Pipe Couplings – HS-Umformtechnik

At SUTEIN, together with HS Umformtechnik, we offer a complete range of pipe couplings designed for pneumatic conveying systems for bulk solids.

In these installations, the connection between pipe sections is a critical point: it directly affects sealing, efficiency and process continuity.

Our pipe couplings are designed to ensure safe, leak-tight and easy-to-maintain installations, both in pressure and vacuum conveying systems.

Manufactured with high-quality materials and designed for demanding environments, they allow welding-free installation, reducing assembly time and facilitating maintenance and component reuse.
