News about Gaskets, Bolt & Nuts

In the installation and maintenance of equipment and pipelines, the tightening of flange bolts and nuts may seem like a basic operation, but it is actually a key link in ensuring equipment sealing performance and avoiding leakage accidents.  Loosening too much can easily cause medium leakage, while tightening too tightly may lead to the bolt breakage and gasket loss, especially for important equipment that is prone to high temperature, high pressure, flammability, and explosion. Even a...

In mechanical assembly and daily maintenance, bolts and nuts fastening may seem simple, but there are many overlooked misconceptions that can lead to unstable equipment operation, loose connections, and even accidents. Today, we will uncover these common screw tightening misconceptions and help everyone operate correctly to ensure a secure and reliable connection. Pore mismatch The fit between bolts and nuts and holes of bolts and nuts is the foundation of fastening. If the pore is too large, the...

Did You Choose Right Flange Gaskets for The Installation of The Electromechanical System? In the flange connection of industrial pipelines and equipment, the material selection of the sealing gasket directly determines the sealing effect, equipment operation safety, and service life. The sealing gaskets made of different materials have significant differences in temperature resistance, pressure resistance, and medium corrosion resistance. Only by selecting the right material can they accurately...

Detailed Explanation of Three Types of Flange Gaskets And Their Usage Characteristics The selection of flange gaskets, as key sealing components in pipeline flange connections, is directly affected by the medium, pressure, and temperature. In the process of flange connection, gaskets play a crucial role in significantly improving the sealing performance of the connection and ensuring the stable operation of the system. Usually, there are various types of gaskets, including graphite gaskets, metal...

In the vast ocean, ships are like a moving steel castle, and every connection of this castle is crucial. The flange gasket, this seemingly inconspicuous small component, is the key to ensuring the sealing performance of ship pipeline systems. It silently withstands the tests of pressure, temperature, and corrosion, ensuring that critical components such as the ship's power system, fuel system, and cooling system do not leak. This article will take you to a deeper understanding of the relevant...

Dear everyone, today I would like to introduce to you a revolutionary material - fluororubber gaskets. It is particularly suitable for flange connection of concentrated sulfuric acid storage tanks due to its unique properties, which are the key to ensuring equipment safety and improving work efficiency. 1.​ Unparalleled acid and permeability resistance The Fluororubber gasket is a gasket...

Technical Manual for Proper Installation of Flange Gaskets: Practical Points from Selection to Leak Detection The correct installation of flange gaskets is crucial for ensuring tight sealing and reliable operation of pipeline systems. If installed improperly, it may lead to equipment failure, safety hazards, and high downtime losses. This guide provides a detailed step-by-step installation process for flange gaskets and offers recommendations for selecting gasket types based on different application...

Why Is the Gasket Quality So Important? 5 Core Reasons You Need to Know 1. Leak prevention: guarding the front line of safety The core function of gaskets is to seal the connection between pipelines and equipment. If the quality of the gasket is not qualified, it may cause medium leakage (such as gas or liquid dripping), and serious safety accidents. For example, the leakage of corrosive liquids in the chemical industry can damage equipment and pollute the environment. Failure of natural gas pipeline...

A flange is a mechanical connecting piece that plays a crucial role in the industrial field. The following are the main functions of flanges. Connection function: Flanges are usually used in pairs, with two flange discs tightly fixed together through bolts and nuts, thus achieving connections between pipelines and valves, between pipelines, and between pipelines and equipment. This connection method is not only stable and reliable but also adaptable to various complex working conditions and medium...

Technical Manual for Correct Installation of Flange Gaskets: Practical Key Points from Selection to Leak Detection The correct installation of flange gaskets is crucial for ensuring tight sealing and reliable operation of pipeline systems. Improper installation may lead to equipment failure, safety hazards, and costly downtime losses. This guide provides a detailed step-by-step installation process for flange gaskets and offers recommendations for selecting gasket types based on different application...

The selection of flange connection bolts and nuts should take into account factors such as pipeline operating pressure, operating temperature, medium type, and gasket type. For example, in the flange connection of low-pressure highly toxic medium pipelines sealed with spiral wound gaskets, although the operating pressure and temperature of the pipeline are not high, the high specific pressure required to form the initial seal of the spiral wound gasket requires the fasteners to bear a large load....

Standards, Specifications, Common Problems, Solutions, and Industry Application Characteristics of Flange Gaskets Domestic standard GB/T 9126-2020 "Non metallic Flat Gaskets for Pipe Flanges"; GB/T 13403-2013 "Gaskets for Large Diameter Carbon Steel Pipe Flanges"; HG/T 20610-2009 (Ministry of Chemical Industry Standard), SH/T 3407-2018 (Petroleum Standard).  There is a certain difference in flange gasket size between the American standard (ASME B16.20) and the national standard...
