Arch 90°, 88.9 x 88.9

Product detailed description

This 90° long radius elbow is commonly used in closed heating systems, fire suppression systems, and industrial air or gas piping. It is suitable for installations where smooth directional changes are required to reduce turbulence and pressure loss. The elbow is often found in residential and commercial buildings, including central heating ducts, refrigeration systems, and air-conditioning ducts. Installers typically use it in press-fit systems where welding or threaded joints are not preferred due to time or safety constraints.

The elbow is designed for use in press-fit systems, where it connects to other components using Type M jaws. It is suitable for a wide range of applications, including central heating, cold water, refrigeration, fire suppression, and air-conditioning systems. The elbow is not certified for drinking water use and should not be installed in systems where potable water is transported.

Technical parameters

Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	2.202 kg
Code	IVC70.89
Brand	IVAR

The elbow is rated for a maximum operating pressure of 16 bar and is suitable for temperatures ranging from -20°C to +120°C. These parameters are essential for determining the suitability of the elbow for specific applications, particularly in high-pressure or temperature-sensitive environments. The PN 16 rating ensures compatibility with other components in the same pressure class.Installation and connection The elbow is installed using a press-fit tool compatible with Type M jaws. The connection is made by inserting the pipe into the fitting and pressing it with the appropriate tool to form a secure joint. The elbow has a nominal diameter of 88.9 mm at both ends, with a long radius bend that allows for smoother flow and reduced resistance. During installation, it is important to ensure that the press tool is correctly aligned and that the molding indicator is fully engaged to confirm a successful connection. Common installation mistakes include using the wrong jaw type or failing to verify the molding indicator, both of which can lead to leaks or weak joints.Compatibility and accessories The elbow is compatible with other components in the IVAR.IVC70 series and is designed to work with press-fit systems using Type M jaws. It is typically used in conjunction with straight pipes, other elbows, and tees of the same nominal diameter. No additional surface coatings or limiting agents are required for installation. However, it is important to ensure that all components in the system are from the same manufacturer or compatible with the same press-fit system to avoid compatibility issues.Technical background for designers The elbow is made from carbon galvanized steel, which provides good resistance to corrosion and mechanical damage. The long radius bend reduces flow resistance and minimizes pressure loss, making it suitable for systems where efficiency is important. The elbow is designed for use in closed pressurized systems and is suitable for a wide range of media, including water, dry air, inert gases, and industrial fluids. The operating temperature range and pressure rating are key factors in determining the elbow's suitability for specific applications. The material and design contribute to the elbow's durability and long service life, provided that it is installed correctly and used within its specified parameters.Service and operation The elbow requires minimal maintenance due to its durable construction and press-fit design. No regular service intervals are required, and the elbow does not need to be inspected or replaced unless there is visible damage or a leak. During operation, it is important to check for any signs of wear, corrosion, or deformation, particularly in high-pressure or high-temperature environments. If a leak is suspected, the joint should be inspected and re-pressed if necessary. The elbow's resistance to mechanical damage ensures that it remains functional for extended periods with little to no maintenance.Frequently asked questions

Can the IVAR IVC70.89 be connected to other IVAR press-fit components?
Yes, the elbow is compatible with other components in the IVAR.IVC70 series and is designed for use with Type M jaws. It can be connected to straight pipes, tees, and other elbows of the same nominal diameter.
