Air transport piping coupling "Eurac Coupling"

Air transport piping coupling "Eurac Coupling"

Cheaper than flange connections! Compression coupling for air transport piping.

The EURAC coupling is a piping compression coupling used in approximately 600,000 units annually across 60 countries worldwide. It was developed and launched by the French company STIF as an alternative to flange connections for piping installation. It offers a product lineup suitable for low to high pressure, low and high concentration air transport, as well as for pumping and suction transport. ■ No welding required, and more cost-effective than flange connections Compared to flange connections, it reduces costs by about 50% in parts, eliminates the need for welding work, and significantly lowers the costs associated with bolt fastening. *Note: "Welding fumes" generated from processes such as metal arc welding have been added to the list of specified chemical substances and will be enforced from April 1, 2021. Reducing welding work is a very effective solution. ■ Easy installation Simply fit the coupling onto the connecting piping and tighten it with a torque wrench, aligning the center of the coupling with the connection point of the piping. 【Features】 ■ High pressure resistance and long lifespan ■ Easy installation ■ More cost-effective than flange connections ■ Space-saving for parallel piping ■ A wide variety of options to suit different applications *For more details, please refer to the PDF document or feel free to contact us.
