The Fixed Torque Tightening Technology of Flange Bolts and Nuts

Complete Analysis of Fixed Torque Tightening Technology of Flange Bolts and Nuts The flange connection is a common and critical structure in pipelines and equipment. It is used to connect components such as pipe sections, valves, pumps, etc. The sealing performance of flange connections is directly related to the safe and stable operation of the entire system. In flange connections, bolts and nuts play a crucial role in maintaining the integrity of the pipeline system. They must be tightened...

Introduction to Flange Bolts and Nuts

Introduction to Flange Bolts and Nuts

Introduction to Flange Bolts and Nuts What are flange bolts and nuts?  The flange bolts and nuts are the type of fastener mainly composed of a hexagonal head, a flange plate (the gasket below the hexagon is fixed together with the hexagon), and a screw (a cylindrical body with external threads). It needs to be matched with a nut and used to tighten and connect two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, it can separate...

The Sealing Principle and Leakage Form of Gaskets

The Sealing Principle and Leakage Form of Gaskets

Sealing Principle and Leakage Form of Gaskets  Basic Concepts of Gasket Sealing Gasketed sealing is the main sealing structure for detachable connections in industrial devices such as pressure vessels, process equipment, power machines, and connecting pipelines. It is usually composed of flanges, gaskets, connecting bolts, and nuts, which is collectively known as flange sealing joints.  Sealing Mechanism of Gaskets Leakage is a phenomenon that people do not want the medium to flow from...

How to Select Gaskets?

How to Select Gaskets?

How to Select Gaskets? Here are five elements of the gasket selection. If you understand them, the gasket selection is not difficult for you. Gaskets and gasket seals A gasket is a material or combination of materials clamped between two independent connectors (mainly referring to flanges), whose function is to maintain the seal between the two connectors within the predetermined service life. The gasket must be able to seal the joint surface and ensure that the sealing medium is not permeable or...

The Sealing Principle and Factors of Flange Gaskets

The Sealing Principle and Factors of Flange Gaskets

Factors Affecting Sealing of Flange Gaskets Through the pre-tightening force of the bolt, the sufficient pressure is generated between the gasket and the flange sealing surface. The deformation of the gasket surface is sufficient to fill the micro-unevenness of the flange sealing surface, thereby achieving the purpose of sealing. Today, we will explain the sealing principle of flanges and the factors that affect sealing. The minimum unit pressure that acts on the fange gaskets to achieve the above...

What Material Is the Flange Gasket Made of and How to Select It?

What Material Is the Flange Gasket Made of and How to Select It?

What Material Is the Flange Gasket Made of and How to Select It? What material is the flange gasket made of and how to select it? We all know that the flange gasket is an important tool for sealing between flanges. If the flange is not sealed properly during installation, it will inevitably affect the use of pipe fittings or equipment. The flange gasket is usually a circular ring shape, and the material used to make that the gasket has great strength and can produce plastic deformation, such as...

The Specific Performance of Flange Gaskets

The Specific Performance of Flange Gaskets

You must understand the specific performance of flange gaskets! We all know that there are small components that play a sealing role together in flange connections. They are gaskets. During normal use, flange gaskets may be affected by media, temperature, pressure, etc. However, many people are not familiar with the specific performance of different gaskets. Today, we will briefly introduce the performance of several types of flange gaskets. 1. Flange metal gaskets The flange metal gasket can be...

Affecting Factors of the Sealing Performance of Flange Gaskets

Affecting Factors of the Sealing Performance of Flange Gaskets

Affecting factors of the sealing performance of flange gaskets 1) Gasket performance Gaskets are an important component of sealing used to seal the gap between two flange sealing surfaces and prevent fluid leakage. Gaskets containing non-metallic and metallic gaskets are used to expand the distance between the gasket surface and the flange sealing surface and to achieve elasticity between the gasket surface and the flange surface. Necessary elastic deformation needs to be generated under appropriate...
