KLINGER®PSM

Characteristic & main applications

KLINGER® PSM is available in the unique AS (anti stick) or G configuration.

A tanged steel insert is included for improved blow out resistance and ease of handling.

Due to the excellent chemical and thermal capabilities of graphite it is used extensively throughout the petrochemical and chemical industries for process duties and steam applications.

Fire safe certified API 6FB.

Description

Material

Pure exfoliated graphite with a tanged stainless steel sheet reinforcement.

pT diagram

The Klinger pT diagram provides guidelines for determining the suitability of a particular gasket material for a specific application based on the operating temperature and pressure only. Always refer to the chemical resistance of the gasket to the fluid.

1. In area one, the gasket material is normally suitable subject to chemical compatibility.
2. In area two, the gasket materials may be suitable but a technical evaluation is recommended.
3. In area three, do not install the gasket without a technical evaluation.
