ASME B16.21 Non Metal Sealing for Renewable Energy

 

 

ASME B16.21 Non Metal Sealing Gaskets can be used in renewable energy applications where a reliable and durable sealing solution is required.

The gasket is designed to provide a tight seal between two flanges in a piping system and is made from non-metallic materials such as EPDM, PTFE, or other synthetic rubber compounds. The gasket is designed to meet the ASME B16.21 standard, ensuring its compatibility with various industrial applications.

In renewable energy applications, such as solar or wind power, the ASME B16.21 non-metal sealing gasket can be used to provide a reliable seal in piping systems that transport fluids, gases, or other materials. The gasket is designed to withstand exposure to harsh environmental conditions, such as extreme temperatures, humidity, and UV radiation.

 

The non-metallic design of the gasket makes it a cost-effective and environmentally friendly alternative to traditional metallic gaskets, which can be expensive and may pose a risk to the environment. The gasket's non-metallic construction also reduces the risk of galvanic corrosion in mixed-metal systems.

Overall, the ASME B16.21 non-metal sealing gasket is a reliable and durable sealing solution for renewable energy applications, providing a tight and reliable seal while meeting the required safety and environmental standards. Its non-metallic design and materials make it a safer and more environmentally friendly alternative to traditional metallic gaskets, helping to ensure the efficiency and reliability of renewable energy systems.

Product Technical Details

As a general rule, EPDM is:

 Good for use with drinking (potable) water

 Good for use with acids

 Good ozone resistance

 Good impermeability to gases

 Good abrasion resistance

Good recovery

100% PTFE resistant to all corrosive media

Soft, twistable and bendable, used continue their service and keep its best performance.

Excellent anti-wriggle variation ability and cold current resistance. Even in case of cross change of temperature and pressure, good sealing can be assured.
