Shorter offset 15 x 15

Product detailed description

Short offset fittings are essential components in the installation of closed pressurized systems, including central heating, fire water, and industrial air conditioning. These fittings allow for directional changes in piping without the need for welding or threading, which reduces installation time and improves system integrity. In commercial and industrial buildings, such fittings are commonly used in tight spaces where traditional bends or elbows are impractical. The IVAR IVC77.15 is specifically designed for compact installations where space constraints require minimal offset lengths.

Its use in systems with pressurized dry air, inert gases, and permanently watered sprinkler systems requires fittings that can maintain structural integrity under varying conditions. The IVC77.15 is suitable for both heating and cooling applications, making it a versatile option for a range of system designs. The fitting’s galvanized steel construction provides resistance to mechanical damage and ensures long-term durability in environments with potential exposure to moisture and temperature fluctuations.

The operating temperature range of -20°C to +120°C ensures suitability for both cold and hot media, while the nominal pressure rating of PN 16 allows for operation under pressures up to 16 bar. These parameters are critical for proper sizing and selection in pressurized systems where pressure and temperature fluctuations are common. The maximum temperature of +120°C is particularly important for heating applications, where the fitting must maintain its integrity under sustained heat exposure.

Installation and connection

The IVAR IVC77.15 is installed using press-fit technology, which requires the use of Type M jaws for proper compression. The fitting has a nominal size of 15 x 15 mm and is designed for direct connection to pipes of the same diameter. During installation, it is essential to ensure that the press-fit indicator is fully engaged and that the fitting is not over-pressed, as this can lead to leaks or structural failure. The maximum pressing depth should not exceed 54 mm. Common installation mistakes include using incorrect jaw types or failing to verify the press-fit indicator, both of which can compromise the seal and system performance.

Compatibility and accessories

The IVC77.15 is compatible with other IVAR press-fit fittings and pipes in the same size range. It is designed for use in closed pressurized systems and should be combined with appropriate pipes and fittings to ensure system integrity. No additional surface coatings or limiting agents are required, but it is important to ensure that all components are from the same press-fit system to maintain compatibility. No specific accessories are required for installation, but the use of a calibrated pressing tool is essential for achieving a secure connection.

Technical background for designers

The IVAR IVC77.15 operates on the principle of mechanical compression, where the fitting is pressed onto the pipe to create a leak-tight seal. The galvanized steel material provides resistance to corrosion and mechanical stress, making it suitable for both indoor and industrial environments. The fitting is designed to integrate into systems that require directional changes without the use of traditional joints, which can be difficult to maintain over time. The service life and efficiency of the fitting are influenced by the quality of the pressing process, the condition of the pipe ends, and the stability of the operating conditions within the system.

Service and operation

No specific service intervals are required for the IVC77.15 during normal operation. However, it is important to periodically inspect the press-fit connections for signs of wear, leakage, or mechanical damage. In high-pressure or high-temperature environments, more frequent inspections may be necessary to ensure continued system performance. The absence of surface coatings or limiting agents means that the fitting does not require special maintenance procedures, but it should be replaced if any signs of leakage or deformation are observed.

Frequently asked questions

Can the IVC77.15 be used in fire suppression systems?
Yes, the fitting is suitable for permanently watered sprinkler systems and fire water piping, provided the operating conditions remain within the specified pressure and temperature limits.

Is the IVC77.15 compatible with other press-fit systems?
It is specifically designed for use with IVAR press-fit components and may not be compatible with fittings from other manufacturers due to differences in pressing technology and jaw types.

Can the IVC77.15 be used for dry air applications?
Yes, the fitting is suitable for pressure dry air and inert gas systems, as long as the operating pressure does not exceed 16 bar and the temperature remains within the specified range.

What is the maximum pressing depth for the IVC77.15?
The maximum pressing depth is 54 mm. Exceeding this depth may result in an incomplete seal or damage to the fitting.
