How does a continuous band sealer work?

A continuous band sealer uses heated belts to seal thermoplastic bags or pouches as they pass through the machine, providing a fast and consistent seal for packaging applications.

What factors affect the lifespan of PTFE & PEEK seals?

Discover the key factors that determine how long PTFE and PEEK seals last, including temperature extremes, pressure, chemical exposure, and material wear.

What materials are used in manufacturing spiral wound gaskets?

Spiral wound gaskets are manufactured using a combination of a metallic winding strip and a non-metallic filler material. Common metals include stainless steel, carbon steel, and various alloys, while typical fillers consist of flexible graphite, PTFE, and mica.

What are the main advantages of expanded graphite gaskets?

Expanded graphite gaskets provide outstanding thermal stability, broad chemical resistance, and superior sealability even under fluctuating temperatures and pressures, making them a reliable choice for demanding industrial sealing applications.

What is the difference between octagonal and oval ring joint gaskets?

Octagonal ring joint gaskets have an octagonal cross-section that provides multiple sealing surfaces for high-pressure applications, while oval ring joint gaskets feature a rounded profile, making them more forgiving during installation and suitable for lower pressure classes.

Are double jacket gaskets suitable for corrosive environments?

Double jacket gaskets combine a soft filler with a metallic outer shell, offering both resilience and strength. This article examines their suitability for corrosive environments, considering material compatibility, protective coatings, and potential failure modes to help you make an informed sealin......
