Raccorderie Metalliche and cooling plants

Raccorderie Metalliche paid the due attention to cooling plant applications, developing its Pressfitting product in 4 different materials to provide installers and designers the best possible solutions to any requirement. Open or closed loop, in domestic or aggressive environments, as in case of some industrial processes, the Pressfitting system by Raccorderie Metalliche always provides for the most suitable solution.

It is the range of unbonded steel Pressfitting pipes and fittings available from Ø12 to Ø108 mm. Fittings are made in E195 (n. 1.0034) and galvanised.

For closed loop heating plants, a single range of products, externally galvanized in E220 (n. 1.0215). The pipes are longitudinally welded, bordered and calibrated. steelPRES by Raccorderie Metalliche matched with an externally galvanized pipe is rightfully used in closed loops, civil and industrial heating plants.   The pipes covered in polypropylene is used in case the temperature range difference between the plant and the surrounding environment leads to condensation build-up. It is then wise to use a pipe with a polypropylene layer to protect the metal. A further protection consists of covering of the fittings with a butyl bandage. Raccorderie Metalliche as to comply with the requirement to thermally insulate the plants, developed isoPRES that is a new range of customized insulating materials for the pressfitting and available from Ø15 to Ø54 mm.   steelPRES fittings are pre-fitted EPDM O-Rings, a compound providing for the best possible performances:  PM16 maximum pressure, temperature ranging between -20/+120° C and quality in time.   The affordable price and the certified product quality by many international institutions make steelPRES the best possible product solution for a similar application.

The best proposal matching features of stainless steel and benefits of the Pressfitting system.​

Raccorderie Metalliche developed its own bonded CrNiMo 1.4404 (AISI 316L) steel products,  Ø15 to Ø168 mm. As to supply designers and installers the best possible solution, inoxPRES fittings can be used with 5 different ranges of stainless steel pipes:
  • complete range in 1.4404 (AISI 316L) raw steel, available Ø15 to Ø168 mm
  • complete range in 1.4404 (AISI 316L)annealed steel, available Ø15 to Ø108 mm
  • complete range in 1.4521 (AISI 444) steel, available Ø15 to Ø54 mm
  • complete range in 1.4301 (AISI 304) steel, available Ø15 to Ø108 mm
  • complete range in 1.4301 (AISI 304) steel, reduced thickness, available Ø15 to Ø108 mm

The pipes are longitudinally welded, bordered and calibrated. Stainless steel high resistance to corrosion makes inoxPRES system by Raccorderie Metalliche the most suitable solution for thermal solar plants and circuits. At the civil and industrial level as well where processes and processing  can lead to aggressive and corrosive environments, such a material turns out to be the most suitable solution.
All inoxPRES fittings are pre-fitted EPDM O-Ring,  developed to be used  providing for the highest possible performances: maximum pressure PN16, temperature ranges -20/+220° C and quality in time.
The 22 issued certifications from the most important certification bodies prove the high quality of inoxPRES by Raccorderie Metalliche, offering designers and installers an easy-to-use, reliable and safe solution in case of the most difficult and complex applications as well.
