FORGOT YOUR DETAILS?

steelPRES is the Pressfitting system by Raccorderie Metalliche in carbon steel developed for any closed circuit applications where it is not necessary to use stainless steel, which it is to be considered a valuable cost-effective alternative.

 

steelPRES material E195 carbon steel.

 

The steelPRES product range consists of pipes, fittings and installation materials. The range of steelPRES pipes and fttiings is approved by many certified international institutions. 9 certificaions, obtained by RM on the steelPRES product, confirm quality and reliability for applications such as heating, cooling, compressed air and fire protection.

The range of pipes in carbon steel according to the UNI EN 10305-3 standard consists of welded, bordered and calibrated pipes in three different configurations:

• Externally galvanized.

• Externally galvanized and covered in polypropylene (1 mm thick).

• Internally and externally galvanised in sendzimir.

Fittings are made in unbounded E195 steel, galvanized with a zinc layer (to increase protection against external corrosion) and fttted with a “M-shaped” profile toroidal chamber, optimized thanks the 20 year research experience. Any fttiing hs factory mounted, with an EPDM O-Ring, with a patented profile at the end of production.

Pipes and joints are available from Ø12 to 108 mm.

Where to use steelPRES?

Products and services are developed to solve at best any installation problem and issue, aiming at quality, safety and speed.

Carbon steel is the best solution where stainless steel features are not demanded and where a cost-effective product is required. The use of steelPRES by Raccorderie Metalliche is suitable to make civil and industrial plumbing and sanitation closed loops for heating and cooling, wet fire-fighting sprinklers and compressed air installations. O-Rings can be used between -20 to +120°C, minimum pressure 16bar providing for quality and safety as well.

Pressfitting Systems

The junction connection of RACCORDERIE METALLICHE press fttiing systems is with “M” contour. During the pressing process a deformation takes place on two planes. The first plane creates a permanent connection and provides mechanical strength through the mechanical deformation of the press fitting and the pipe. On the second plane the seal ring is deformed in its cross secoon and through its elastic properties creates the permanently tight joint.

Sealing ring profile (o-ring)

Traditional press fttiing systems use round sealing rings, which can easily be damaged by careless fning. RM on the other hand uses a patented sealing ring with a lenticular profile which fits the press crimp groove. This provides the following advantages:

•    A 20% enlargement of the sealing surface area;

•    Major reduction of the risk of the sealing ring being pressed out or damaged;

•    Flit makes the pipes insertion easier
