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.

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.

At SUTEIN, we are expanding our range of solutions by incorporating Filcoflex, a manufacturer specialized in flexible connections for bulk solids handling and industrial processes.

This partnership allows us to offer our clients advanced solutions to improve the tightness, safety, and reliability of their installations, particularly in applications such as pneumatic conveying, weighing systems, and Big Bag discharge.

You can explore the full range of solutions here: Filcoflex flexible connections.

Filcoflex is a Netherlands-based company and an international leader in the design and manufacturing of custom-made flexible connections for industries such as food, pharmaceutical, and chemical.

Their portfolio includes sleeves, bellows, and flexible connection systems designed to adapt to each installation, using certified materials and solutions that meet the most demanding hygiene and safety requirements.

Unlike standard solutions, Filcoflex works with a fully customized approach, designing each connection according to the process, the product, and the operating conditions.

From February 10 to 12, we participated in Exposolidos 2026, Spain’s leading trade fair for solids handling, pneumatic conveying, and industrial process technology.

For SUTEIN, it was more than just a trade show.
It was an opportunity to listen first-hand to engineering firms, plant managers, and maintenance teams who work every day to improve the reliability and efficiency of their facilities.

And if one thing became clear, it is that pneumatic conveying of solids remains a critical point in many industrial plants.

2025 has been a milestone year for SUTEIN. Not just for achieving a record turnover, but for doing so without losing sight of what defines us: closeness, agility, high-quality technical service, and a philosophy focused on delivering real value to our clients.

We’ve maintained the trust of our customers, expanded our portfolio, reinforced our stock of represented brands, and strengthened our own line of products STN VALVES. All thanks to a committed team that continues to grow in experience, dedication, and responsiveness.

Even from the projects we didn’t win, we learned. And that, too, is progress.

Tangible growth, tailored solutions

During our visit, FHT showed us its new production hall and the major upgrades to its factory.
This expansion represents not only a milestone for the brand but also a valuable opportunity for us and our customers.

Thanks to this growth, FHT can now manufacture an even broader range of valves — in both size and design variety.
This enables greater precision in meeting the specific requirements of each project, from standard processes to highly demanding applications.

Whether in the chemical, pharmaceutical, food or energy industries, having a brand capable of designing valves that integrate perfectly into each system provides a key competitive advantage.
