REDUCED PIPE COUPLING (No.1R)

The lead-free polymer safety fittings are the result of continuous technical innovation and research. This new range was designed and patented to reach the highest safety standards regarding the connection of in-wall multi-layer pipe installations.

The fittings are made from PPSU (polyphenylsulfone) which is a high-performance polymer that has excellent impact and chemical resistance.  It is commonly used in the fields of avionics due to its lightweight nature and flame-proof characteristics, and in medical applications such as human joint replacements due to its high impact strength and compatibility with human tissue.  The material is also lead-free, making it the safest choice for drinking water applications.

Jointing

Patented tools flare the pipe around the fitting to maintain precise inside diameters of the fittings, reducing pressure drops throughout the fittings.  The pipe is then locked on the fitting by a tight collar/cap connection and can be unlocked and used again.

The idea to develop the safety fittings came from the decision to increase the flow – consequently decreasing pressure drops, friction, noise and enabling the reduction of pipe sizes in some cases. This has been achieved by making a greater diameter socket on the pipe head for the connection.

The project has been carried out step by step, going through all necessary tests and paying great attention to reliability factors for its in-wall piping use. The production of the safety fittings began only after receiving certifications from international authorities for the whole range, and its dedicated accessories.

The socket on the pipe head is made by a special patented tool that ensures a quick, reliable, and safe connection.

Description

In addition to the multilayer pipeline systems outlined, Aquatechnik also provides a wide range of fittings made of polymeric materials and metal that can be used to create connections with the pipeline systems provided by the company.
The common feature among the various ranges of fittings that the “safety” system uses is the particular geometry of the fittings which has clear advantages in terms of fluid flow, ease of processing, and levels of safety.
The unique feature of this system is that it maintains the same flow cross-section at the pipe/fitting transition point, compared to traditional methods which show a significant reduction in flow.
This innovative principle allows a considerable reduction of pressure drops in a simple, rapid, and reliable way, which not only favors energy savings due to reduced pump energy usage, but also leads to a reduction in associated pipeline noise.
The joint system between the pipe and fitting can thus be characterized by a number of fundamental factors:
¢ expansion of the pipe (flaring):
made with specific patented tooling, it allows simple,
rapid and safe coupling of pipe and fitting;
¢ the pipe/fitting joint system:
the pipe is positioned and secured at the fitting using
a cap that eliminates any movement;
¢ the anti-unscrewing system:
the cap is locked in position with a locking spanner
produced by Aquatechnik, which ensures a secure joint.
However, if required, this can be unlocked by using the
locking spanner, allowing easy removal of the fitting.
