeves withstand negative pressure (vacuum) in pneumatic conveying systems?
Yes. While standard flexible sleeves may collapse under heavy vacuum, causing powder blockage, SOSHH® offers reinforced solutions. For high-vacuum pneumatic conveying lines, we utilize our PURF (Fiber Reinforced Polyurethane) grade or incorporate internal stainless steel support rings (anti-collapse rings) to maintain the sleeve's structural integrity even under heavy negative pressure.
