Nut for solar pipe - set DN25

Product detailed description

Solar thermal installations require precise and durable components to ensure long-term performance. In residential and commercial solar heating systems, the termination of stainless steel pipes must be handled with care to maintain system integrity and prevent leaks. Installers working with solar collectors, heat exchangers, and circulation loops often encounter the need to terminate and connect pipes to fittings, valves, or collectors. This set provides a reliable solution for such tasks, particularly in systems where stainless steel piping is deformed to fit the required geometry.

Correct termination of solar piping is essential for maintaining hydraulic balance and thermal efficiency. The AVANSA 604SET SOLARU is designed for use with DN25 nominal diameter piping and is suitable for systems operating under typical solar thermal conditions. It is commonly used in conjunction with deformed stainless steel pipe ends, ensuring a secure and leak-free connection to collectors or other system components.

Brand	AVANSA

The nominal diameter (DN25) indicates the internal flow capacity of the pipe and is critical for matching the set to the correct pipe size. The 5/4 inch size refers to the external dimensions of the brass nut and must align with the pipe deformation to ensure a proper fit. These parameters are essential for correct selection and system compatibility.

Installation and connection

To install the AVANSA 604SET SOLARU, first ensure the stainless steel pipe is correctly deformed using a forming bolt. The brass nut is then placed over the deformed end, followed by the half-rings and high-temperature gasket. Tighten the nut securely to compress the gasket and form a watertight seal. It is important to verify that the pipe deformation is uniform and that the nut is fully seated against the half-rings. Common installation errors include insufficient deformation of the pipe or incorrect tightening of the nut, both of which can lead to leaks or premature failure.

Compatibility and accessories

This set is specifically designed for use with stainless steel solar piping systems. It is compatible with standard solar double pipes and is often used as a replacement part for existing installations. For new installations or additional terminations, it is recommended to order forming bolts in pairs, as one is typically retained for future use. Related products include the Deforming Bolt DN20, Solar Double Pipe, and Stainless Steel Corrugated Pipe DN16.

Technical background for designers

The AVANSA 604SET SOLARU is constructed from brass, a material known for its durability and resistance to corrosion in thermal applications. The high-temperature gasket ensures a reliable seal even under the elevated temperatures typical of solar systems. The set is designed to integrate with stainless steel corrugated piping, which allows for flexibility and ease of installation. The deformation process is critical for ensuring a secure mechanical connection, and the quality of the deformation directly affects the longevity and efficiency of the system.

Service and operation

Routine inspection of the connection is recommended to ensure the integrity of the seal and the absence of leaks. Check for signs of wear on the gasket and verify that the nut remains securely fastened. No specific service intervals are provided, but regular visual checks during system maintenance are advisable. If any damage or wear is detected, the affected components should be replaced immediately to prevent system failure.

Frequently asked questions

Can the AVANSA 604SET SOLARU be used with stainless steel corrugated pipe?
Yes, the set is specifically designed for terminating stainless steel corrugated pipe in solar thermal systems.

What is the purpose of the half-rings included in the set?
The half-rings act as support collars for the brass nut, ensuring a stable and secure connection to the deformed pipe end.

Is the high-temperature gasket reusable?
No, the gasket is a one-time-use component and should be replaced with each new installation to maintain a reliable seal.

Can this set be used for DN20 piping?
No, the set is specifically designed for DN25 nominal diameter piping and is not compatible with DN20 sizes.
