Graphite gasket
product description

又称柔性石墨金属增强复合垫片或高强石墨垫片,它是由冲齿的金属齿板或冲孔的金属芯板与柔性石墨粒子复合压成的一种密封垫片,它通常由柔性石墨复合增强板裁制而成, 主要应用于各种 管道 阀门 压力容器 热交换器 冷凝器 发电机 空气压缩机 排气管 制冷机 等法兰连接处的密封部位可替代石棉橡胶垫片、铁包垫片。 Graphite composite gasket is also called flexible graphite metal reinforced composite gasket or high-strength graphite gasket. It is a kind of sealing gasket which is formed by punching a metal tooth plate or a punched metal core plate with flexible graphite particles. It is usually made of flexible graphite composite reinforcement plate, and is mainly used for flange connection of various pipes , valves , pumps , pressure vessels , heat exchangers , condensers , generators , air compressors , exhaust pipes , refrigerators, etc. The sealing part can replace asbestos rubber gasket and iron-clad gasket.

Performance characteristics: Good corrosion resistance, high / low temperature resistance, radiation resistance, good compression resilience and high strength. The required pretension force is smaller than that of metal gaskets and metal wound gaskets. The requirements are not high, and it is a relatively economical and practical gasket. If hemming is adopted, the excellent performance of the original graphite composite gasket can be maintained, and it is easy to install and disassemble, and is not easy to damage. At the same time, it can prevent the erosion of the gasket by the medium and oxygen in the outside air, which improves the temperature and pressure performance.

Structural form: The structure types of graphite composite gaskets are divided into RF type, MFM type and TG type, which are respectively suitable for protruding surface, concave and convex surface and tongue and groove surface flange. According to requirements, RF type gaskets can be equipped with stainless steel or carbon steel inner edging, that is, RF-E type.

✱ Non-standard price and special-shaped parts can be processed according to customer requirements.
