Stopper press fittings 22

Product detailed description

Press stoppers are essential components in closed pressurised systems where pipe ends require secure and leak-free sealing. This includes central heating systems, fire suppression installations, and industrial air or gas distribution. Installers and technicians working in commercial and industrial buildings often use these fittings to terminate or isolate sections of pipe without the need for welding or threading. The IVC51.22 model is specifically designed for 22 mm steel pipe and is used in applications where a PN 16 rating is required. It is suitable for both cold and hot media, including water, dry air, and inert gases, and is commonly found in HVAC ductwork, solar system piping, and refrigeration systems.

Proper selection and installation of press stoppers are critical to system integrity. The IVC51.22 is intended for use in systems with operating temperatures between -20 °C and +85 °C, with a maximum allowable temperature of +120 °C. It is not certified for potable water, so alternative fittings must be used in drinking water applications. The fitting is made of carbon galvanized steel, which provides resistance to mechanical damage and corrosion in non-drinking water environments. It is compatible with Type M jaws for press fitting, ensuring a secure and repeatable connection.

The technical parameters define the operating limits and compatibility of the IVC51.22. The working temperature range ensures the fitting can be used in both cold and hot systems, while the pressure rating of 16 bar allows for use in high-pressure environments. These values are essential for sizing and selecting the correct fitting for a given application, particularly in systems where thermal expansion or pressure surges may occur.

Installation and connection

The IVC51.22 press stopper is installed using a press tool with Type M jaws. The pipe must be cut cleanly and deburred before fitting. The stopper is inserted into the pipe end and pressed using the appropriate tooling. The molding indicator on the fitting confirms a successful press. The connection size is 22 mm, and the fitting is designed for use with carbon steel pipe of the same diameter. During installation, the installer must ensure the pipe is straight and free from debris to avoid misalignment or incomplete pressing. Common mistakes include using incorrect jaw types or failing to check the molding indicator after pressing.

Compatibility and accessories

The IVC51.22 is compatible with other IVAR press fittings and Type M jaw tools. It is not suitable for use with other jaw types or systems requiring potable water certification. No additional accessories are required for installation, but a press tool and suitable jaws must be available. The fitting is supplied in packs of 10 units and is intended for use with carbon galvanized steel pipe. No related products are available for this model.

Technical background for designers

The IVC51.22 operates on the principle of mechanical deformation, where the press tool compresses the fitting around the pipe to form a secure joint. The material, carbon galvanized steel, offers good resistance to corrosion and mechanical stress in non-drinking water environments. The fitting is designed for use in closed pressurised systems and is suitable for integration with other press fittings and valves. The service life and efficiency of the fitting depend on correct installation, proper system pressure and temperature, and the absence of aggressive media that could accelerate corrosion.

Service and operation

No regular maintenance is required for the IVC51.22 during normal operation. However, periodic visual inspections are recommended to check for signs of mechanical damage, corrosion, or leaks. The molding indicator should be verified during installation to ensure a secure connection. If the fitting is used in a high-vibration environment, additional support may be necessary to prevent stress on the joint. There are no specified service intervals for this fitting.

Frequently asked questions

Can the IVC51.22 be used in potable water systems?
No, the IVC51.22 is not certified for use with drinking water. A different fitting must be selected for potable water applications.

What type of press tool is required for installation?
The IVC51.22 requires a press tool with Type M jaws. Using other jaw types may result in an incomplete or incorrect press.

Can the fitting be used with copper or stainless steel pipe?
No, the IVC51.22 is designed for use with carbon galvanized steel pipe only. Using other materials may compromise the integrity of the joint.

Is the IVC51.22 suitable for high-temperature applications?
Yes, the fitting is suitable for temperatures up to +120 °C, but it should not be used in applications exceeding this limit.
