Frequently Asked Questions

Can sheet gasket materials be used for sealing oil and gas pipelines?

Yes, sheet gasket materials can be used for sealing oil and gas pipelines. These materials are designed to provide a reliable and durable seal in various industrial applications, including pipeline systems. Sheet gasket materials are often made from materials such as rubber, graphite, or PTFE, which have excellent resistance to high pressure and temperature, as well as chemical compatibility with oil and gas.

What are the advantages of using non-asbestos sheet gaskets?

Non-asbestos sheet gaskets offer several advantages, including improved safety for workers, environmental friendliness, and excellent performance characteristics. They provide good resistance to heat, pressure, and chemicals, and are available in various formulations to meet specific application requirements. Additionally, they eliminate the health risks associated with asbestos exposure.

How do I choose the right gasket material for my application?

Selecting the right gasket material depends on several factors including operating temperature, pressure, media being sealed, flange type, and environmental conditions. We recommend consulting with our sales engineers who can provide technical guidance based on your specific requirements and help you select the optimal sealing solution.
