Solar Stainless Steel Pipe

Product detailed description

This stainless steel solar pipe is commonly used in residential and commercial solar thermal installations where reliable heat transfer and long-term durability are essential. It is typically integrated into solar collector circuits, connecting components such as collectors, heat exchangers, and storage tanks. The EPDM HT insulation ensures thermal efficiency by minimising heat loss, while the PVC protective film offers an additional layer of mechanical protection. Installers must ensure correct alignment and secure connections to maintain system integrity and prevent leaks.

The DN16 nominal bore is suitable for standard solar thermal circuits, accommodating typical flow rates and pressure levels found in such systems. The stainless steel construction resists corrosion and ensures long-term performance in outdoor and indoor environments. This product is particularly suited for systems where thermal expansion and contraction are expected, as the material properties allow for some flexibility without compromising structural integrity.

Technical parameters

Nominal bore	DN 16
Weight	0.3 kg
Code	602V16
Brand	HPW®

The nominal bore of DN16 is critical for determining the hydraulic performance of the solar circuit. It allows for sufficient flow while maintaining acceptable pressure drops. The EPDM HT insulation thickness of 13mm contributes to the overall thermal efficiency of the system, reducing heat loss during fluid transport. The PVC protective film adds durability and resistance to environmental factors such as UV exposure and mechanical abrasion.

Installation and connection

When installing this solar pipe, ensure that all connections are made using compatible fittings such as deformation nuts and pipe nuts. The DN16 thread must be aligned correctly with mating components to prevent misalignment and leakage. Check for any kinks or bends in the pipe that could restrict flow or cause stress points. A common mistake is failing to secure the protective film properly, which can lead to premature wear. Always verify that the insulation is intact and undamaged before final assembly.

Compatibility and accessories

This stainless steel solar pipe is designed to be used with standard solar thermal system components. To complete the installation, additional accessories such as deformation nuts DN16 and pipe nut sets DN16 should be ordered separately. These fittings ensure a secure and leak-free connection. The product is compatible with most solar collector circuits and can be integrated into both new and retrofit systems. Ensure that all components are from the same manufacturer or are certified for use in solar thermal applications.

Technical background for designers

This solar pipe operates as part of a closed-loop system, where the stainless steel tube carries heat transfer fluid between the collector and the storage unit. The EPDM HT insulation is designed to withstand high temperatures and maintain its structural integrity over time. The material properties of stainless steel ensure resistance to corrosion and thermal fatigue, making it suitable for long-term outdoor use. The integration of this pipe into the system depends on the overall design of the solar thermal circuit, including the number of collectors, flow rates, and system pressure. The efficiency of the system is influenced by the quality of the insulation and the accuracy of the installation.

Service and operation

Routine inspection of the pipe should include checking for signs of mechanical damage, insulation degradation, and secure connections. The protective PVC film should be inspected for cracks or abrasions that could expose the insulation to the elements. No specific service intervals are provided in the technical data, but regular visual checks are recommended to ensure continued performance. If any damage is detected, the affected section should be replaced immediately to prevent system failure.

Frequently asked questions

Can this pipe be used with glycol-based heat transfer fluids?
Yes, the stainless steel construction is compatible with glycol-based fluids commonly used in solar thermal systems.

Is the EPDM HT insulation suitable for high-temperature applications?
Yes, the insulation is designed for high-temperature environments and maintains its properties under normal operating conditions.

What is the maximum recommended length for a single run of this pipe?
The product is supplied in 60m lengths, but the actual maximum length depends on the system design and pressure requirements.

Can this pipe be bent manually during installation?
Manual bending is not recommended. Use appropriate tools to avoid damaging the insulation or the protective film.
