Universal Drilling Strap – Reliable Connection to Existing Infrastructure
This drilling strap, made of durable spheroidal graphite cast iron, is a key tool for connecting new water supply connections to existing networks. It enables safe and efficient execution of so-called "hot taps" – drilling a hole in a pressurized pipeline without the need to shut it off. This solution saves time and minimizes disruption to water supply. The strap is designed for use on steel and cast iron pipes, making it a versatile element in every installer's equipment.
Design and Application
The strap is characterized by a compact design and easy installation thanks to the flexible stainless steel strap. The clamping angle has been optimized to ensure maximum clamping force, and the nuts on spherical (version 3500) or cylindrical (version 3510) washers guarantee connection stability. The saddle gasket, precisely matched to the pipe radius, ensures tightness, and the rubber ring protects the internal thread from corrosion and scale build-up. The strap is available with an internal thread (1/4 inch) and a flanged outlet version.
Applications:
- Connecting new water supply connections to existing networks.
- Performing hot taps in steel and cast iron pipes under pressure.
- Domestic installations and water networks with a maximum pressure of PN16.
- Installation on pipes of various diameters – from DN 50 to DN 600 (depending on the model).
Features and Benefits for Professionals and End Users
- Strength and Durability: The body made of spheroidal graphite cast iron (GJS-spheroidal cast iron series 3500) provides resistance to mechanical damage and corrosion, guaranteeing long-term use.
- Safety: The ability to drill pipes under pressure eliminates the risk of water shut-off for users during installation.
- Versatility: The strap is compatible with both steel and cast iron pipes, increasing its range of applications.
- Tightness: The precisely matched saddle gasket and rubber ring ensure a tight connection, minimizing the risk of leaks.
- GSK Certificate: Confirms the anti-corrosion protection of the strap, which translates to its longevity and reliability.
- Easy Installation: The flexible strap makes it easy to fit the strap to pipes of different diameters, and the design ensures quick and intuitive installation.
- Time Saving: Performing the connection without the need to shut off the water significantly shortens the duration of installation work.
Thanks to these features, the Hawle strap is an investment in a solid and safe connection that will last for years of trouble-free operation.
