How do expanded graphite gaskets perform in oxidizing environments?

Expanded graphite gaskets generally exhibit good performance in oxidizing environments up to certain temperature limits, but their oxidation resistance depends on factors such as temperature, oxygen concentration, and the presence of impurities or protective measures.

How to calculate the torque for ring joint gasket bolting?

This article provides a step-by-step method to determine the required bolt torque for ring joint gaskets, ensuring proper sealing and joint integrity.

What is the difference between single and double jacket gaskets?

Single jacket gaskets feature a metal covering on one side only, while double jacket gaskets have metal on both sides with a soft filler in between, providing better sealability and durability for flanged connections.

Are PTFE gaskets reusable?

Discover whether PTFE gaskets can be reused, what factors affect their reusability, and when replacement is the safer choice.

When should you use a serrated metal gasket instead of a standard flat gasket?

Serrated metal gaskets are ideal for high-temperature, high-pressure applications or when dealing with uneven flange surfaces, as their serrated profile provides superior bite and sealing reliability compared to standard flat gaskets.

What is the maximum pressure rating for non-asbestos gaskets?

Non-asbestos gaskets have maximum pressure ratings that depend heavily on the material composition, temperature, and gasket design. Typical values range from 150 psi for softer types up to 1500 psi or more for reinforced materials in ideal conditions, with common flange classes such as 150 and 300. ......
