Deformation screw DN16 (3/4" thread)

Product detailed description

In solar thermal installations, precise shaping of stainless steel piping is essential for secure and leak-free connections. The AVANSA deformation screw DN16 is a key tool in this process, enabling the creation of a collar on the end of the pipe. This collar is critical for ensuring that nuts and fittings can be securely fastened, maintaining the integrity of the system. Installers working with solar pipe assemblies must ensure that all deformation tools are correctly applied to avoid misalignment or leaks in the system.

Typical applications include residential and commercial solar heating systems where stainless steel piping is used for its corrosion resistance and durability. The deformation screw is particularly useful in systems where the piping must be bent or shaped to fit specific layouts. It is commonly used in conjunction with other components such as double pipes and flanged fittings to complete the installation.

The nominal diameter DN16 indicates the internal size of the pipe that the deformation screw is designed to shape. The 3/4 inch thread ensures compatibility with standard fittings and nuts used in solar piping systems. These parameters are essential for correct sizing and selection, ensuring that the deformation screw matches the pipe dimensions and thread type required for the installation.Installation and connection The deformation screw is inserted into the end of the stainless steel pipe and tightened to form a collar. This collar must be uniform and free of defects to ensure a secure connection with the nut. The 3/4 inch thread must align with the corresponding thread on the fitting. Common installation mistakes include over-tightening the deformation screw, which can damage the pipe, or under-tightening, which may result in an incomplete collar. Installers should also verify that the deformation screw is fully seated and that the collar is evenly formed around the pipe.Compatibility and accessories The AVANSA deformation screw DN16 is specifically designed for use with stainless steel solar piping. It is commonly used with the following accessories: Nut for solar pipe - set DN16, Solar double pipe, corrugated pipe DN16, and 2x16 meters. When ordering, it is recommended to purchase two deformation screws at a time, as one is typically retained for future use and the other is often misplaced during installation.Technical background for designers The deformation screw operates by applying pressure to the end of the pipe, forming a collar that provides a secure surface for the nut to grip. The stainless steel material used in solar piping is chosen for its resistance to corrosion and high-temperature performance. The deformation process must be carefully controlled to avoid work hardening or cracking of the material. The DN16 size ensures compatibility with standard solar pipe dimensions, and the 3/4 inch thread allows for integration with commonly used fittings. The success of the deformation process depends on the correct application of force and alignment of the tool with the pipe axis.Service and operation Once installed, the deformation screw does not require regular maintenance. However, during inspections, installers should check that the collar remains intact and that there are no signs of wear or deformation that could compromise the connection. If the collar becomes damaged or misaligned, the affected section of the pipe should be replaced to maintain system integrity.Frequently asked questions

Can the deformation screw be used with other types of pipe?
No, the deformation screw is specifically designed for stainless steel solar piping and is not suitable for other materials or diameters.

How many deformation screws should be ordered for a typical installation?
It is recommended to order two deformation screws at a time, as one is typically retained for future use and the other is often misplaced during installation.

Is the deformation screw reusable?
No, once the deformation screw has been used to form a collar, it cannot be reused and must be discarded.

Can the deformation screw be used with non-standard fittings?
Only if the fittings have a 3/4 inch thread and are compatible with the DN16 pipe size.
