Frequently Asked Questions
Which pressure classes and sizes are available?
ASME Classes 150, 300, 600, 900, 1500 and 2500. The stated nominal size range is ½" to 60"; custom sizes are available. Confirm the size / class combination for the selected standard.
Which materials can be supplied?
Choose from the component-specific winding, filler and ring options listed above. Final material selection depends on the process media and service conditions.
Which standards are supported?
ASME B16.20 is listed as the primary gasket standard. Other dimensional or flange configurations remain subject to the project-specific requirements shown above.
Can custom sizes and configurations be supplied?
Yes. Custom dimensions and material combinations are available to project requirements. Confirm the flange geometry and service conditions with the enquiry.
How should the gasket be installed and stored?
Follow the product-specific positioning and tightening steps above. Keep unused gaskets in their original packaging in a clean, dry location away from moisture, chemicals and direct sunlight. Protect them from bending and heavy loads.
