IVAR.IVN70,IVN73,IVN74,IVN75 - fitted bend

This category includes IVAR.IVN70, IVN73, IVN74, and IVN75 stainless steel fitted bends available in 15°, 30°, 45°, and 90° configurations. These bends are designed for use in heating systems, plumbing installations, sprinkler systems, compressed air systems, solar systems, and industrial applications. The fittings are manufactured from 1.4404 (AISI 316L) stainless steel and operate within a temperature range of -20°C to +85°C, with a maximum of +120°C. They are suitable for PN16 pressure ratings and are intended for tight sealing when properly crimped up to 54 mm.

These bends are ideal for applications requiring corrosion resistance and long-term durability in aggressive environments. They are commonly used in closed-loop systems where high reliability and minimal maintenance are essential. The bends are sized to match the internal diameter of the connected pipes and are available in a range of sizes from 15 mm up to 108 mm.

How to choose

• Select the correct angle (15°, 30°, 45°, or 90°) based on the required directional change in the system layout.
• Match the nominal diameter (N) of the bend to the internal diameter of the connected pipes for proper hydraulic performance.
• Ensure compatibility with the system pressure rating (PN16) and operating temperature range (-20°C to +85°C, max +120°C).
• Verify that the material (1.4404 stainless steel) is suitable for the specific application environment, particularly in aggressive or corrosive conditions.
• Confirm that the bend is used with a crimping tool and has an indicator for correct crimping up to 54 mm to ensure a leak-tight seal.

Frequently asked questions

What is the maximum operating temperature of these bends?
The maximum operating temperature is +120°C, with a standard operating range of -20°C to +85°C.

Can these bends be used in solar systems?
Yes, these bends are suitable for solar systems due to their high corrosion resistance and ability to handle elevated temperatures.

Why is crimping important for these bends?
Crimping ensures a tight seal and proper connection. The bends must be crimped up to 54 mm with an indicator to prevent leakage and ensure system integrity.
