Frequently Asked Questions: Durlon® High-Temperature, High-Pressure Gaskets
What are Durlon high-temperature, high-pressure gaskets?
Durlon high-temp, high-pressure gaskets are advanced sealing solutions engineered for critical applications where conventional materials fail. Products like HT1000®, Kammprofile, and Durtec ETG withstand extreme heat, pressure, and chemical exposure, ensuring leak-free performance in demanding industrial environments.
What is Durlon® HT1000® used for?
HT1000® is a mica-based sheet gasket designed for extreme heat service up to 1,000 °C (1,832 °F). It’s commonly used in exhaust systems, incinerators, turbines, and furnaces where non-metallic gasket reliability is essential.
How does a Durlon® Kammprofile gasket work?
The Kammprofile combines a machined metal core with concentric grooves and a soft sealing layer (graphite, PTFE, or mica). This design offers high blowout resistance, excellent recovery, and reliable sealing in heat exchangers, reactors, and pressure vessels.
What makes Durlon® Durtec ETG different from other gaskets?
Durtec ETG is a semi-metallic gasket with a stainless-steel core bonded to soft sealing layers. It provides superior fire safety, chemical resistance, and blowout prevention, with service ranges from cryogenic conditions to over 1,000 °C and 6,000 psi.
Can Durlon gaskets handle steam, hydrocarbons, and aggressive chemicals?
Yes. HT1000® is excellent in superheated steam and exhaust gases; Kammprofile suits hydrocarbons, steam, and corrosives; and Durtec ETG delivers broad chemical compatibility with graphite and PTFE facings to match media requirements.
What industries rely on Durlon high-temperature gaskets?
These gaskets are trusted in oil & gas, petrochemical, refining, pulp & paper, power generation, chemical processing, and mining, where uptime, safety, and compliance with fire-safe and fugitive emissions standards are critical.
How do I choose the right Durlon gasket for my application?
Choose HT1000® when you need a non-metallic sheet for extreme temperatures, Kammprofile for high-pressure flanges with excellent recovery, and Durtec ETG when fire-safe certification and maximum blowout resistance are required.
What sizes and configurations are available?
Durlon gaskets come in standard sheet sizes, cut gaskets, and custom dimensions. Kammprofile and Durtec ETG can be manufactured to ASME, DIN, and custom flange standards, with different core materials and facing options to suit specific operating conditions.
