Frequently Asked Questions (FAQs)

Frequently Asked Questions About Static Sealing in China

What are static seals and where are they typically used?

Static seals are used in applications where there is no relative movement between the sealing element and the sealing surface. You’ll commonly find them in stationary components such as pipelines, containers, housings, and sealing plates to prevent fluid or substance leakage.

What materials are commonly used for static seals in China?

Static seals in China are often made from premium polymers like polytetrafluoroethylene (PTFE), polyethylene (PE), and polyetheretherketone (PEEK). These materials are chosen for their excellent wear resistance, low friction, and good chemical compatibility, making them suitable for a wide range of applications.

How do I select the right static seal for my application?

When selecting a static seal, you need to consider several factors, including the surface condition of the sealing face, the contact width of the sealing surface, and the properties of the fluid being sealed. A smooth surface enhances sealing efficiency, and the viscosity of the fluid affects how easily it can be sealed. Higher-viscosity fluids are easier to seal than lower-viscosity ones.

What are the key considerations for installing static seals?

Installing static seals requires attention to the cleanliness of the contact surfaces and the proper selection and application of sealants. Ensure the surfaces are free from dirt, oil, or other contaminants, and choose a sealant that is compatible with the materials and conditions of your application.

Can static seals be used in extreme conditions such as high temperatures or cryogenic applications?

Yes, static seals can be designed for extreme conditions. For example, some seals are engineered for cryogenic applications and can operate effectively at very low temperatures. Others are made to withstand high temperatures and pressures, making them ideal for use in high-temperature furnace pipelines or steam turbine installations.
