New HS stainless steel pipe coupling for pneumatic conveying: enhanced sealing and reliability

Nueva Abrazadera acero inoxidable HS

In pneumatic conveying systems for bulk solids, there are components that often go unnoticed… until they fail.

One of them is the connection between pipe sections.

When it is not properly designed, issues arise that directly impact the process:

  • Product leakage or loss of sealing
  • Uncontrolled air ingress
  • Misalignment between pipe sections
  • Vibrations leading to premature wear
  • Downtime for adjustments or maintenance

In short, critical points that affect the efficiency, safety and continuity of the industrial process.

A solution designed to prevent leaks and improve system reliability

At SUTEIN, we are about to incorporate into stock a new HS Umformtechnik stainless steel pipe coupling, specifically designed for demanding pneumatic conveying applications.

A solution engineered to ensure secure, leak-tight and durable pipe connections in industrial installations.

Discover our solutions for pneumatic conveying of solids.

What does this new HS coupling offer?

This new range has been developed with a clear objective:
to ensure perfect pipe connections and minimize operational issues.

Key advantages of these couplings for pneumatic conveying: 

  • High sealing performance
    Prevents product leakage and pressure loss, improving system efficiency.

  • High resistance to abrasion and corrosion
    Manufactured in AISI 304 stainless steel, ideal for demanding environments and abrasive products.

  • Designed for demanding operating conditions
    Withstands up to 6 bar pressure and vacuum conditions up to 0.8 bar (depending on diameter).

  • Certified materials for food and chemical industries
    Gaskets available in NBR, EPDM or silicone, compliant with FDA and EC1935/2004.

  • Fast and secure installation
    Robust fastening system with M12/M16 bolts depending on diameter, optimizing installation and maintenance times.

  • Wide diameter range
    Available from Ø65 mm to Ø219.1 mm, with lengths of 150 and 200 mm to suit different pipe configurations.

More than a component: a real process improvement

In pneumatic conveying, performance does not depend only on major equipment.

It depends on every detail.

A poor connection can cause:

  • Pressure losses
  • Product build-up
  • Increased wear
  • Frequent maintenance interventions

An optimized connection ensures:

  • Continuous flow
  • Reduced maintenance
  • Greater system stability
