Materials Selection of Low-Temperature Flange Gaskets

Materials Selection of Low-Temperature Flange Gaskets 1. Materials Selection of Sealing Gaskets There are various types of flange gaskets, which can be broadly categorized into three groups based on their material properties: metal gaskets, metal-nonmetal composite gaskets, and nonmetal gaskets. According to their functions, they can be classified as low-temperature-resistant gaskets, reliable sealing gaskets, and corrosion-resistant gaskets. 2. Low-Temperature Resistance Performance Commonly used...

The Application and Important Role of Flange Gaskets

The Application and Important Role of Flange Gaskets 1. Application in Pipeline Systems Flange gaskets are one of the most common sealing components in pipeline systems and are widely used in industries such as chemical, petroleum, natural gas, and power. In pipeline systems, flange gaskets are typically installed between flanges. Through compression, they seal the connections in the pipeline system, preventing medium leakage and ensuring the system's safe operation. 2. The Important Role of...

Selection of Flange Gaskets

A gasket is a mechanical seal between two objects, and if selected properly, it can usually effectively prevent material leakage between the two objects. Improper selection can result in unnecessary losses. Today, we brought you the selection methods for flange gaskets. Let's learn together. Sealing mechanism of flange gaskets The leakage occurs when the medium flows through the interface between the inner and outer spaces is the leakage of the sealing surface. The fundamental cause of...

The Sealing Mechanism of Gaskets And Main Leakage Factors

The Sealing Mechanism of Gaskets And The Main Factors Affecting Flange Gasket Leakage Sealing mechanism of gaskets Firstly, connect the two parts of the flange connection together with bolts, then pre-tighten the bolts and apply force to the gasket through the flange compression surface, causing the gasket to undergo elastic or plastic deformation and fill the flange compression surface, achieving a sealing effect. The sealing effect of flanges is closely related to the performance of gaskets and...

How to Install Gaskets? With Front Sides or Back Sides?

How to Install Gaskets? With Front Sides or Back Sides?  Is there a difference here? When installing flat washers with nuts, everyone may encounter installation problems on both sides to some extent: smooth surface and rough surface (relative). Which side should be closer to the part for better effect, and what is the big difference? First, solve one of the problems by using flat pads on both sides. We know that flat pads are mainly made by stamping iron plates, and their shape is usually a...
