Pipe fixing clamp - 75mm; straight IVAR.PPA

Product detailed description

Underfloor heating systems require precise and secure pipe placement to ensure even heat distribution and long-term performance. In residential and commercial buildings, installers often use insulation boards as a base for these systems. The IVAR PPA75 fixing clamp is specifically designed for this application, providing a reliable method to anchor pipes directly to the insulation board. This ensures that the pipes remain in their intended position during and after the installation of the floor covering, preventing displacement and potential system inefficiencies.

When working with large-diameter pipes, such as 75mm, it is essential to use clamps that can accommodate the size without compromising structural integrity. The PPA75 is a straight clamp, meaning it is suitable for linear pipe runs where no bends or turns are required. It is commonly used in conjunction with other IVAR fixing solutions, such as the PPA for straight and PPB for angled pipe runs, to create a comprehensive fixing system tailored to the layout of the underfloor heating network.

Technical parameters

Material	plastic ABS
Code	PPA75
Brand	IVAR

The clamp is manufactured from ABS plastic, a material known for its durability and resistance to deformation under load. The 75mm dimension refers to the internal diameter of the clamp, ensuring compatibility with pipes of that size. These parameters are critical for correct sizing and selection, as using a clamp that does not match the pipe diameter can lead to improper fixation and potential system failure.

Installation and connection

To install the IVAR PPA75, the clamp is positioned over the pipe and secured to the insulation board using appropriate fasteners. The clamp is designed to fit snugly around the pipe, preventing lateral movement. It is important to ensure that the clamp is evenly spaced along the pipe run to maintain consistent support. Common installation mistakes include using the wrong clamp size or failing to secure the clamp firmly to the board. Always verify the pipe diameter before installation and ensure the insulation board is clean and free of debris to allow for secure fastening.

Compatibility and accessories

The IVAR PPA75 is compatible with standard underfloor heating systems that use 75mm diameter pipes. It is typically used alongside other IVAR fixing clamps, such as the PPA and PPB models, to accommodate different pipe configurations. For a complete installation, additional components such as insulation boards, fasteners, and pipe supports may be required. Installers should ensure that all components are from the same system to maintain compatibility and performance.

Technical background for designers

The PPA75 operates on a simple mechanical principle: the clamp grips the pipe and is fastened to the insulation board, preventing movement. The use of ABS plastic ensures that the clamp remains stable under varying thermal conditions. The material’s resistance to deformation is particularly important in underfloor heating systems, where temperature fluctuations can cause expansion and contraction. The clamp’s design allows for easy integration into the system layout, and its fixed size ensures that it can be used in a variety of applications without requiring adjustment.

Service and operation

Once installed, the IVAR PPA75 requires minimal maintenance. Routine checks should be performed to ensure that the clamps remain securely fastened and that the pipes are not shifting. If any movement is detected, the clamps should be resecured. As the clamp is made from durable plastic, it is not subject to corrosion or wear under normal operating conditions. No specific service intervals are required for this component.

Frequently asked questions

Can the IVAR PPA75 be used with other pipe diameters?
No, the PPA75 is specifically designed for 75mm diameter pipes. Using it with a different size may compromise the fixation and lead to system instability.

Is the clamp suitable for use in both heating and cooling systems?
Yes, the clamp is suitable for use in both heating and cooling applications, provided the system is designed for such use and the pipes are compatible.

Can the clamp be used on curved pipe sections?
No, the PPA75 is a straight clamp and is not designed for curved or bent pipe sections. For such applications, the PPB model should be used.

How many clamps should be used per pipe run?
The number of clamps required depends on the length of the pipe run and the system design. A general guideline is to space clamps evenly to ensure stable support, but specific recommendations should be followed according to the manufacturer’s technical data sheet.
