At SUTEIN, we offer a comprehensive range of HS Umformtechnik pipe couplings, designed to provide secure, leak-tight connections between pipe sections in pneumatic conveying systems for bulk solids.
Our range includes solutions for different operating conditions: pipe couplings for pressure conveying, vacuum and suction conveying systems, and stainless steel pipe couplings, available in various diameters, lengths and seal materials.
Manufactured from high-quality materials and designed for demanding industrial environments, HS pipe couplings enable welding-free installation, reducing assembly time while facilitating dismantling, maintenance and component reuse.
Selecting the right pipe coupling helps maintain system tightness, prevent pressure losses and ensure reliable pneumatic conveying operation. Our technical team will help you choose the most suitable solution based on pipe diameter, operating pressure or vacuum, conveyed material, temperature and specific installation requirements.
DVK-HD pipe couplings are designed to provide secure, leak-tight connections between pipe sections in pressure pneumatic conveying systems, where connections must withstand demanding operating conditions without compromising system tightness.
They provide a robust, secure and easy-to-install connection between pipe sections, reducing the risk of leaks, misalignment and process downtime.
Enhanced protection against foreign-body contamination in food processing applications
HS Umformtechnik DVK-HD pipe couplings are now available with blue metal-detectable silicone seals, offering an additional safety feature for pneumatic conveying systems in the food industry.
This solution provides two complementary methods for identifying potential seal fragments:
Metal detection: The specially formulated silicone enables potential fragments to be identified by suitably configured metal detection systems.
Visual identification: The blue colour, rarely found in food products, makes potential fragments easier to identify during inspection and quality control.
This configuration provides an additional preventive measure against foreign-body contamination, helping to strengthen food safety and quality control procedures.
DVK6 pipe couplings are specifically designed for connecting pipe sections in vacuum and suction pneumatic conveying systems, providing a lightweight, reliable and adaptable solution.
They enable secure, welding-free connections, facilitating installation, dismantling and maintenance.
Manufactured from AISI 304 stainless steel, these pipe couplings are designed for pneumatic conveying systems for bulk solids where high resistance to corrosion, abrasion and demanding operating conditions is required.
They provide robust, secure connections between pipe sections, helping to prevent leaks, pressure losses and misalignment while ensuring reliable system operation.
HS pipe couplings are part of a complete solution for pneumatic conveying systems. Explore our range of pipe bends, branches and reducers for pneumatic conveying, available in different materials and configurations to meet the requirements of each installation.
To select the right pipe coupling, it is important to consider the pipe diameter, pressure or vacuum conditions, operating temperature, compatibility of the seal material with the conveyed product, and maintenance requirements.
For a more detailed explanation of these criteria, read our guide How to choose the right pipe coupling for a pneumatic conveying system, where we explore the different options available and the most common mistakes to avoid.
Our technical team can help you choose the most suitable solution for your application.
Yes. HS Umformtechnik pipe couplings provide detachable connections between pipe sections without welding. This reduces installation time and facilitates dismantling, maintenance and component reuse.
The choice of seal material depends on factors such as the conveyed product, operating temperature and specific installation requirements. Depending on the coupling model, different materials are available, including NBR, EPDM, silicone, Viton and natural rubber.
For food processing applications, DVK-HD couplings can also be supplied with blue metal-detectable silicone seals, designed to facilitate the identification of potential seal fragments.
Stainless steel pipe couplings are particularly suitable for pneumatic conveying systems exposed to corrosive environments or demanding operating conditions where durability and resistance to corrosion are essential.
HS Umformtechnik couplings manufactured from AISI 304 stainless steel also offer high abrasion resistance and can be supplied with different seal materials according to the application requirements.
Yes. HS Umformtechnik offers pipe couplings with different seal materials and configurations for food processing applications. Certain models are available with seals suitable for food contact and options that comply with requirements such as FDA regulations and Regulation (EC) No 1935/2004.
In addition, DVK-HD couplings can be fitted with blue metal-detectable silicone seals, which facilitate the identification of potential seal fragments through metal detection systems and visual inspection, helping to reduce the risk of foreign-body contamination.
The appropriate seal must be selected according to the conveyed product, operating conditions and specific requirements of each installation.
Our technical team will help you select the most suitable HS Umformtechnik pipe coupling based on pipe diameter, operating pressure or vacuum, conveyed material, temperature and the specific requirements of your installation.
