Arch 90°, 28 x 28

Product detailed description

This 90° long radius elbow is commonly used in closed heating systems, fire suppression circuits, industrial air and gas lines, and solar thermal installations. It is particularly suited for press-fit systems requiring high mechanical stability and tight sealing without the need for welding or threading. The elbow is typically installed in mechanical rooms, under floors, or within wall cavities where space allows for a longer radius turn. Installers working in commercial and industrial HVAC, plumbing and fire protection sectors will find this component essential for directional changes in press-fitted steel piping.

The elbow is made from carbon galvanized steel and is compatible with Type M jaws for press-fit installation. It is not certified for potable water and should not be used in systems carrying drinking water. Its design supports a wide range of operating conditions and media types, making it suitable for environments where dry air, inert gases or non-potable water are transported under pressure.

Installation and connection

To install the IVAR IVC70.28, ensure the pipe ends are clean and free of burrs. Use a press tool with Type M jaws to compress the fitting onto the pipe. Check the molding indicator to confirm the joint is fully formed. Avoid over-pressing, which can damage the fitting. Verify the alignment of the elbow before pressing to prevent misalignment in the system. Common installation errors include using incorrect jaw types, failing to align the fitting properly, or neglecting to check the molding indicator after pressing.

Compatibility and accessories

This elbow is compatible with other IVAR press-fit components and systems using carbon steel piping. It is intended for use with press tools certified for Type M jaws. No additional surface coatings or limiting agents are required for installation. For larger systems, additional fittings such as couplings, tees and valves from the same range may be needed to complete the layout.

Technical background for designers

The elbow operates on the principle of mechanical compression, forming a sealed joint between the pipe and fitting when pressed. The carbon galvanized steel offers resistance to corrosion and mechanical damage, making it suitable for both indoor and industrial environments. The elbow is designed for integration into closed pressurized systems, where it maintains structural integrity under varying thermal expansion and contraction. The service life is influenced by the quality of the press-fit joint, the absence of vibration stress, and the chemical nature of the transported medium. The operating temperature range ensures flexibility for both heating and cooling applications.

Service and operation

Routine inspection should focus on the integrity of the press-fit joints and the absence of leaks. Check the molding indicator during installation to confirm a secure fit. No specific service intervals are defined for this component. If a leak is suspected, isolate the affected section and inspect the joint for signs of improper pressing or damage. Replace the fitting if necessary.

Frequently asked questions

Can the IVAR IVC70.28 be used in solar thermal systems?
Yes, the elbow is suitable for solar systems provided the operating conditions remain within the specified temperature and pressure limits.

Is the fitting compatible with inert gas systems?
Yes, it is suitable for systems transporting dry air or inert gases under pressure, as long as the media does not react with the material of the fitting.

Can this elbow be used in fire suppression systems?
Yes, it is appropriate for fire water supply ductwork and sprinkler systems that are permanently water-filled.

What tools are required for installation?
A press tool with Type M jaws is required for proper installation. Ensure the tool is calibrated and maintained according to the manufacturer’s guidelines.
