Buralloy Heat exchanger seal 2500

The Buralloy heat exchanger seal 2500 is a semi-metal gasket with a soft core and metal jacketing. The Buralloy 2500 thus combines the benefits of a compressible soft seal with the mechanical strength of a metal seal. As a result, it can be produced in many different material combinations and in different styles to suit the application.

Buralloy Ring Type Joint 2961

Buralloy ring-type joint 2961 (RTJ) gaskets are manufactured from metallic materials in compliance with American standard ASME B 16.20 and the API specification. Detailed monitoring of every manufacturing step guarantees that the sealing rings offer the necessary surface hardness. This creates a functional seal without damage to the flanges. This gasket type is used successfully in downstream refinery applications, for example. RTJ gaskets are also commonly used in high-pressure valves and the associated pipe connections and in pressure vessel joints.

Camprofile serrated gasket 9588

The serrated gasket 9588 has a concentrically-machined profile based on a 4 mm thick stainless steel base plate. This is coated on both sides with a 0.5 mm thick layer of pure graphite (purity > 98%). Thicker layers are available on request. The serrated gasket 9588 is easy to handle and is particularly suitable for applications in the chemical and petrochemical industries and in power station technology.
