Theory of Marine Flange Gaskets

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...

Why Is the Gasket Quality So Important?

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...

The Selection of Flange Bolts and Nuts

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....
