T-piece - pipe/pipe/tube/pipe - 63x63x63; PE FIV.07704

Product detailed description

This T-piece is commonly used in heating, plumbing and irrigation systems where a branch connection is required between three 63mm PE pipes. It is suitable for installations in residential, commercial and industrial buildings, particularly in systems where flexibility and durability are essential. The design allows for a secure, leak-free connection in environments with fluctuating temperatures and pressures. Installers working with PE pipe systems will find this fitting ideal for creating T-junctions without the need for additional adapters or transition pieces.

The fitting is designed for use with polyethylene (PE) pipes of the same diameter, ensuring compatibility and ease of installation. It is commonly found in systems where the media is water or other non-aggressive fluids. The brass construction and sealing elements ensure long-term reliability and resistance to corrosion, making it suitable for both indoor and outdoor applications.

Technical parameters

Material	Body material: brass CW617N according to EN 12165
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I07704200
Brand	IVAR

The nominal pressure rating of PN 16 indicates that the fitting is suitable for systems operating at up to 16 bar. The operating temperature range from -20°C to +90°C allows for use in both cold and hot water systems. The body material, CW617N brass, is selected for its mechanical strength and resistance to corrosion, while the sealing rings ensure a tight connection under varying pressure and temperature conditions. These parameters are essential for correct sizing and selection in accordance with the system requirements.

Installation and connection

Installation of the T-piece involves connecting three PE pipes of equal diameter (63mm) to the three ports of the fitting. The connection is achieved using a compression ring and an O-ring, which are seated in the fitting and compressed against the pipe when the clamping ring is tightened. The installer must ensure that the PE pipes are cut cleanly and free from burrs before insertion. The clamping ring should be tightened evenly using a suitable wrench to avoid misalignment or damage to the sealing elements.

Common installation mistakes include over-tightening the clamping ring, which can deform the sealing rings and lead to leaks, and using the fitting with pipes of different diameters, which is not supported by the design. It is also important to verify that the PE pipes are compatible with the fitting's sealing materials and that the system pressure does not exceed the PN 16 rating. After installation, the connection should be visually inspected for alignment and tightness.

Compatibility and accessories

This T-piece is specifically designed for use with 63mm PE pipes and is not compatible with other pipe types or diameters. It is intended for use with PE pipes that have a standard outside diameter of 63mm and are suitable for the same operating conditions (temperature and pressure). No additional accessories are required for installation, as the fitting includes all necessary sealing elements. It is important to ensure that the PE pipes are of the same type and quality to maintain system integrity.

Technical background for designers

The T-piece functions by providing a branch connection between three PE pipes. The brass body (CW617N) is resistant to corrosion and maintains its mechanical properties over time, even in fluctuating temperature conditions. The sealing rings, made of NBR and CW614N brass, ensure a tight connection by compressing against the PE pipe when the clamping ring is tightened. The design allows for a secure connection without the need for welding or additional tools, making it suitable for systems where flexibility and ease of maintenance are important.

The integration of this fitting into a system depends on the overall design of the piping network. It is typically used in systems where a T-branch is required to connect a new pipe to an existing line. The operating temperature range and pressure rating are key factors in determining the suitability of the fitting for a particular application. The service life of the fitting is influenced by the quality of the PE pipes, the installation technique and the operating conditions of the system.

Service and operation

During operation, the T-piece requires minimal maintenance. However, it is important to periodically inspect the connection for signs of leakage, especially after installation or following periods of high pressure or temperature fluctuations. If a leak is detected, the system should be depressurised and the connection inspected for damage to the sealing rings or misalignment of the pipes. In such cases, the clamping ring may need to be re-tightened or the sealing elements replaced.

There are no specified service intervals for this fitting, as it is designed for long-term use under normal operating conditions. However, if the system is exposed to aggressive media or extreme temperatures beyond the specified range, the service life may be reduced. In such cases, it is recommended to consult the manufacturer's technical data sheet for guidance on maintenance and replacement.

Frequently asked questions
