Ring Joint Gaskets

Alpi Guarnizioni ring joint gaskets are high-performance metal gaskets designed to ensure a secure seal in extreme pressure and temperature conditions.
They are used in conjunction with grooved flanges and achieve a seal through high compression load, which allows for an extremely reliable metal-to-metal coupling.

Thanks to these characteristics, Ring Joint gaskets are a proven solution for critical applications, particularly in the petrochemical, energy and process industries, where seal reliability is a fundamental requirement.

Advantages of Ring Joint seals for high-pressure systems

Alpi Guarnizioni Ring Joint seals are designed to operate in complex operating conditions where traditional sealing solutions are not sufficient.

The main advantages include:

Extremely reliable sealing at high pressures, even in the presence of fluctuating loads
Metal-to-metal coupling, ideal for high pressure class flanges
High mechanical strength, suitable for critical industrial services
Excellent performance at high temperatures
Reduced risk of extrusion, thanks to the dedicated flange seat

These characteristics make Ring Joints particularly suitable for systems where seal security and operational reliability are essential requirements.

Types of Ring Joints and profiles available

Alpi Guarnizioni Ring Joint seals are available in different types and profiles, designed to meet specific application requirements.

Choosing the correct profile is essential to ensure effective and long-lasting sealing, depending on pressure, temperature and flange type.

Available Ring Joint profiles

Oval Ring Joints
Octagonal ring joints

Types of Ring Joints

Type R: standard profile for flanges with classic seat
Type RX: designed for higher pressures, with self-energising effect
Type BX: used for extremely high pressures, typical of API applications

Industrial applications of Ring Joint gaskets

Alpi Guarnizioni Ring Joint seals are widely used in all sectors where high sealing performance and maximum operational reliability are required.

They are commonly used in:

Petrochemical industry
Refineries
Oil & gas
High-pressure process plants
