Pyplok® mechanically attached non-welded fittings solve many issues encountered when joining pipe/tubes together, particularly for water mist and fire suppression/protection systems.

Applications in Water Mist and Fire Protection

Water-based fire suppression systems, particularly water mist technology, use high-pressure piping. Pyplok® non-welded, cold-swaged systems offer safety, cleanliness, and durability under high pressures while also eliminating nozzle clogging.

Pyplok® pipe fittings are approved for use in water mist systems in buildings, museums, tunnels, marine vessels and offshore assets, and any facilities that require such systems to protect lives and property from fire.

Examples of Pyplok® Integration in Fire Suppression Systems 

Madrid City Hall

In Madrid City Hall, Pyplok® fittings were used to connect over 25,000 feet of water mist piping and mist nozzles connections for upgrades to its fire suppression system.

Hugh L. Carey Tunnel (also known as Brooklyn Battery Tunnel)

Over 4,000 Pyplok® fittings, including couplings, 90° elbows, and custom reducer tees, all suitable for Fogtec proprietary nozzles, were installed on over 12,000 feet of pipe. The Pyplok® team provided on-time delivery, system installation, and training, ensuring successful project execution, all during the height of COVID-19.

How It Works

Installing Pyplok® is fast, clean, and safe, and the results are built to withstand high pressures.

Pyplok® is a 360° radial swaged non-welded fitting which permanently connects pipe and tube for a cold, leak-free connection. The system is fast, reliable, and tamper proof. A hydraulically powered compression tool swages the fitting over pipe/tube, plastically deforming the fitting in seconds.

Pipe Fittings for Fire Suppression and Protection Systems

Pyplok® supplies all commonly used types of pipe fittings suitable for NPS pipes, OD tubes, and metric tubes.

Pyplok® fittings come in all standard configurations (straights, 45° and 90° elbows, adapters, tees, reducers, and flanged ends) and are tested to handle pressures up to 10,000 PSI/ 690 bar.

Configurations provide permanent ends or a combination of permanent and separable ends. Separable ends include ANSI, SAE, and ISO Flanged, as well as JIC 37°, ORFS, NPT, BSPP, and DIN 24° fittings. Pyplok manufactures custom distribution blocks with two-port and four-port designs specifically for the fire mist systems. 

Pyplok® fittings are available in carbon steel, duplex and super duplex stainless steel, and copper nickel (CuNi).
