TEADIT NA-1122M is a high-performance, wire-reinforced non-asbestos gasket sheet material specifically designed for high-temperature and high-pressure applications, particularly saturated and superheated steam services.
Key Characteristics and Specifications
TEADIT NA-1122M is manufactured using a hot calendaring process that bonds inorganic fibers and special fillers with nitrile rubber (NBR). The addition of galvanized carbon steel wire reinforcement (the “M” designation in the product name) provides superior mechanical strength and enhanced thermal stability.
- Composition: Inorganic fibers and special fillers bonded with nitrile rubber (NBR), reinforced with galvanized carbon steel wire
- Color: Black
- Certification: Complies with ASTM F104 (F712140E33-M9)
- Anti-stick Feature: The surface is coated with a special graphite layer to prevent sticking to flanges
Service Limits and Physical Properties
According to Teadit and industry sources, NA-1122M can withstand:
- Continuous service temperature: up to 430 °C (806 °F)
- Peak temperature: up to 550 °C (1022 °F)
- Continuous service pressure: up to 102 bar (1480 psi)
- Peak pressure: up to 150 bar (2177 psi)
Applications
This material is highly effective for sealing saturated steam and superheated steam.
It has been developed to provide excellent thermal stability under extreme thermal cycling and has proven performance in sealing liquid petroleum derivatives, ethanol, chemical products, and a wide range of other industrial fluids.
TEADIT NA-1122M is suitable for use on flanges in piping systems, pumps, and equipment that require reliable sealing under high-temperature and high-pressure conditions.
