The expert answers

What do you mean by homologated pressfitting system?

Homologated pressfiting is the permanent junction between pipes and fittings through an assembly process that is certain, defined and verified by a product certification Body.

What types of installations may be made with pressfitting systems? Who authorizes industrial uses?

The pressfitting is a unique system to make various installations within the same sector, either civil or industrial. It was created for typical applications, such as hot and cold water (heating, drinking water, cooling, etc.).

What are the advantages of pressfitting systems vis à vis the traditional junction systems (threaded, brazed, welded, etc.)?

Compared with the traditional junction systems, the pressfitting systems are installed more rapidly, thereby saving considerable assembly time: they are simpler and more convenient, requiring only compliance with the correct installation techniques, while ensuring proper seal.

What are the materials available for pressfitting systems? Which diameters are available?

The pressfitting systems manufactured in Italy

What are the dimensional characteristics of the O-Rings assembled on pressfitting joints?

All joints have an O-Ring assembled, with the typical profile, a patented lens-shaped section. The special O-Ring sold individually also have the same profile.

What type of stapling machines and jaws can be used to staple the pressfitting systems?

The pressfitting systems were homologated with KLAUKE and NOVOPRESS stapling machines.

What is the difference between raw and annealed pipe?

The difference between a raw and an annealed pipe consists in a stress relieving treatment, which confers greater malleability to the basic material. Annealed pipes are more bendable than raw pipes.

What is the Oversize?

The Oversize is a new pressfitting range, made of AISI 316L stainless steel available in 139 and 168mm diameters. The Oversize range can be pressed with the dedicated machine Novopress ACO401//403 and dedicated chains, specifically manufactured for special, high-pressure applications up to the size 168,3 mm.

What are the inoxPRES Steam and the inoxPRES Silicone Free?

The Steam (ST) range is a new pressfitting range, made of STEAM stainless steel with a white O-Ring, designed for saturated vapour installations with a maximum temperature of 165°C and maximum pressure of 7 bar.

What are Hydro-shaped Ts?

The Hydro-shaped Ts are T fittings in carbon steel that thanks to hydroforming are not welded.
