Steel Flange PN16 90 mm KAN-therm 04109190 for Piping Connections

KAN-therm steel flange PN16 90 mm is a heavy-duty pipe connection component designed for use in PN16 pressure systems. Made from steel, this 90 mm flange provides a flat, standardized mating surface for bolted connections between pipes, valves and fittings. The flange is intended for installations where a PN16 rating is required and where a durable metallic connection is preferred over plastic or welded joints.

Advantages

The steel construction offers mechanical strength, good dimensional stability and resistance to deformation under tightening torque. Its PN16 rating matches common domestic and light-industrial pressure classes, enabling compatibility with a wide range of piping components. The standardized 90 mm diameter simplifies replacement and integration in existing systems and supports reliable sealing when used with appropriate gaskets and fasteners.

Suitable for (tasks / use cases)

• Bolted connections between steel pipes and pipe fittings in heating or plumbing systems
• Joining valves, pumps or other equipment to PN16-rated pipelines
• Retrofit or repair work where a flange interface is required
• Applications requiring a removable, mechanically strong joint for maintenance

Key specifications

• Material: steel
• Pressure rating: PN16 (suitable for systems designed to this class)
• Nominal diameter: 90 mm (flange face size for mating connections)
• Connection type: bolted flange interface for gasketed joints
• Application area: heating, plumbing, light industrial piping systems

How to use

Select a flange-compatible gasket and bolts rated for the system pressure and temperature. Align the flange faces with the mating component, insert the gasket between faces and fit bolts through the bolt holes. Tighten bolts progressively and in a cross pattern to achieve even compression of the gasket and the required torque specified for the fasteners. After installation, check for leaks at operating pressure and retighten bolts as recommended by the fastener manufacturer if necessary.

Usage recommendations

Before installation verify material compatibility with the conveyed medium and the operating temperature/pressure of the system. Use corrosion protection or coatings if the flange will be exposed to aggressive environments. Store flanges in a dry area to prevent surface corrosion and handle with appropriate lifting equipment to avoid damage.
