In any profession, minimising human error is the key to success. In fire protection piping installations, this is especially important, as even a slight mistake can have disastrous results.
Using Surepress Pressfit fittings is one way to help reduce the possibility of human error. Their European design has proven to be highly reliable and efficient.
Here, we will discuss what Surepress Pressfit fittings are, how they bring the carbon steel pipes together, and why they are a valuable tool in the fire protection piping engineer’s arsenal.
The SurePress Pressfit carbon steel fire protection piping system comprises of several key components, each specifically designed to work in tandem with one another:
An innovatively designed O-ring at each end of the Pressfit fittings is compressed in a toroidal chamber before creating a hermetic seal, which makes the fitting airtight. These O-rings are available in various shapes and sizes, and can be used for flanged and threaded connections. Thanks to their synthetic material composition, they’re durable enough to last with normal use and in harsh conditions all year round.
- Press-Check Sleeves
With a new fire protection piping system, any leaks are attributable to just one reason: the incorrect or failed pressing of joints. In traditional methods of testing, it’s difficult for installers to find possible weak spots. But now, Surepress provides a solution to easily identify any unpressed joint easily. It is a visual system called a ‘press-check sleeve’: a thin and eye-catching coloured film applied externally to the joints. Once pressed, the indicator falls off, and the installer can see if any fittings have been missed.
- Carbon Steel Piping
The pipes are lightweight, thin-walled tubes that installers can simply cut with plumbing tube cutters, push them together, and then crimp them using a battery-operated tool. The zinc coating has electrochemical protection, meaning if the zinc coating is scratched, there is a film that bonds over that part, protecting the zinc from corrosion. Carbon steel also has excellent abrasive hardness, producing a strong and resistant facing.
